The major signs and symptoms include itching and a clear or white stringy discharge. A “cobblestone” appearance is typical. It is commonly associated with contact lens use. Foreign bodies and ocular sutures or prosthetics may be causal as well. Treatment typically involves avoidance of the inciting process or use of ocular anti-inflammatory agents such as cromolyn sodium or topical corticosteroid.
This seems to be a much bigger issue now than when I was a kid, so much environmental influence too I think.
