What sort of eye problems can occur with contact lenses?

Occasionally you may experience mild discomfort or redness with your lenses.
If discomfort is caused by a dirty, dusty or damaged lens, or by the lens being inside out, symptoms usually improve when the lens is removed.
More serious problems – such as corneal infection, affecting the clear tissue at the front of the eye – are very unusual but can cause irritation, pain, redness, tearing or discharge. The eyes may also be sensitive to light and vision may be blurred.
In almost all cases of infection remove your contact lenses and contact your optician.
