Which kind of computer glasses are the best?Įye specialists recommend that adults have their eyes examined once every one or two years. However, there may be limited areas of focus due to the line-free design. Progressive Addition Lenses (PAL) offer continuity of vision by eliminating lines between segments of different focal power. Trifocal glasses have lenses that combine a segment for far vision, another for near vision, and a third one for vision at the screen distance (a distance between the far and near segments).Īs with bifocal lenses, there may be limitation to the viewing areas. This means more up-and-down head movement may be required to view all parts of the screen. Segmented lenses like bifocals and those mentioned below have a smaller area for viewing the screen. Bifocal lenses also distort images of objects in the peripheral zone of vision. The disadvantage of this option is that objects farther away than the screen are blurry. Bifocalīifocal glasses can be prescribed so that the upper segment is set up for the screen distance and a lower segment for work that is closer than the screen (reading distance).

The disadvantage of this option is that both distant objects and reading materials that are closer than the computer screen will appear blurry. This option allows users to view the whole screen with a minimum up-and-down head movement. Monofocal or single-vision glasses designed for computer work will provide the appropriate optical correction for the working distance between the screen and the computer user's eyes. Such a forced position can cause neck and shoulder pain and it can also cause arm and low back pain.ĭepending on the individual's vision and type of work, there are several options while selecting computer-specific glasses, such as: Monofocal Many people will either lean in or lean backwards to find the right spot in their lenses where they can see best. They tend to force the wearer to tilt the head back in order to focus on the screen while looking through the lower segment of the bifocal lenses. Generally speaking, bifocals are not necessarily designed for computer work. These specialty glasses called task-specific are designed to meet the visual needs of the activity. There are other activities such as for example playing piano (piano glasses) or shooting (shooting glasses) that also require a similar custom fitting. They allow you to focus your eyes on a computer screen, which is farther away than reading material is normally held. Computer glasses are prescription glasses that are designed to wear when doing computer work.
