Eye Redness
The development of eye redness with contact lens use is
always a warning sign. At the least, it may mean that the
lenses have been in too long, and should be removed. Many
conditions can cause eye redness, but contact lens use
makes certain problems more likely. Often, a red eye with
contact lens use is treated like a case of conjunctivitis
(pink eye), when actually the redness may be due to a
contact lens related allergy or infection. Some common
causes of a red eye with contact lens use include:
● Lens allergy, lens solution
allergy, or allergy to protein build-up on lenses.
● Lens overwear with corneal
edema, with corneal drying or a tight contact lens
syndrome.
● Interaction of bacterial
toxins (from the eyelids) trapped beneath the contact lens
leading to corneal irritation (phlyctenulosis).
● Corneal ulcer.
● Giant papillary
conjunctivitis.
● Poorly fitting or defective
contact lenses.
Eye redness associated with contact lens use should not be
ignored, and the eye should be examined by an
ophthalmologist to determine the cause.
