A Fresnel Press-On Lens is typically used for what purpose?

• A. To temporarily correct vision when one eye cannot wear full lenses
• B. To permanently correct vision
• C. To correct color vision
• D. To replace contact lenses

Answer: (A)

A Fresnel Press-On Lens is used to provide temporary vision correction when one eye cannot wear a full prescription. It’s a thin, flexible sheet with grooved surfaces that can be placed over an existing lens or in front of the eye to quickly add the needed refractive power. Because it’s removable and inexpensive, it’s ideal for situations like healing after injury or surgery, or when testing a new prescription without committing to new full lenses. It’s not meant for permanent correction, it doesn’t address color vision, and it doesn’t replace contact lenses.
