Wearing contact lenses has a certain probability of damaging the cornea, but if you pay attention to the way you wear them and the hygiene of your eyes, the probability of damage is relatively low. Because contact lenses are a type of corneal contact lens, they may cause mechanical damage to the cornea, i.e. corneal epithelial abrasions, because they are worn in contact with the cornea. In addition, contact lenses may hinder the cornea’s need for oxygen and may prevent the cornea from exchanging tears with tears, which may lead to a lack of water and oxygen in the cornea. If you wear contact lenses with poor eye hygiene or incorrect wearing style, it may also lead to bacterial infection of the cornea or conjunctiva, causing bacterial conjunctivitis or keratitis, which can damage the cornea. Therefore, it is possible to damage the cornea by wearing contact lenses, but if you pay attention to your eye habits and eye hygiene, the probability is low.
