MULTYFOCALS
Multifocal eyeglasses, also known as progressive lenses, are lenses that have multiple focal points in one lens. They are designed to correct vision at different distances, so you can see clearly at all distances without the need to switch between multiple pairs of glasses.
Unlike bifocal lenses, which have only two distinct regions for near and far vision, progressive lenses have a gradual transition between these regions, which makes them more natural to use. The upper part of the lens is used for distance vision, the middle part for intermediate vision, and the lower part for near vision.
Multifocal eyeglasses are often used to correct presbyopia, an age-related condition in which the eye loses its ability to focus on close objects. They can also be used to correct other vision problems, such as myopia, hyperopia, and astigmatism.
It’s important to note that multifocal eyeglasses may take some time to adjust to, as your eyes and brain get used to the different focal points in the lens. However, once you get used to them, they can be very convenient and provide clear vision at all distances.
