Low Vision

Low vision is the term used to describe significant visual impairment that can’t be corrected fully with glasses, contact lenses, medication or eye surgery.  Low vision causes a person to be unable to accomplish some daily tasks due to sight impairments. Low vision occurs when an individual struggles with any of the following common activities:

  • Reading
  • Everyday tasks like personal grooming
  • Viewing photos
  • Recognizing faces

Millions of Americans experience a normal loss of vision as they get older and the number of individuals who develop vision problems due to health conditions is projected to continue to rise.

There are many things that can cause low vision, including:

A few simple approaches can be:

  • Getting an eye exam
  • Update your reading glasses
  • Use bright light for reading

If these do not work for you, ask your eye care professional for help or ask for a referral to a low vision specialist.


Low Vision Technology 

Individuals with eye disease related to age, or vision compromised due to injury, may benefit from the usage of low vision devices.

There are two primary categories for low vision devices: Magnifiers for viewing things and objects that are close to you (magnifying lenses or machines), and magnifiers used for viewing objects and images at a distance (telescopic lenses). Many lighted magnifiers for close objects improve readability by increasing illumination.  With the advances in technology, many low vision devices are available to provide multiple function (near and distance) magnification and visual aid.

Technology is advancing to meet the growing needs of people with low vision impairment. There are a number of products that can help individuals with low vision. While considering the correct vision enhancer, keep in mind a few objectives:

  • What is the visual ability of the individual? Low vision aids are created with different options for specific low vision needs.
  • What tasks will the visual enhancer be used for? Find out what each product is best used for to decide if it will meet the needs of the individual.
  • Is the device easy to use? The right device should be easy for you to use.
  • How much does it cost? The cost of low vision aids can vary depending on a number of factors.

Popular products include:

Portable magnifiers and lighted magnifiers- offer magnified reading on the go. Perfect for menus, shopping lists, label reading, and more, portable magnifiers can fit in your pocket, purse, or be worn on the belt for quick, easy use.

 

Wearable magnifiers – wearable technology is the future for those with low vision who live an active lifestyle.  Wearable options make it possible to see and take part in everyday tasks, such as reading and recognizing faces.

 

Transportable magnification screens are perfect for close up viewing as well as distance viewing. These great viewers offer great flexibility, from watching TV to using the mirror image feature for self-viewing. There are APPS for smart phones that can be used to magnify reading material.

  

Desktop devices for reading books, bills or letters – these have large, bright screens. A reading table offers visual aid for reading books, optional computer connectivity and more. This family of portable magnification units offers up to 75x magnification.

 

 

Consult a Low Vision Specialist–Consider making an appointment with a trained low vision specialist if you have specialized needs. They are available in larger cities or can be found by contacting The Braille Institute or by an internet search. Talk with your low vision specialist to find out which is right for you and where you can find them.

In addition to low vision devices and good lighting, inexpensive non-optical adaptive aids can assist with routine daily activities. These devices include:

  • Large-print cookbooks
  • Large-numbered playing cards, clocks, telephones and watches
  • Electronic “talking” clocks, kitchen timers, thermometers, blood pressure meters and even pill bottles
  • Large felt-tip pens and wide-lined paper for writing notes
  • Color-coded pill boxes
  • Signature guides help in writing your signature in the correct place

Many of these items can be found at your local drugstore, discount store or bookstore. Your low vision specialist can recommend retail sources for non-optical adaptive aids.

Vision loss can definitely be alarming but learning how to adapt, with the aid of low-vision specialists, can result in continued independence.  As low vision aids are tools focused on helping with the physical aspect, it is also important to seek the help of a counselor for psychological counseling if needed or join a support group, that may provide the help you need. Finally, maintaining a social network and asking for help will enrich your life, and help maintain your independence and quality of life.

IN MY MOTHER’S EYE

There is an old Irish ditty I often heard as a little boy.  It goes something like this:

“One bright and guiding light that taught me wrong from right I found in my mother’s eyes. Those baby tales she told of roads all paved with gold I found in my mother’s eyes”.

