Progressive multifocal reading glasses use a no-line lens design with different viewing areas. The lower area is for close-up reading, the middle area is for intermediate distances such as computer screens, and the upper area is for room-distance viewing.
They are designed for everyday tasks such as reading books, checking your phone, working at a desk, shopping, cooking, or looking across the room. Because the lens areas change gradually, it may take a short adjustment period when you first wear them.
