LUTEIN AND ZEAXANTHIN

Why Lutein & Zeaxanthin are vital for healthy vision.

Good nutrition is important to keep your eyes healthy.  Researchers have linked two very important eye nutrients that play a key role in healthy vision.  Lutein (LOO-teen) and Zeaxanthin (zee-ah-ZAN-thin), both are potent antioxidants and are best known for protecting your eyes and may reduce your risk for macular degeneration and cataracts.

Lutein and zeaxanthin are two types of carotenoids (kuh-RAH-teh-noids), which are yellow to red pigments found widely in vegetables and other plants and lutein is a yellow pigment, in high concentrations it appears orange-red.

Both lutein and zeaxanthin can also be found in high concentrations in the macula of the human eye.  The macula is essential for vision. Lutein and zeaxanthin work as important antioxidants in this area by protecting your eyes from harmful free radicals. It’s thought that a reduction of these antioxidants over time can impair eye health.  Along with other natural antioxidants, including vitamin C, beta-carotene (vitamin A) and vitamin E, these important pigments guard the body from damaging effects of free radicals, which are reactive molecules that can destroy cells and play a role in many diseases.  It is also believed that lutein and zeaxanthin in the macula block blue light from reaching the underlying structures in the retina, thereby reducing the risk of light-induced oxidative damage that could lead to macular degeneration (AMD).

Unfortunately, the human body does not naturally make the lutein and zeaxanthin it needs. This is why getting daily amounts of lutein and zeaxanthin through your diet or nutritional supplements can help maintain good eye health.

 

Foods that Contain Lutein and Zeaxanthin

Diets rich in these two nutrients may help hold off age-related eye diseases. The best natural food sources of lutein and zeaxanthin are green leafy vegetables and other green or yellow vegetables. Among these, cooked kale and cooked spinach top the list.

Key sources of these carotenoids include kale, parsley, spinach, broccoli and peas. Orange juice, honeydew melon, kiwis, red peppers, squash and grapes are also good sources of lutein and zeaxanthin.

In addition, egg yolk may be an important source of lutein and zeaxanthin, as the high fat content of the yolk may improve the absorption of these nutrients.

Lutein and Zeaxanthin Supplements

Because of the benefits of lutein and zeaxanthin, many nutritional companies have added these carotenoids to their multiple vitamin formulas. Others have introduced special eye vitamins that are predominantly lutein and zeaxanthin supplements.

Some popular lutein and zeaxanthin supplements include:

  • MacuHealth with LMZ3 (MacuHealth LLC)
  • EyePromise Zeaxanthin (Zeavision)
  • ICaps Eye Vitamin Lutein & Zeaxanthin Formula (Alcon)
  • Macula Complete (Biosyntrx)
  • MacularProtect Complete (ScienceBased Health)
  • MaxiVision Ocular Formula (MedOp)
  • OcuGuard Plus (TwinLab)
  • Ocuvite (Bausch + Lomb

The source of lutein in many lutein supplements is marigold flowers, while for zeaxanthin it is often red peppers. If you choose a lutein and zeaxanthin supplement, make sure it’s a high quality product from a reputable dietary supplement company.

Be sure to keep in mind that individuals sometimes react differently to certain supplements, which can have unintended effects such as adverse reactions with medications. Consult with your physician or eye doctor before trying any vision supplements.

Remember that taking dietary supplements does not replace a healthy diet. Eating a well-balanced diet that includes plenty of fruits and vegetables usually is the best way to get the important eye nutrients you need.

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.

Age-Related Macular Degeneration Month

Have you ever noticed how many people, places, things, and even a rather unattractive groundhog are designated and honored with a day, a month, or a year?  Now, I am not putting down Punxsutawney Phil because I do want him to see his shadow and promise us an early spring.  In our designation of things, we also should pay homage to values and causes that are important in our history and our health.  I am glad that I am reminded every November of our Veterans on a special day or the Presidents who have served our nation.  Certainly Dr. King’s birthday and Black History Month place an appropriate focus on issues that society is still working to solve.

So, I was delighted when I heard that February is Age-Related Macular Degeneration Month.  More than any other eye disease AMD affects the largest number of people over 65 of European lineage.  In fact, as I write this piece, over 15 million Americans are struggling within its dry form, currently an incurable condition.  It’s projected that if we are not able to solve the riddle of AMD by the year 2050, the number of senior Americans with AMD will be more than 30 million.

The Discovery Eye Foundation is committed to finding the answer that will preserve the vision of millions of people.  Right now research supported by DEF at the Gavin Herbert Eye Institute, University of California Irvine, Medical School is on the cutting edge of promising breakthroughs that could make the difference in the lives of so many.  

Please join me in supporting this most worthy effort by contributing whatever you can to DEF and its important work.  Our vision may depend on your generosity.

Mitochondrial Revolution: New Hope for AMD and Aging Diseases

How many times have we heard: “This field has been thoroughly studied, and we know all there is to know; there is no reason to continue investigating, because there is nothing more to find out on the subject”? This has been the attitude of some researchers with respect to the importance of mitochondria and diseases. For more than 50 years, we have known that mitochondria, which are the “batteries” of the cell, are critical for energy production. But many believed they did not have other major roles in the health of the cell, so when it came to developing drugs against diseases, mitochondria were overlooked.