As a blind child there was so much I found in my mother’s eyes.  From as early as I can remember, she read me stories that spanned from Robert Lewis Stephenson’s adventures like “Treasure Island” to the book that always made both of us cry – “Black Beauty.”

As a teenager and young adult, her eyes made it possible for me to venture into the world knowing as she liked to say…”dressed to the nines.” And then, when I married my wife, Patty, my mother had strong opinions about the choice of tuxedo I should wear on our wedding day.  I can still remember hearing her talk about how much she loved to see the first smiles on the faces of our children, Blythe & Tom. 

As she grew older, it was her eyes that kept her connected to the world.  Every morning, she read her Boston Globe from cover to cover, and on afternoon television she never missed her Soap Operas – “The Guiding Light,” and “Search for Tomorrow.” And then, there was the NBC Nightly News with her on-going crush on Tom Brokaw.

April is Women’s Eye Health Month along with celebrating the need for Sports Eye Safety.  I can still remember my mother crying when she watched Cleveland Indian’s left-handed pitcher Herb Score hit with a line-drive costing him his sight.  Research goes hand in hand with eye-safety to preserve vision.  The Discovery Eye Foundation is committed to finding the answers that will preserve vision and allow women and mothers the blessing of seeing the smiles on the faces of the children they love.

Too Much Screen Time:  Is it bad for kids?

Children and their phones, iPads and gaming devices are inseparable today. Most are growing up with a wide selection of electronic devices at their fingertips. They can’t imagine a world without the internet, smartphones and tablets.  Although, all that reading and playing games on their handheld devices may be harmful.  But it’s not just kids who are getting too much screen time. Many parents struggle with over use of screen time themselves.  So it’s important to understand how too much screen time could be harming everyone in the family.

Children can experience at least one of the following symptoms after being exposed to more than two hours of screen time per day:

  • Headaches
  • Neck/shoulder pain
  • Eye strain, dry or irritated eyes
  • Reduced attention span
  • Poor behavior
  • Irritability

Any of these symptoms could potentially affect academic performance and social interactions.

The worldwide rapid rise of nearsightedness has been linked to increased use of and exposure to electronic devices. However, spending more time outdoors, especially in early childhood, can decrease the progression of nearsightedness.

Blue Light can be harmful

The LED screens of computers and portable digital devices emit a broad spectrum of visible light. Most of these light rays are harmless, but a portion of the light emitted by these screens is relatively high-energy visible light called “blue light.”

Blue light has shorter wavelengths and higher energy than other visible light rays. Some laboratory research suggests certain bands of blue light may be harmful to the light-sensitive retina of the eye over time.

Blue light also plays an important role in regulating our body’s circadian rhythm. This basically is an internal clock that’s running in our brain and cycles between alertness and sleepiness at regular intervals over a 24-hour period.

Too much exposure to blue light at the wrong time of day can disrupt a person’s normal sleep/wake cycle, which can have serious health consequences.  Sleep disruption can be especially problematic for children, leading to daytime drowsiness and poor performance in school. Some authorities feel that disruption of the sleep/wake cycle also can eventually lead to weight gain and obesity-related health problems.

Research has shown that people who experience disrupted 24-hour cycles of sleep and activity also are more likely to have mood disorders, lower levels of happiness and greater feelings of loneliness.

How to cut back on screen time

  • Set a limit on daily screen time. Make it clear to your kids and stick to it.
  • Encourage your child to spend some of that screen-free time outdoors while it is still light.
  • Establish screen-free zones: For example, no smartphone use for anyone in the family in the car,  at restaurants, or at the dinner table.
  • No screens in the bedroom when it is time for bed. No exceptions.
  • As parents you can be a model for moderate screen use. Show your children, with your own behavior, how to live a rich, varied and healthy life where all habits are practiced in moderation.

