Most people are aware of how harmful ultraviolet (UV) radiation is to the skin. However, many may not realize that UV rays can harm the eyes and affect their vision.

Exposure to excessive amounts of UV radiation over a short period of time can cause extreme sensitivity to light and excessive tearing. It can be painful and feel like a sunburn to the eye. The longer the eyes are exposed to UV radiation, the greater the risk of developing eye disorders such as cataracts or macular degeneration. Fortunately, sun protection and preventative options are available to offer UV protection.

Types of UV Radiation

There are three types of UV radiation:

UV-C rays are the highest energy UV rays, and potentially the most harmful to eye and skin health. Fortunately, it is absorbed by the ozone layer, virtually blocking all harmful UV-C rays. If, however, the ozone layer depletes, high-energy UV-C rays could potentially reach the earth's surface and cause serious health problems.

UV-B rays emit lower energy than UV-C rays. These rays are partially absorbed by the ozone layer, but some still reaches the earth's surface. In low doses, UV-B radiation can stimulate the production of melanin, causing the skin to darken. In higher doses, however, UV-B rays can cause sunburn that increases the risk of skin cancer, premature aging of the skin, and wrinkles.

In high short-term exposure, UV-B rays can also cause photokeratitis, a painful inflammation of the cornea.

UV-A rays have lower energy than UV-C and UV-B rays, but it can pass through the cornea and reach the lens and retina of the eye. Overexposure to UVA radiation can cause the development of cataracts and the development of macular degeneration.

How Do UV Rays Affect Eye Health?

Short and long term exposure to UV radiation can harm the eyes, affect vision, and compromise overall eye health. Eye diseases and conditions caused by exposure to UV radiation include:

Macular Degeneration, also known as AMD, is caused by damage to the retina over time. It is the leading cause of age-related blindness and extended exposure to UV light may increase the risk of developing this condition.

Cataracts are a condition in which the natural lens (the part of the eye that focuses on light we see) is clouded. Exposure to UV light, especially UV-B rays, increases the risk of contracting cataracts.

Pterygium, also known as surfer's eye, is a pink, non-cancerous growth that forms on the layer of conjunctiva. Exposure to UV light increases the risk of developing these growths.

Skin cancer in and around the eyelids is also associated to extended UV exposure.

Photokeratitis, also known as corneal sunburn, is the result of high short-term exposure to UV radiation, especially UV-B rays. Long hours at the beach without proper eye protection can cause this condition, and it can be very painful. It can also cause temporary vision loss.

Prevention and Treatment

We all use sunscreen to protect our skin from harmful UV rays. Protecting our eyes is just as important. Sun damage to eyes can occur anytime during the year, and prevention is the best treatment. Be sure to wear UV-blocking sunglasses and broad-brimmed hats whenever you are outside. Never look directly at the sun, which can damage the eye's retina.

To provide adequate protection for your eyes, choose sunglasses carefully. They should:

Block out 99 to 100 percent of both UV-A and UV-B radiation;

Screen out 75 to 90 percent of visible light;

Have lenses that are perfectly matched in color and free of distortion and imperfection

Provides more coverage such as over-sized glasses

Additional precautions include:

Do not use sunlamps, tanning beds, or tanning booths

Wear UV-blocking goggles when surfing, swimming, or snowboarding

Wear a wide brimmed hat when outdoors

Avoid prolonged exposure to direct sunlight by staying in the shade, especially between 10am and 4pm

If your eyes are ever impacted by UV rays to an extent that you believe could be causing vision problems, you need to see an eye doctor immediately.

UV radiation, whether from natural sunlight or artificial UV rays, can seriously damage your eyes.

Most people probably understand the link between ultraviolet (UV) radiation and skin cancer. But many are less aware of the connection between UV radiation and eye damage.

With increased levels of UV radiation reaching the Earth's surface, it is important to take the necessary precautions to protect your eyes.

What Is UV Light?

