How they work

Special computer optics acts as a kind of filter that prevents the effects of light and radiation on the eyes. Lenses are almost never colorless.

To cut off the blue-violet color spectrum and preserve the clarity and color reproduction of images without undue stress, they are covered with a protective layer of yellow, green or purple. Additionally, cutting-edge optics are coated with an anti-reflective layer, necessary to neutralize random glare.

At the same time, there are nuances of using such a “filter”:

Since getting used to it occurs gradually, at first it is recommended to wear anti-reflective glasses (AO) no more than 3 hours a day.
You can not use AO without the need: wearing outdoors can lead to absolute isolation of the eye from the sun, and provoke the “dry eye” syndrome, i.e. inability to lacrimation and vulnerability to light.

When buying protective anti-reflective optics with diopters, you need to choose a product 2 diopters weaker.

Varieties

In optics, you can purchase the following types of anti-glare glasses for a computer:

With monofocal lenses - designed for people with normal vision. This is a standard optic that allows you to cover a wide field of view.
With bifocal lenses, i.e. with dual focus. The optical zones in them are divided in such a way that one part is adapted for image perception at a close distance, the other - for focusing on the monitor. In this case, objects in the distance will not be clear.
With progressive lenses - divided into segments that do not have a visible border. They allow you to quickly "switch" vision from objects outside the monitor to the image on the computer without discomfort. 3 segments are adapted for viewing at a great distance ( top part), to perceive the "picture" on the monitor as a whole (middle wide part) and to focus at close range (small, lower segment).

Models with progressive lenses are considered the most practical, because. allow you to equally comfortably view objects and images at any distance.
