Or, if you are very nearsighted, you may need to wear them full time. Generally, a single vision lens is prescribed to provide clear vision at all distances. These can be supplied in various thickness indexes, allowing for thinner lens options the higher the myopic prescription is.
However, patients over the age of 40, or children and adults whose myopia is due to the stress of near vision work, may need a bifocal, extended focus or progressive addition lens. These multifocal lenses provide different powers or strengths throughout the lens to allow for clear vision at distance, intermediate and near viewing.
Recent research indicates that spectacles have the ability to correct nearsighted blur, but has no effect in reducing the progressive nature of myopia. There are fortunately several spectacle lens options with variable effectivity in reducing the progressive rate of myopic decline such as:
