Contact lenses should not be worn by patients suffering from dry eye. Dry eye is caused by instability of the tear film and is usually associated with excessive evaporation of tears from the eyes or insufficient tear production. Patients may experience dry eyes, foreign body sensation, burning sensation in the eyes, photophobia and other symptoms. Contact lenses, on the other hand, require direct contact with the cornea and conjunctiva, and wearing them increases the demand for the amount of tears, which may aggravate eye discomfort. In addition, most of the corneal epithelium of patients with dry eye disease will have punctate defects or epithelial defects. After wearing contact lenses, this can exacerbate inflammation of the ocular surface, which may lead to epithelial detachment and cause eye infections. Keratitis and corneal ulcers may also occur. Therefore, contact lenses should not be worn for dry eyes. If myopia is present, frames can be worn to correct vision. Normally, you also need to pay attention to eye cleaning and hygiene, and avoid excessive eye use.