It is also very important to teach your child good eye habits, below are few tips from experts:

  • You can set a kitchen timer or a smart device timer to remind them.
  • Alternate reading an e-book with a real book and encourage kids to look up and out the window every two chapters.
  • After completing a level in a video game, look out the window for 20 seconds.
  • Pre-mark books with a paperclip every few chapters to remind your child to look up. On an e-book, use the “bookmark” function for the same effect.
  • Avoid using a computer outside or in brightly lit areas, as the glare on the screen can create eye strain.
  • Adjust the brightness and contrast of your computer screen so that it feels comfortable to you.
  • Use good posture when using a computer and when reading.
  • Encourage your child to hold digital media farther away, 18 to 24 inches is ideal.
  • Create a distraction that causes your child to look up every now and then.
  • Remind them to blink when watching a screen.

Finally, it is very important to make sure your child gets a regular eye exam by a pediatric ophthalmologist or optometrist.  This will help monitor your child’s vision and eye health.

My Best Gift!

The other day my daughter Blythe asked me which Christmas I consider to be my favorite.  I had to think a minute, because as a family, the Sullivan’s have had some great ones.  I was about to say the first time you and your brother Tom were old enough to really get into Santa, being absolutely sure that the fat man brought your presents right down the chimney.  I was about to say that, and then I remembered. 

The greatest Christmas I ever enjoyed was a ski trip in Winter Park, Colorado, when our children were teenagers and our friend, the marvelous Betty White, joined us for a Christmas Eve sleigh ride none of us will ever forget.  The night was perfect.  It had snowed earlier that day, and the air had a feeling of Christmas that you could almost taste.  Oh, sure, it was cold, but we were bundled up under tons of blankets as two beautiful Clydesdale horses with bells jingling took us through the woods to a magical barn where dinner would be served and carols sung. 

It was on the way home that my Christmas was made complete.  We had stopped to let the horses breathe, and everyone was quiet, just allowing the feeling of togetherness envelope us in that special night.  It was Betty who broke the silence. 

“Tom,” she said almost to herself, “I wish I may, I wish I might, let you see the stars tonight.  I feel like we could almost reach up and touch them.  That’s how bright and close they are.  I guess when you’re this high in the Rocky Mountains, it just feels like they’re right here.”

I could hear how much my friend wanted me to see such a heavenly display, but we both knew that could never happen.  I have no complaint about being blind, no one could have a better life, but I would be lying if I didn’t admit at this holiday season that I’d love to be able to take it all in, all the special sights of Christmas. 

Every day in laboratories around this country, researchers are working to solve the multiple eye diseases that make it impossible for millions of people to see the joys of Christmas.  At this holiday season, my best gift would be that all of us donate to the Discovery Eye Foundation with its goal to preserve vision and eradicate blindness around the world.  During this season of giving, may your hearts be light and your sight be bright. 

Merry Christmas!

Keep Your Eyes Comfortable During the Cold Winter Months

Harsh weather conditions can reduce the natural moisture in your eyes and the irritation usually results in a burning or itching sensation that often leads to rubbing or scratching your eyes which can worsen the symptoms. Sometimes it feels like there is a foreign object in your eye and for some, dry eyes can even cause excessive tearing, as your eyes try to overcompensate for their lack of protective tears. Prolonged, untreated dry eyes can lead to blurred vision as well. Between the harsh winter winds outside and the dry heat radiating inside, our eyes are very quickly irritated and dried in the winter months.  The result is itchy, dry eyes that may cause pain, blurred vision, a burning sensation, or even watery vision as our eyes try to compensate for the dryness.

What Are The Symptoms?

