I advise you not to wear contact lenses when you are diagnosed with corneal abrasion. As contact lenses have a poor breathability and they almost attach to the cornea so that the cornea could not get into contact with the air, which make eyes itchy. Worse still, soft contact lenses adsorb the protein, lipid and collagen in the tears and make them deposit in the surface of lens, breeding germs, as a consequence, cornea hydroncus, response of corneal newborn blood vessel and anaphylaxis occur, which do harm to the cornea and conjunctiva. Therefore, you had better not wear contact lenses at this moment, otherwise it will worsen your corneal abrasion.
