Question: I’ve heard about multifocal lenses before, but what exactly are they and how are they designed to help vision at different distances?
Progressive (Multifocal) Glasses
Answer: Multifocal lenses are specially designed lenses that combine multiple prescriptions into one lens. The top area is for distance vision, the middle area is for intermediate tasks like computer use, and the lower area is for near tasks such as reading. This allows clear vision at multiple distances without changing glasses.
