Although contact lenses suit most people, there are cases where the eye refuses to adjust to the alien body and might result in irritation, itchiness, or other ailments. It is advised to consult a physician before going in for a contact lens fitting. If the contact lenses do not suit the eyes they might result in complications as severe a loss of vision.
