The phrase ‘allergic reaction’ could be causing up images of hives or the sudden sensation of restricted airways, but did you recognize that an allergy can develop slowly? After all, you will gradually become allergic to belongings you use every day, like your soap, favorite beverage, or maybe your contact lenses.

If you develop an allergy with contact lenses, you’ll first notice some itching and irritation. If the condition is not taken care of promptly then feeling of heaviness within the eyelids, redness, swelling, and discharge may develop.

As your eye responds to the contact lens, inflammation causes small bumps formation under the eyelids called papillae. The bumps are visible when a doctor inverts the eyelid to have a glance. When these bumps continue to enlarge - and that they can get as big as a millimeter each called giant papillary conjunctivitis - the condition worsens and your eyes become very sensitive to bright light and contact lenses.

So don’t get frustrated - It is possible that you are allergic to your contact lens material (if hygiene and disinfection is proper) or maybe you are allergic to any ingredient of contact lens solution.