That idea has now been turned on its head.

Mitochondria

Led by Discovery Eye Foundation (DEF) Research Director Dr. Cristina Kenney, the Mitochondria Research Group believed that, to really discover something new, you have to look in novel areas. This group has done just that. Using the transmitochondrial cybrid model, which are cell lines with identical nuclei, but with each line containing mitochondria from a different person, they have shown that the mitochondria have major regulation powers over cell behavior and expression of disease-related pathways. This is significant, because the mitochondria then become a target for therapies to combat diseases.

Kenney’s group is investigating various drugs and substances that will keep the mitochondria healthy and, ultimately, improve the health of the retinal cells in age-related macular degeneration (AMD). But it does not stop there. This same approach to developing mitochondria-targeting drugs is being pursued for drugs to treat Parkinson’s disease, Alzheimer’s disease, leukemia, various cancers, heart failure, thrombosis, stroke, diabetic retinopathy, Leber hereditary optic neuropathy, and even liver toxicity from acetaminophen.

The continued support from DEF, especially in the early stages of the mitochondria research, has fostered a new area to be opened up, specifically for AMD and diabetic retinopathy. In turn, this has allowed new collaborations among Kenney and researchers from the eye field, and laboratories studying the brain and neurodegeneration, cardiology, cancer therapies and methods to reduce side effects from cancer drugs. Kenney’s discoveries using cybrids have revolutionized the field of mitochondrial research, showing that mitochondria have wide-ranging biological effects never imagined and opening up the field of mitochondrial therapy to careful investigation.

Glaucoma – Are You At Risk?

January is Glaucoma Awareness Month and the perfect time to raise awareness for this disease. Early on there are no symptoms.  In fact, half of the people with glaucoma don’t even know they have it. Learn about glaucoma and the steps you can take to reduce your risk of vision loss.

There are several types of glaucoma, although the most common type of glaucoma is Primary Open-Angle Glaucoma, it begins at the peripheral working inward to weaken the central vision, this could lead to tunnel vision. It can cause irreversible and gradual damage of the optic nerve and vision.

You can prevent glaucoma with regular eye exams (with a visual field test) by an eye care professional and also by looking out for these subtle warning signs:

  1. Eye Pain
  2. Night Halos
  3. Tunnel Vision
  4. Blurred Vision
  5. Eye Swelling and Redness
  6. Nausea
  7. Sudden Visual Disturbance
  8. Severe Headache

Are you at risk?

Anyone can get glaucoma, but certain groups are at higher risk. These groups include African Americans over the age of 40, all people over the age of 60, and since it is hereditary, people with a family history of glaucoma, and people who have diabetes.

There are many steps you can take to help protect your eyes and lower your risk of vision loss from glaucoma. 

  1. If you are in a high-risk group, get a comprehensive dilated eye exam to catch glaucoma early and start treatment. Prescription eye drops can stop glaucoma from progressing.
  2. Even if you are not in a high-risk group, getting a comprehensive dilated eye exam by the age of 40 can help catch glaucoma and other eye diseases early.
  3. Open-angle glaucoma does not have symptoms and is hereditary, so talk to your family members about their vision health to help protect your eyes and theirs.
  4. Maintaining a healthy weight, controlling your blood pressure, being physically active and avoiding smoking will help you avoid vision loss from glaucoma.

Stay aware of the risks and symptoms and remember an annual comprehensive eye exam is key for early detection of glaucoma and other eye diseases.

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.

Our Greatest Fear

The most intimate moment in the life of a parent happens as darkness overcomes the day and you tell your children a bedtime story, tuck them into bed, and kiss them goodnight.  For years, our son Tom needed a night light to eliminate his fear of the dark and allow him to sleep.

The other day I had the privilege of referring our friend Suzanne Thornton to Dr. Sameh Mosaed, a researcher and practicing physician at the Gavin Herbert Eye Institute (GHEI) with a special interest in glaucoma. Over lunch our friend Suzanne candidly talked about her overwhelming sense of fear at her loss of vision, the recent falls she had taken, and the steps up or down she couldn’t see.  Thankfully Dr. Mosaed is very confident in Suzanne’s prognosis based on the cutting edge improvement in surgical outcomes for glaucoma due to her research at GHEI.

For 8 years I served as a member of the Academy of Ophthalmology’s Foundation Board.  In that time we conducted a number of studies in all areas of vision preservation.  The one that I believe was most meaningful occurred when we asked thousands of people to express what frightened them most in life.  Frankly, I was really surprised at the results of the study.  I was sure that people would say maybe stage four cancer, or ALS, or some other terminal disease would be the thing that would frighten them the most.  I would have imagined that they might talk about the loss of a loved one or even the fear of a natural disaster.  The results of the study were very clear.  62% of all the participants said that the loss of vision was the single most frightening possibility they would ever have to face.

The Discovery Eye Foundation is committed to relieving people of their greatest fear by supporting the research that someday may eliminate most forms of blindness.  We remain grateful for all of your support as we strive to overcome people’s greatest fear, the loss of sight

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.
