What are multifocal lenses designed for?

Multifocal lenses are specifically designed to provide clear vision at multiple distances, which is their primary function. These lenses incorporate multiple focal points, allowing the wearer to see clearly both up close and far away without needing to switch between different pairs of glasses. This versatility makes them ideal for individuals who experience presbyopia, a common age-related condition that affects the ability to focus on near objects.

The design of multifocal lenses generally includes progressive lenses, which offer a gradual transition between different lens powers, ensuring a smooth visual experience across different distances. This feature allows users to engage in various activities, including reading, computer work, and driving, without the hassle of changing glasses.

The other options do not accurately reflect the purpose of multifocal lenses, as they do not solely focus on distance vision, are not primarily intended for outdoor use, and are not limited to reading only. Multifocal lenses are meant to accommodate a range of vision needs rather than being restricted to a single distance or activity.