  • Uncomfortable, stingy, burning or scratchy feeling.
  • Stringy mucus in or around your eyes
  • Increased eye irritation from smoke or wind
  • Eye fatigue
  • Sensitivity to light
  • Eye redness
  • A sensation of having something in your eyes
  • Difficulty wearing contact lenses
  • Periods of excessive tearing
  • Blurred vision, often worsening at the end of the day or after focusing for a prolonged period

10 TIPS TO KEEP YOUR EYES COMFORTABLE DURING THE WINTER MONTHS

Whatever the symptoms, dry eyes can cause significant discomfort during the long winters and relief can seriously improve your quality of life.

  1. To keep eyes moist, apply artificial tears/eye drops a few times a day. If you have chronic dry eyes, speak to your eye doctor about the best product for your condition.
  2. Drink a lot of fluids – keeping your body hydrated will also help maintain the moisture in your eyes.
  3. If you spend a lot of time indoors in heated environments, use a humidifier to add some moisture back into the air.
  4. Try to situate yourself away from sources of heat, especially if they are blowing. While a nice cozy fire can add to the perfect winter evening, make sure to keep your distance so dry eyes don’t ruin it. 
  5. Staring at a computer or digital device for extended amounts of time can further dry out your eyes. If you spend a lot of time staring at the screen, make sure you blink often and practice the 20/20/20 rule – every 20 minutes, look 20 feet away for 20 seconds. Use artificial tears often to lubricate eyes during long periods of using your eyes.
  6. Avoid air blowing in your eyes. Don’t direct hair dryers, car heaters, air conditioners or fans toward your eyes. In your car, direct heat to floor vents and away from your eyes once your windshield is defrosted.
  7. Stop smoking and avoid smoky environments.
  8. Don’t rub your eyes! This will only increase irritation and can also lead to infections if your hands are not clean.
  9. Give your eyes a break and break out your glasses. If your contact lenses are causing further irritation, take a break and wear your glasses for a few hours or days. Also talk to your optometrist about switching to contacts that are better for dry eyes.
  10. Protect your eyes. If you know you are going to be venturing into harsh weather conditions, such as extreme cold or wind, make sure you wear protection. Try large, 100% UV protective eyeglasses and a hat with a visor to keep the wind and particles from getting near your eyes. If you are a winter sports enthusiast, make sure you wear well-fitted ski goggles.

If you find that after following these tips you continue to suffer, contact your eye doctor.

I Can Only Imagine

I can only imagine my wife’s beautiful face.  Oh sure, I’ve touched it and kissed it many times.  I’ve felt the lines with the tips of my fingers, tracing our lives together, and I’ve heard her smile.  I understand that’s not really seeing it.  It’s not seeing her eyes as they sparkle with something funny I said; or, when she looks at me with love reserved only for those who are truly in love.

She’s often tried to explain the flash and colors of a sunset and the cotton softness of clouds as they drift across the sky.  And, what about a rainbow made up of all the colors that somehow promise all of us that things in the world will get better. 

How amazing it would be to see my daughter Blythe skiing her favorite Colorado Mountain trail or my son Tom riding a California wave, both so secure and happy enjoying the sports they love. 

There is so much more I wish I could see, but it’s not going to happen because I am blind.  I am left with only imagining what it’s like to have the gift of sight.

I can only empathize with how a person feels when their vision is threatened by glaucoma or diabetic retinopathy, retinitis pigmentosa, and the most devastating of all, macular degeneration.

At the Discovery Eye Foundation (DEF) our researchers are working every day to overcome the loss of vision and preserve your ability to treasure all the beauty that surrounds you.  I’ve heard it said that the eyes are the windows to the soul.  I don’t know if that’s true, but I am sure that they are the single most important sense in the group of five, and that saving vision is a cause that must be supported.

DEF is committed to that mission, and with your help, answers to all forms of eye disease will be discovered.  It’s up to all of us to support the research that’s bringing us ever closer to those solutions.

Beware of Costume Contacts

Costume Contact Lenses such as cat eyes or zombie may make your Halloween costume a bit more frightful although wearing those lenses without a prescription can be more terrifying, as it could result in vision loss or even blindness.

