Common symptoms are pain and irritation on the eyes. Below are some common contact lens complications many lens wearers might not know.

The condition is caused by irritation of the tarsal conjunctiva of the upper lids. Pre-disposing factors include poor cleaning, thick or rough contact lens edge, heat sterilization and prolonged use of the contact lenses. Symptoms of giant capillary conjunctivitis may include contact lens irritation, itching, burning and mucous discharge.
2. Contact Lens Acute Red Eye (aka CLARE) is an inflammatory reaction of the cornea and conjunctiva. This condition is mainly caused by sleeping with contact lenses. The main symptom is waking with red eyes. Other symptoms are pain, poor vision and sensitivity to light. If you have CLARE, the best way to treat it is to discontinue wearing of contact lenses. Also remember to remove your lens when sleeping.
3. Keratitis is an eye infection that affects the cornea .It is caused by bacteria, fungi and other microorganisms.
