Single vision glasses are eyeglasses with lenses that have a single optical prescription power across the entire lens surface, designed to correct vision for only one distance-either near or far

. They are commonly prescribed for people who are nearsighted (myopic), farsighted (hyperopic), or have astigmatism, helping them see clearly at one specific range of vision

. These lenses differ from multifocal lenses, such as progressive or bifocal lenses, which have multiple prescriptions in one lens to correct vision at multiple distances (near, intermediate, and far)

. Single vision lenses provide a consistent prescription throughout and are suitable for people who only need correction for one type of vision problem, such as distance vision or reading

. Single vision glasses are often used for tasks like driving, reading, computer work, or general daily use and are usually more affordable and easier to adapt to than multifocal lenses

. They do not have visible lines like bifocals and do not change prescription power across the lens like progressives

. In summary, single vision glasses are the most common type of lenses that correct vision at one distance only, making them ideal for people with a single vision correction need
