OCUNOX® improves the tear film and protects the surface of the eye. Due to its particularly smooth texture, OCUNOX® gently moisturizes your eyes, stabilizes the tear film and prevents tears from evaporating while you sleep. OCUNOX® contains Vitamin A, a natural component of the tear film, that supports tolerance and helps ensure that the ointment mixes well with available tears to relieve the burning sensation of dry or tired eyes. OCUNOX® helps the eyelids slide easily over the surface of the cornea and conjunctiva, keeping the eyelids smooth and preventing crusting around the eye.
