according to a friend who works in the optometry industry, she says it's allergy season so that may cause done irritation. Frequent eye drops certainly helps me.
Also, on my latest eye doctor visit, I found out that I have bumps behind my eye lid. So I got asked to use a special eye drop called Pataday and it clears up my contact lens pretty well. But supposedly the bumps caused by allergies make me itch.
Anyway, just started using it.
