Between 50 and 90% of computer users are concerned about blurred vision, redness, dryness, eye fatigue, and headache. Of the variety of manifestations of computer visual syndrome, the most alarming is perhaps a decrease in vision.
At a young age, it can be associated with weakness of the ciliary muscle and manifest itself if necessary for a long time to focus your eyes on the computer screen or quickly switch attention from the keyboard to the monitor and vice versa. Upon reaching 40 years, such manifestations mean the development of presbyopia. age-related weakening of accommodation.
In an attempt to parse the image on the screen, we lean forward or throw our head back, trying to look through the bottom of the spectacle glasses. An uncomfortable pose leads to excruciating pain in the neck and back.
Special glasses for the computer will help reduce eyestrain and ensure comfortable work with the computer.
You hardly thought that your reading glasses or constant wearing glasses may not be suitable for working with a computer.
The fact is that the screen is located at a distance of 60-70 cm from your eyes, in the so-called intermediate zone of vision. Reading glasses are designed to work at close range (30-35 cm). Glasses for continuous wear correct vision in the distance, in bifocal, in addition, there is a segment for reading.
Multifocal and progressive spectacle glasses contain a small section of the intermediate zone, which does not provide sufficient convenience, unlike glasses for a computer.
To work at the computer a wide variety of spectacle glasses is presented:
- Simple (monofocal) lenses provide clear vision at a distance of the screen, relax the ciliary muscle and provide the widest view. This reduces eyestrain, the risk of blurring vision and eliminates the need for an uncomfortable posture, which leads to pain in the neck and back.
Such glasses are suitable for users of any age.
- Professional progressive lenses consist of three segments seamlessly transitioning into each other, which provide clear vision near, in the intermediate zone and partially into the distance. The intermediate segment, wider than conventional progressive glasses, is designed to work with a computer.
Please note that the remaining small segment for the distance is not suitable for driving a car!
- Professional multifocal lenses consist of three separate segments: for near, far and wide intermediate. The upper part of professional bifocal lenses is designed to work with a computer, and the lower one is for reading.
Glasses with professional bifocal, multifocal and especially progressive glasses are convenient for users with presbyopia.
- Clip lenses for working with a computer are attached to glasses for constant wear.
The anti-reflective coating of spectacle glasses can significantly reduce the irritating effect of bright light and glare on your eyes. Yellow-orange coating is recommended for use in rooms illuminated by fluorescent lamps. This filter delays the rays of the blue spectrum, which not only make it difficult to focus the eye, but also have a harmful effect on the retina.
