How Light Can Damage Eyes

All light is a form of energy. When your eyes absorb light, the process creates heat or chemical reactions in eye tissue. These reactions can cause permanent damage if the eye’s natural ability to heal itself is overwhelmed, in order to protect your eye from the light please wear fake ray ban sunglasses.

Different parts of the eye absorb different kinds of UV radiation and light. For example:

  • The surface layers of the outer part of the eyeball (the cornea and the conjunctiva) absorb UVB rays.
  • The lens absorbs mainly UVA rays.
  • The retina (the light-sensitive lining at the back of the inner eyeball) absorbs visible light.

If eyes are overexposed to ultraviolet radiation, the front portion of the eyes may be damaged. If visible light is too bright or intense, or if you stare directly at the sun,wear replica ray ban sunglasses even briefly, the retina can be damaged, causing permanent loss of vision. UV radiation, along with wind and drying of the eye, may cause snow blindness, an uncomfortable but temporary condition. There is some evidence that daily exposure to UV radiation in very bright sunlight over many years may increase the risk of developing cataracts. Catatacts cause a gradual clouding of the natural lens of the eye.
