Diagnostic lenses

A diagnostic contact lens is a lens that serves as a test sample to determine whether this type of lens fits the user for future wear. These lenses are prescribed solely by opticians to determine whether the lens fits comfortably in the eye of the client. An optometrist examines if the tear film gets under the lens, whether the lens remains stable on the eye, and if the client sees better. Diagnostic lenses are used exclusively for this purpose and can not be purchased separately.
