Abstract: A flexible transparent mask having a vision blocking portion is positioned over the infant's “good” eye to prevent amblyopia and a large plastic corrective lens is positioned over the eye under correction, and is heat laminated to the mask during manufacture. Since the entire mask is mounted upon and removed from the infant's face in a single motion, separate application and removal of a corrective lens and a conventional patch is avoided for convenience. The mask avoids the cumbersome conventional removal, sterilization and reinsertion of a contact lens to prevent infection, or alternatively, the use of external eyeglasses which the child can peek around, unlike the preferred mask held close to the infant's face. Another embodiment uses a double-sided adhesive ring for affixing the lens over the infant's eye along with a separately applied eye patch over the “good” eye.
