What type of lenses provide correction for multiple focal lengths such as distance and reading?

Multifocal correction lenses are specifically designed to provide vision correction at multiple focal lengths, accommodating both distance and near vision needs. These lenses incorporate different optical powers in a single lens, which allows the wearer to see clearly at various distances without needing to switch between multiple pairs of glasses.

The design of multifocal lenses typically features progressive or bifocal segments, where the top portion of the lens is tailored for distance vision, while the lower section is optimized for reading or closer tasks. This progressive transition between different focal areas means that users can seamlessly focus on objects at varying distances, making these lenses highly convenient for individuals who require correction for activities like driving, reading, or working on a computer.

Other options, such as spherical correction, toric correction, and single vision lenses, do not provide the same functionality for multiple focal lengths. Spherical and toric corrections address specific refractive errors but in a single focus format, and single vision lenses are designed to correct one type of vision (either distance or near), not both. This highlights why multifocal correction is the ideal choice for individuals with a need for multiple focal lengths.
