Due to the depletion of the ozone layer, the amount of ultraviolet radiation we are exposed to has increased over the past decade. We all know how important it is to protect our skin from UV light, but what about our eyes?

   The three invisible ultraviolet rays that come from the Sun are UVA, UVB and UVC. The most harmful is UVC. It is not common in nature because it is absorbed by the atmosphere, but it is present in some industrial environments where electric arc welding is used. UVC exposure can cause damage such as "welder's flash" to the cornea (clear front surface of the eye) and "welder's maculopathy" to the retina (inner layer of the eye). Therefore, eye protection while welding is extremely important.

   UVA and UVB enter the earth's atmosphere and are both thought to be harmful to the eye. UVB is stronger and therefore is thought to be more damaging; it is absorbed by the cornea and lens of the eye. UVA is weaker, yet it can penetrate deeper in to the eye. it is important to wear sun protection that screen out all types of UV radiation.

   Long-term exposure to UV light can permanently damage the structures of the eyes. Staring at the sun for too long or at a solar eclipse can cause solar retinopathy, which is damage to the eyes retina. UV light has also been linked to common conditions such as cataracts (clouding of the lens of the eye), macular degeneration (loss of central vision), pteryglum (fleshy growth that invades the clear cornea), and different types of cancers including eyelid melanoma.

  Ultra radiation not only enters the eye from the sun shining down from above, but also from reflections off the ground, especially water, snow and sand. Intense exposure to bright sunlight, especially reflected light, can produce a sunburn on the surface of your eye, which is often extremely painful. This is called photokeratitis and usually results in temporary vision loss.

   Everyone is susceptible to ocular damage from UV radiation, although people who work or spend a lot of time outside are at increased risk. The risk is greatest during the midday and during the summer months. It is extremely important to protect children, because it is possible that  the cumulative effect of UV radiation could increase the risk of developing solar related eye diseases later in life. UV eye protection is also critical to those who spend time in tanning beds.

   Optimal sun protection, year round, should include a wide brimmed hat and sunglasses. When purchasing sunglasses, be sure the lenses block 100 percent of UVA, UVB and UVC. Wrap around sunglasses are best because they eliminate light from entering from the sides of the lens. Polarized lenses do not, by themselves, absorb UV rays, but help eliminate glare and are extremely benificial to boaters, fishermen and those who spend a lot of time outdoors. Prescription sunglasses, contact lenses and intraocular lens implants are also capable  of blocking UV light, although beneficial; they should not be substituted for traditional sunglasses that cover the entire eye.

   So remember, this summer when you're lathering on your sunscreen before heading out to the beach, don't forget your sunglasses!
