Like all other allergies, eye allergies are also caused by reaction of immune system with foreign substances. To insure the proper cleaning and care of eye, you should decrease the lens wearing time. Most of the people wear contact lenses daily in their eyes and the chances of occurring eye allergy increases. In addition, recognition of early symptoms is vital in prevention of this problem. For instance, if you feel fine when you wear lens for eight hours, but then the eyes get red and irritated. It is a sensible decision to remove the lenses then, and not to continue to wear them for few days to avoid infection or allergy.

In most of the people with allergies, activation of the immune response results in the release of inappropriate and unfortunate high quantities of chemical mediators, and amongst them, the most common is histamine. And whenever you see these mediators, it means that allergic reactions are going to start in your eyes. These mediators are responsible for the symptoms of allergic reactions in your eyes. There are different types of allergic reactions which affect your eyes. Some major types of eye allergic reactions are atopic, vernal keratoconjunctivitis, atopic keratoconjunctivitis, hayfever conjunctivitis, medication reactions, toxic papillary reactions, and much more. If contact lens is not properly used and fitted in the eyes, then it can also enhance the allergy reaction. It would be better to consult with an eye professional or doctor before using contact lenses.