You can buy contact lenses, including decorative contact lenses, from your eye doctor or on the Internet.  It’s very important that you only buy contact lenses from a company that sells FDA-cleared or approved contact lenses and requires you to provide a prescription.  Even if you don’t wear corrective lenses you still need to get fitted properly.

Remember — Buying contact lenses without a prescription is dangerous!

Right now there are a lot of products that you can buy without a prescription but they may not be safe or legal.

You should NEVER buy lenses from:

  • street vendors
  • salons or beauty supply stores
  • boutiques
  • flea markets
  • novelty stores
  • Halloween stores
  • convenience stores
  • beach shops
  • internet sites that do not require a prescription

Know the Risks –

Wearing costume contact lenses can be risky, just like the contact lenses that correct your vision. Wearing any kind of contact lenses, including costume lenses, can cause serious damage to your eyes if the lenses are obtained without a prescription or not used correctly.

These risks include:

  • A cut or scratch on the top layer of your eyeball (Corneal Abrasion)
  • Allergic reactions like itchy, watery red eyes
  • Decreased vision
  • Infection
  • Blindness

Signs of possible eye infection:

  • Redness
  • Pain in the eye(s) that doesn’t go away after a short period of time
  • Decreased vision

If you have any of these signs, you need to see a licensed eye doctor (optometrist or ophthalmologist) right away!  An eye infection could become serious and cause you to become blind if it is not treated.

This Halloween season DEF wants to remind you of the importance of eye safety and to make sure to take the proper steps in ensuring the proper contact lenses. 

A New Commitment to Vision

Meet Tom Sullivan – DEF’s Ambassador of Vision

Over the last 40 years, I’ve been committed to working on behalf of blind children and their families.  My involvement has spanned the entire gamut of participation – from direct involvement in the classroom and counseling parents to hosting organized 10K races and celebrity golf tournaments that carried my name.  In that time, my wife and I raised just over $8 million thanks to the generosity of so many people.  Though my commitment to this cause has not changed, I’ve chosen to take on a new challenge that has in every way re-energized my passion. 

I’ve recently become the Ambassador of Vision for the Discovery Eye Foundation (DEF), a remarkable organization that funds cutting edge research that I believe someday will eliminate many forms of blindness.  The principle reason for my enthusiastic commitment is largely due to the fact that DEF directly funds researchers and avoids institutional restrictions.

As of this blog, DEF is engaged in ongoing efforts to understand 5 main eye diseases – Retinitis Pigmentosa, Macular Degeneration, Keratoconus, Diabetic Retinopathy, and Glaucoma.  I can honestly tell you that breakthroughs are not only on the horizon, but in many cases they are imminent.  Over the weeks and months I’ll be telling you much more, specifically about our individual research projects.  

Any help you may choose to give on behalf of people struggling with vision loss will be deeply appreciated. I look forward to having many of you join my fight for sight. Your help can make a difference! Click here to donate.

Who’s On First For My Eye’s

The Difference Between an Optometrist and an Ophthalmologist

There are a number of players on your eye-health team, among them your optometrist and your ophthalmologist. It’s not always obvious, however, what position each plays and when you should call on which professional. 

 

Optometrists 

An optometrist holds a doctor of optometry (OD) degree. An optometrist generally completes a four-year college program in the sciences, plus four years of postgraduate professional training in optometry school.

Optometrists examine eyes for vision and health problems, and correct refractive errors with glasses and contact lenses. Some optometrists also provide low vision care and vision therapy. In the United States, optometrists may prescribe medications to treat certain eye problems and diseases, and their scope of care can differ by state. While not licensed to perform eye surgery, optometrists can play a role in pre- and post-operative care, if you have eye surgery performed by an ophthalmologist.

