Chlorine & Your Eyes

Summer time is officially here and everyone enjoys a dip in a nice, cool pool during the summer months.  While swimming is a great form of exercise and a relaxing way to cool down, the water can be hard on your eyes.

What Chlorine Does to Your Eyes –

Yes chlorine can make your eyes red!  But the real dangers in pool water aren’t just a result of your eyes coming in contact with the chemical. The redness and discomfort that sometimes accompany swimming can be caused by bacteria that linger in the water. When submerged in chlorine-treated water, your eyes lose the tear film that protects against infection.  Even though the purpose of chlorine in pools is to reduce the amount of harmful bugs, some contaminants are resistant to the chlorine that is used. This means the health of your eyes can be compromised with infections caused by bugs still lingering in the water.  

This can result in these three common eye issues:

  • Pink eye or conjunctivitis – This is one of the most common eye infections swimmers can get, as it can be either viral or bacterial and spreads quickly and easily through the water.
  • Red, irritated eyes –  This is a result of your eyes becoming dehydrated due to the chlorine and the removal of your tear film. Sometimes you may also experience blurriness and distorted vision, this is usually only temporary.
  • Acanthamoebic keratitis – This is a severe eye infection that is caused by amoeba in the water becoming trapped between the cornea and the contact lens. It can begin to live there, which can result in ulcers on your cornea and permanent damage to your vision.

 

Swimming with Contact Lenses  

Wearing contact lenses in any type of water—including a pool, hot tub, ocean or lake—puts you at higher risk for a corneal infection. Bacteria and other microbes can grow on the lenses even after just one swim. Because contact lenses sit on your eyes for an extended period of time, your eyes are then continuously exposed to chemicals, bacteria, fungi or parasites after you swim. That can lead to a painful infection, corneal damage, and even loss of vision.

To avoid any kind of infection, remove contacts altogether when swimming or use swim goggles. You can get prescription swimming goggles to help keep your vision clear and eyes healthy in the pool. Talk with your eye care provider for more information about the different kinds of swim goggles available.

If you have any of these eye infection symptoms are increasing one hour or longer after swimming, see your eye doctor right away.

Being very sensitive to light

Discharge from your eye
Eye swelling
 

With all of these risks to your eyes from chlorine, swimming might seem a bit scarier than before. However, there is no need to panic!  By taking a few safety measures, you can protect your eyes and still enjoy your time in the pool.

 

  • Wear Goggles – Wear a pair of swim goggles every time you swim. Goggles keep pool chemicals out of your eyes.

 

 

 

 

  • Wash Your Eyes – Immediately after swimming, splash your closed eyes with fresh tap water.  This washes chlorine and other chemicals off your eyelids and eyelashes.

 

 

 

  • Use Eye Drops – Use over-the-counter lubricating eye drops before and after swimming to keep the tear film balanced and eyes comfortable.

 

 

  • or Use Gel Tears – If you have dry eye, thicker artificial tears called gel tears will help protect your tear film, use these drops before putting on your goggles.

 

 

  • Stay Hydrated – Don’t forget to drink plenty of water. Staying well hydrated is an important part of keeping your eyes moist and comfortable.

 


 

Don’t miss out on the fun this summer! By taking these easy steps whenever you decide to take a dive, you can have peace of mind that your eyes and your vision are protected.

 

 

April is Sports Eye Safety Month

Basketball, Baseball and Air/Paintball Guns Top the List of Leading Causes of Eye Injuries

More than 40 percent of eye injuries that occur every year are related to sports or recreational activities. A recent study found that about 30,000 people in the U.S. went to an emergency department with a sports-related eye injury, a substantially higher estimate than previously reported. Three sports accounted for almost half of all injuries: basketball, baseball and air/paintball guns. 

Basketball was the leading cause of injury in males, followed by baseball/softball, and air/paintball guns. Baseball or softball was the leading cause among females, followed by cycling and soccer.

In support of Sports Eye Safety Month in April, we are offering athletes of all ages guidance on how to protect their eyes.

Sports-related injuries can range from corneal abrasions and bruises on the lids to more serious, vision-threatening internal injuries, such as a retinal detachment and internal bleeding. About one-third of sports related eye injuries happen to kids.

