The following problems may occur when wearing contact lenses:
- Your eye may burn, sting and/or itch.
- There may be less comfort than when the lens was first placed on your eye.
- There may be a feeling of something in your eye (foreign body, scratched area).
- There may be the potential for some temporary impairment due to peripheral infiltrates, peripheral corneal ulcers and corneal erosion. There may be the potential for other physiological changes, such as local or generalized oedema, corneal neovascularisation, corneal staining, injection, tarsal abnormalities, iritis and conjunctivitis, some of which are clinically acceptable in low amounts.
- There may be excessive watering, unusual eye secretions, or redness of your eye.
- Poor visual acuity, blurred vision, rainbows or halos around objects, photophobia or dry eyes may also occur if your lenses are worn continuously or for too long a time.
