Kay Pictures Occluding Patches in Wallet
The occluding patches are 6.5 cm discs that cling to the spectacle lens to obscure vision of one eye when testing the other. The patches will not stick to the face or hair and are easily removed, leaving no residue. Simply peel to remove and press onto the other lens to test the other eye.
Each patch can be used repeatedly. Wipe with a damp cloth to clean and to retain its clinging properties and keep in the wallet provided between uses.
There are three fun designs: stars, pink dots, or a yellow twirl motif, plus two plain white.
