Not many people realize that the eyes are the organs that are susceptible to corruption . Layer that coats the eye, the cornea , has a thickness of only 0.5 mm . Therefore , the eyes need to be protected , not only during a solar eclipse , but also every day .
Ultraviolet light ( UV ) apparently is one of the main causes of radiation injury to the human eye . Most of the radiation is absorbed by the cornea . Similar to skin damage caused by sunburn , damage is caused by the accumulation of radiation on the corneal epithelium .
Exposure to high intensity UV light, such as in a solar eclipse, can directly cause serious damage to the eye. Not only that, exposure to UV radiation daily which is excessive in the long term associated with the emergence of the disease in the surface of the eye, even also related to the development of cataracts and cancer.
What Happens When Eyes Staring high intensity light
UV rays, especially above 1524 m, can cause retinal damage. For example, looking at the sun directly with the naked eye, especially during a solar eclipse. Damage to the retina caused by so-called solar retinopathy.
The emergence of point blank or blurred vision in one or both eyes are symptoms that are commonly felt after exposure. Loss of vision due to UV rays is generally the case for at least a month and may not be able to return to normal.
There are also other disorders called ultraviolet keratitis, which burns on the surface of the eye (cornea). Corneal protect black sphere called the iris of the eye and act to protect structures in the eye. Damage to the cornea can be characterized by symptoms such as watery eyes, blurred vision, red eyes, and sensitivity to light. In addition to pain, damage to this area can cause interference with the vision to completely lose sight.
To avoid solar retinopathy and ultraviolet keratitis, it is advisable to see a solar eclipse through binoculars, film paper or photogravure, until the special glasses. Keep in mind that this advice is also worth doing if you are facing exposure to other high intensity light.
Besides the sun, disorders of the cornea can also be sourced from other things, as a result of exposure to light of a camera flash too often, the lights in the salon that has care skin darkening / tanning, halogen lamps, or light beam flashlight too close with eyes.

That is why people with certain professions are often exposed to the sun such as surfers, farmers, and fishermen more at risk of pterygium. Pterygium typically appears in adolescence or usian 20s. Cancer and cataract associated with exposure to UV rays usually show up after many years later.