The good news is that simply wearing protective eyewear can prevent about 90 percent of eye injuries. Follow these tips to save your vision:

  • Wear the right eye protection: For basketball, racquet sports, soccer and field hockey, wear protection with shatterproof polycarbonate lenses.
  • Put your helmet on: For baseball, ice hockey and lacrosse, wear a helmet with a polycarbonate face mask or wire shield.
  • Know the standards: Choose eye protection that meets American Society of Testing and Materials (ASTM) standards. See the Academy’s protective eyewear webpage for more details.
  • Throw out old gear: Eye protection should be replaced when damaged or yellowed with age. Wear and tear may cause them to become weak and lose effectiveness.
  • Glasses won’t cut it: Regular prescription glasses may shatter when hit by flying objects. If you wear glasses, try sports goggles on top to protect your eyes and your frames.

Virtually all sports eye injuries could be prevented by wearing proper eye protection. That is why athletes are encouraged to protect their eyes when participating in competitive sports.

Anyone who experiences a sports eye injury should immediately visit an ophthalmologist, a physician specializing in medical and surgical eye care.

 


Ways to Reduce the Harmful Effects of Sun Glare

During the height of summer sunshine (and heat!), it’s helpful to discuss the importance of eye protection, including ways to reduce the harmful effects of sun glare.

Fundamentally, we need light to see. Approximately 80% of all information we take in is received through the sense of sight. However, too much light – and the wrong kind of light – can create glare, which can affect our ability to take in information, analyze it, and make sense of our surroundings.

Facts about Sunlight

Every type of light has advantages and disadvantages, and sunlight is no exception:

Advantages:

• Sunlight is the best, most natural light for most daily living needs.
• Sunlight is continuous and full-spectrum: the sun’s energy at all wavelengths is equal and it contains all wavelengths of light (explained below).

Disadvantages:

• It is difficult to control the brightness and intensity of sunlight.
• Sunlight can create glare, which can be problematic for many people who have low vision.
• Sunlight is not always consistent or reliable, such as on cloudy or overcast days.

Visible Light and Light Rays

An important factor to consider is the measurement of visible light and light rays, beginning with the definition of a nanometer:

• A nanometer (nm) is the measurement of a wavelength of light.
• A wavelength is the distance between two successive wave crests or troughs:

Wavelength - glare

• A nanometer = 1/1,000,000,000 of a meter, or one-billionth of a meter. It’s very small!

The human visual system is not uniformly sensitive to all light rays. Visible light rays range from 400 nm (shorter, higher-energy wavelengths) ? 700 nm (longer, lower-energy wavelengths).
Visible Light Spectrum - glare
The visible light spectrum occupies just one portion of the electromagnetic spectrum, however:

• Below blue-violet (400 nm and below), is ultraviolet (UV) light.
• Above red (700 nm and above), is infrared (IR) light.
• Neither UV nor IR light is visible to the human eye.

Ultraviolet Light and Blue Light

Ultraviolet (UV) light has several components:

• Ultraviolet A, or UVA (320 nm to 400 nm): UVA rays age us.
• Ultraviolet B, or UVB (290 nm to 320 nm): UVB rays burn us.
• Ultraviolet C, or UVC (100 nm to 290 nm): UVC rays are filtered by the atmosphere before they reach us.

Blue light rays (400 nm to 470 nm) are adjacent to the invisible band of UV light rays:

• There is increasing evidence that blue light is harmful to the eye and can amplify damage to retinal cells.
• You can read more about the effects of blue light at Artificial Lighting and the Blue Light Hazard at Prevent Blindness.

A new study from the National Eye Institute confirms that sunlight can increase the risk of cataracts and establishes a link between ultraviolet (UV) rays and oxidative stress, the harmful chemical reactions that occur when cells consume oxygen and other fuels to produce energy.

Sunlight and Glare

Glare is light that does not help to create a clear image on the retina; instead, it has an adverse effect on visual comfort and clarity. Glare is sunlight that hinders instead of helps. There are two primary types of glare.

Disability glare

• Disability (or veiling) glare is sunlight that interferes with the clarity of a visual image and reduces contrast.
• Sources of disability glare include reflective surfaces (chrome fixtures, computer monitors, highly polished floors) and windows that are not covered with curtains or shades.

