Effects of UV Radiation on the Eye
Solar radiation is a potential hazard in daily life, with people working outdoors and in environments with excess exposure being highly susceptible to its destructive effects. UV interacts with biological tissues through photochemical mechanisms. Three types of UV radition exist. UV-A usually penetrates through skin layers affecting connective tissue and blood vessels. In the eye, UV-A is absorbed by the crystalline lens to protect the retina. Continuous absorption of UV-A results in damage. UV-B is absorbed by the cornea, while the conjunctiva remains exposed to damage. UV-C which has the highest energy, is absorbed by the ozone layer, however, with depletion of the ozone layer, exposure to UV-C remains a threat.
