This is not an infection. It is not contagious. This is an inflammatory response on the inside of the upper lids caused by continually wearing either a dirty or defective lens. It can occur with all types of lenses. It was more prevalent when soft lenses were replaced annually. Since the advent of daily disposables, it is much less common. It is treated by discontinuing lens wear for 30-60 days and with steroid eye drops.
These occur from the protein in the tears adhering to the lens. This is caused from wearing the same lens over and over. It can also occur in a simular manner with rigid gas permeable, hybrid, and scleral lenses. Because those lenses are rigid, it is easier to remove with a good cleaning. Sometimes an in office polishing can remove them. Wearing a dirty lens can cause GPC, and can make lens wear intolerable.
This can occur from wearing a lens that no longer fits correctly on the eye. The cornea can change shape due to medications, hormone changes, pregnancy and an array of eye diseases. A good fit can become too tight which can cause compromise vision.
This can be caused due to a number of reasons.
Conjuntivitis -Pink Eye Caused from:
Not washing hands prior to inserting or removal
Not changing soaking solution daily
Not keeping the storage case clean
Over wearing contacts
Poor contact lens fit
Allergy to contact lens solutions