Discomfort glare

• Discomfort glare is sunlight that causes headaches and eye pain. It does not interfere with the clarity of a visual image.
• Sources of disability glare include the morning and evening positions of the sun; snow and ice; and large bodies of water, (including swimming pools).

Controlling Glare

You can protect your eyes from harmful sunlight and minimize the effects of glare by using a brimmed hat or visor in combination with absorptive lenses.

• Absorptive lenses are sunglasses that filter out ultraviolet and infrared light, reduce glare, and increase contrast. They are recommended for people who have low vision and are also helpful for people with regular vision.
• Lens colors include yellow, pink, plum, amber, green, gray, and brown. Ultra-dark lenses are not the only choice for sun protection.
• Lens tints in yellow or amber are recommended for controlling blue light.
NoIR Medical Technologies: NoIR (No Infra-Red) filters absorb UVA/UVB radiation and also offer IR light protection.
Solar Shields: Solar Shields absorb UVA/UVB radiation and are available in prescription lenses.
• You can find absorptive lenses at a specialty products store, an “aids and appliances store” at an agency for the visually impaired, or a low vision practice in your area. Before you purchase, it’s always best to try on several different tints and styles to determine what works best for you.

More Recommendations

• Always wear sunglasses outside, and make sure they conform to current UVA/UVB standards.
• Be aware that UV and blue light are still present even when it is cloudy or overcast.
• Make sure that children and older family members are always protected with UVA/UVB-blocking sunglasses and brimmed hats or visors.

Low Vision Resources

What to do when “There’s nothing more that can be done.”

“I’m sorry, but there’s nothing more that can be done. There is no cure for your eye condition.”

In your work as healthcare professionals and health educators, it’s likely you’ve encountered a significant number of adults and older adults who have been on the receiving end of this devastating news.

When an eye care provider says, “There’s nothing more that can be done,” what he or she likely means is, “There’s nothing more I can do for you surgically.” But instead of saying, “There’s nothing more that I can do,” the discouraging message delivered to the patient is, “There’s nothing more that can be done.”

Thus, in many cases, the discussion ends there. Patients will either exhaust their resources searching for an elusive cure or become resigned to a life that is restricted and defined by incurable vision loss.

When receiving a diagnosis of vision loss, many adults who have managed to overcome a host of obstacles in their lives may now believe they are facing an obstacle with no viable solution. A natural, and understandable, initial reaction is to focus instead on the devastating losses that are seen as an inevitable accompaniment to blindness and low vision such as:

  • Loss of independence: “How will I prepare meals, clean my home, or shop? Will I become a burden to my family and friends?” 
  • Loss of confidence and self-worth: “All my life I’ve been physically active and self-reliant. Has my life as an independent person come to an end?” 
  • Loss of privacy: “I won’t be able to handle my finances independently. Will I have to surrender control of my life to someone else?” 
  • Loss of employment: “I’ll have to quit my job. How will I earn a living?” 

It’s important to let your clients and patients know that there is indeed hope—and life—after vision loss. A wide range of vision rehabilitation services enable adults who are blind or have low vision to continue living independently. The term “vision rehabilitation” includes highly trained professionals and comprehensive services that can restore function after vision loss, just as physical therapy restores function after a stroke or other injury.

Vision rehabilitation professionals include:

Additional vision rehabilitation services can include:

  • Peer support and counseling: talking with peers, sharing common concerns and frustrations, and finding solutions to vision-related problems. 
  • Vocational rehabilitation: vocational evaluation and training, job training, job modification and restructuring, and job placement. 
  • Veterans’ services: vision rehabilitation and related support services for blinded veterans of all ages. 

There are many resources available to help your patients and clients locate vision rehabilitation services. For example, the VisionAware Directory of Services allows you to browse by state and type of service, including counseling resources, support groups, low vision services, independent living skills, and orientation and mobility. The VisionAware “Getting Started” Kit provides tip sheets on specialized services and products that can assist with everyday life after vision loss.

The National Eye Institute’s National Eye Health Education Program (NEHEP) also has low vision education resources. The video, Living with Low Vision: Stories of Hope and Independence, explains how, as a health professional, you can help your patients make the most of their remaining vision and improve their quality of life by referring them for vision rehabilitation services. Share it with your colleagues, too. You can find additional resources and ideas for promoting vision rehabilitation on the NEHEP Low Vision Program page.
