Which lens type is designed to provide clear vision at all distances?

The lens type designed to provide clear vision at all distances is the progressive lens. Progressive lenses offer a gradual change in lens power from the top to the bottom of the lens, allowing wearers to see clearly at varying distances—far, intermediate, and near—without the visible lines found in bifocals or trifocals. This seamless transition in lens power enhances visual comfort and functionality, making progressive lenses particularly suitable for those who require multifocal correction but prefer a more aesthetically pleasing and versatile option. With these lenses, users can enjoy the convenience of a single pair of glasses for all their visual needs, accommodating activities such as reading, computer work, and distance viewing.
