16 CFR Part 315; Agency Information Collection Activities: Review; Comment Request; Contact Lens Rule: FTC Project No. R511995
Contact lenses are medical devices and should be treated as such. Due to the interaction of a contact lens with a patient's tear film and epithlium, along with the potential to cause inflammation or infection, contact lens wearers should have the health of their cornea evaluated annually (or more). The individual fit of a lens type, material, shape etc, affects how a contact lens will interact with each individual and therefore a contact lens prescription should only be valid for the exact brand, materisl, power and size specified.
