You may need progressive lenses if you suffer from presbyopia, a condition that makes it difficult to focus on close-up images, reports LensCrafters. However, you should talk to your doctor to know for sure.
The traditional way to treat presbyopia is to use bifocal lenses, which have two lenses separated by a line, as LensCrafters explains. This allows you to use whichever part of the lens is necessary depending on whether you look at nearby objects, such as when reading, or looking at distant objects. However, bifocals have some drawbacks, such as image jump, which refers to the jarring break between the two lenses. The line separating the lenses is also visible, which can make you look older.
Progressive lenses, which are sometimes known as no-line bifocals, have the same general effect. However, they use a blended multi-focal lens to accomplish it, as described by LensCrafters. The focal points are adjusted to most people's natural vision. This means that the top of the lens is for distant objects, the middle is for average distances and the bottom is for close-ups. There may be some limited areas of soft focus, but these get smaller as technology progresses and are not too noticeable for most people, according to AllAboutVision.com.
However, you need to have progressive lenses fitted to your eyes individually. This ensures their ideal functioning, according to LensCrafters.