 

Ophthalmologists

An ophthalmologist is a medical doctor (MD) or a doctor of osteopathic medicine (DO), who specializes in eye and vision care. Ophthalmologists complete four years of college, four years of medical school, one year of internship and at least three years of residency in ophthalmology. Some ophthalmologists also have one or two years of additional training to become specialists in cornea, retina, glaucoma, oculoplastics, pediatrics or neuro-ophthalmology.

Ophthalmologists perform eye exams, diagnose and treat diseases, prescribe medications and perform eye surgery. They also prescribe corrective lenses.

 

Which one do I call?

Both optometrists and ophthalmologists perform routine eye exams, and are both trained to detect, diagnose and manage eye diseases. Both can prescribe corrective lenses, and both must fulfill continuing education requirements to maintain their licenses.

If your eyes are healthy, which type of professional to see is a matter of personal preference. If you already have a medical eye problem, such as diabetes, or a family history of AMD or glaucoma, you should consider seeing an ophthalmologist. While most optometrists offer medical treatment for common eye problems and chronic eye diseases, such as pink eye, dry eye or allergies, certain eye disorders require treatment by an ophthalmologist, particularly if you need surgery, laser therapy or other specialized care.

In some cases, your optometrist and ophthalmologist may work as a team. In such a setup, the optometrist is the equivalent of your primary-care doctor, who monitors your ongoing condition and care, and the ophthalmologist is your specialist, who manages your condition medically and/or performs surgery. For routine care, you may want to check with your insurance provider to see which, if either, professional they cover and for what services.

The Brain and the Eye – How They Work Together

The Brain and the Eye

The eye works like a camera. The iris and the pupil control how much light to let into the back of the eye, much like the shutter of a camera. When it is very dark, our pupils get bigger, letting in more light; when it is very bright our irises constrict, letting in very little light.

The lens of the eye, like the lens of a camera, helps us to focus. But just as a camera uses mirrors and other mechanical devices to focus, we rely on eyeglasses and contact lenses to help us to see more clearly.

The focus light rays are then directed to the back of the eye, on to the retina, which acts like the film in a camera. The cells in the retina absorb and convert the light to electrochemical impulses which are transferred along the optic nerve to the brain. The brain is instrumental in helping us see as it translates the image into something we can understand.

The Brain and the Eye

The eye may be small, but it is one of the most amazing parts of your body. To better understand it, it helps to understand the different parts and what they do.

Choroid
A layer with blood vessels that lines the back of the eye and is between the retina (the inner light-sensitive layer that acts like film) and the sclera (the outer white part of the eyeball).

Ciliary Body
The muscle structure behind the iris, which focuses the lens.

Cornea
The very front of the eye that is clear to help focus light into the eye. Corrective laser surgery reshapes the cornea, changing the focus to increase sharpness and/or clarity.

Fovea
The center of the macula which provides the sharp vision.

Iris
The colored part of the eye used to regulate the amount of light entering the eye. Lens focuses light rays onto the retina at the back of the eye. The lens is transparent, and can deteriorate as we age, resulting in the need for reading glasses. Intraocular lenses are used to replace lenses clouded by cataracts.

Macula
The area in the center of retina that contains special light-sensitive cells, allowing us to see fine details clearly in the center of our visual field. The deterioration of the macula can be common as we age, resulting in age related macular degeneration.

Optic Nerve
A bundle of more than a million nerve fibers carrying visual messages from the retina to the brain. Your brain actually controls what you see, since it combines images. Also the images focused on the retina are upside down, so the brain turns images right side up. This reversal of the images Is a lot like what a mirror does in a camera. Glaucoma can result when increase pressure in the eye restricts the flow of impulses to the brain, causing optic nerve damage and makes it difficult to see.

Pupil
The dark center opening in the middle of the iris changes size to adjust for the amount of light available to focus on the retina.

Retina
The nerve layer lining the back of the eye that senses light and creates electrical impulses that are sent through the optic nerve to the brain.

Sclera
The white outer coating of the eyeball.

Vitreous Humor
The clear, gelatinous substance filling the central cavity of the eye.
