Some eye problems are minor and fleeting. But some lead to a permanent
loss of vision. Common eye problems include
-
Cataracts - clouded lenses
-
Glaucoma - damage to the optic nerve from too much
pressure in the eye
-
Retinal disorders - problems with the nerve layer at
the back of the eye
-
Conjunctivitis - an infection also known as pinkeye
Your best defense is to have regular checkups, because eye diseases do not always have
symptoms. Early detection and treatment could prevent vision loss. See an eye care
professional right away if you have a sudden change in vision or everything looks dim or if
you see flashes of light. Other symptoms that need quick attention are pain, double vision,
fluid coming from the eye and inflammation.
