ABSTRACT The corneal thickness of twenty‐two male subjects was measured before and after wearing a hard and flexible contact lens on one eye. A significant corneal thickness change was found on the eye wearing the contact lens and especially during the hard contact lens session. The contralateral eye not wearing the contact lens did show less variation during the hard contact lens session and not significant variation during the flexible session. The variations of corneal thickness could be attributed to an osmolarity effect, a decrease in glycogen content of the cornea or a significant decrease of transcorneal potential.
