Prolonged contact lens wear can result in dryness of the eye. Patients with dry eyes should be cautious when using contact lenses, as the risk of complications like infection are higher.


Allergy & Giant Papillary Conjunctivitis

People who use contact lenses for several years often get an allergic reaction to the contact lens. A common form of allergy is known as giant papillary conjunctivitis (GPC). The person may experience discomfort, itching, mucous discharge or redness with wearing of the contact lens. This tends to get progressively worse with continued use.


Contact Lens Overwear Syndrome

Contact lenses reduce the oxygen supply to the cornea. People who use contact lenses for long periods or who sleep with the lenses may damage the cornea, resulting in a breakdown of the surface layer and swelling of the cornea. This results in a pain, redness, tearing and blurring of vision. In some instances, much of the surface may be left with a large epithelial defect which exposes the eye to a significant risk of potentially serious eye infection.


Contact Lens Infections

Contact lens infection can arise from inadequate lens hygiene or overuse of contact lenses. Micro-organisms from the contact lens may penetrate the corneal surface and infect the cornea tissue resulting in a corneal ulcer.

Corneal ulcers are serious conditions and are potentially blinding. The symptoms are pain, redness, tearing and blurred vision. Medical consultation should be sought immediately so that treatment can be instituted promptly to prevent worsening of the condition and loss of vision.