The sun's primary danger to us comes in the form of UV light or radiation. UV radiation is a component of solar radiation. Artificial sources like welding machines, tanning beds, and lasers can also give off UV radiation.

There are three types of UV radiation. UV-C is absorbed by the ozone layer and does not present any threat. UV-A and UV-B radiation can have adverse long- and short-term effects on the eyes and vision.

How Does UV Light Affect Eyesight?

Both long- and short-term exposure to UV radiation can harm the eyes, affect vision, and compromise overall eye health. There are several eye diseases and conditions caused or aggravated by exposure to UV radiation, such as:

Macular Degeneration. Macular Degeneration (AMD) is caused by damage to the retina over time and is the leading cause of age-related blindness. Extended exposure to UV light increases your risk of developing macular degeneration.

Cataracts. A cataract is a clouding of the eye's natural lens -- the part of the eye that focuses the light we see. UV light, especially UV-B rays, increases your risk for certain types of cataracts. It is estimated that 10% of all cataract cases are directly attributable to UV exposure.

Pterygium. Often called "surfer's eye," pterygium is a pink, non-cancerous growth that forms on the layer of conjunctiva over the white of your eye. UV light from the sun is believed to be a factor in the development of these growths.

Skin Cancer. Skin cancer in and around the eyelids is also linked to prolonged UV exposure.

Photokeratitis. Also known as corneal sunburn or "snow blindness," photokeratitis is the result of high short-term exposure to UV-B rays. Long hours at the beach or skiing without proper eye protection can cause this problem. It can be very painful and may cause temporary vision loss.

Who Is at Risk?

Everyone (including children) is at risk for eye damage from UV radiation that can lead to vision loss. Any factor that increases the amount of time you spend in the sun will increase your risk. If you answer yes to more than one of these questions, you may be at higher risk of UV radiation damage to your eyes:

Do you spend long hours in the sun? (Skiing, mountain climbing, swimming, at the beach, etc.)

Do you use a sunlamp, tanning bed or booth?

Do you live in the mountains or the US Sunbelt?

Have you had cataract surgery (in one or both eyes) or do you have a retinal disorder?

Are you on certain medicines, such as tetracycline, sulfa drugs, birth control pills, diuretics and tranquilizers (that increase the eye's sensitivity to light)?

Are you a welder, medical technologist or do you work in the graphic arts or in the manufacturing of electronic circuit boards?

How Can You Protect Your Eyes from UV Light?

Know the dangers. UV rays can come from many directions. They radiate directly from the sun, but they are also reflected from the ground, from water, snow, sand and other bright surfaces.

Wear proper eye protection and hats to block the UV rays. To provide adequate protection for your eyes, sunglasses should:

Block out 99 to 100 percent of both UV-A and UV-B radiation

Screen out 75 to 90 percent of visible light

Be perfectly matched in color and free of distortion and imperfection

Have lenses that are gray for proper color recognition

If you spend a lot of time outdoors in bright sunlight, wrap around frames can provide additional protection from the harmful solar radiation. Lastly, don't forget about protection for your children and teenagers, as they typically spend more time in the sun than adults.
Be sure to see your Vision Source eye doctor at least every two years for a comprehensive eye examination. It is a good way to monitor your eye health, maintain good vision and keep track of your solar radiation protection needs as well as new advances in eye protection.

Blue light is part of the visible light spectrum. The sun emits blue light, as do artificial light sources, such as LEDs, computers and smartphones. Some types of blue light can be beneficial, helping us regulate our bodies' internal biological clocks.
However, blue-violet light can be harmful to the eyes, specifically the retina. It is a risk factor for the onset of age-related macular degeneration a deterioration of the part of the retina responsible for sharp, central vision.
A recent study found that Americans spend almost 2 ½ hours on their tablets and smartphones every day. In addition, most offices and stores use fluorescent light bulbs, and LED lights are becoming increasingly popular.
