The glasses reduce the glare and make it easier to look at the screen for a long time. Computer screens cause a strain on the eye because they are placed at a distance of 20 to 26 inches from the user's eyes.
Many people end up with blurry vision, headaches, and eye strain. Computer lenses give users a wide field of view, prevent excessive focusing efforts, and prevent unhealthy postures. It relieves the digital eye strain and blocks the blue light from the screen.
Digital eye strain causes eye fatigue, blurred vision, double vision, red eyes, eye twitching, and headaches. It even causes neck and shoulder pain in some people. The blue light from the computer screen affects the circadian rhythm and causes damage to the retinal cells.
Computer spectacles have lenses that filter out the blue light to reduce the amount of blue light entering the eye.
Features of a computer glass
Anti-reflective coating
The anti-reflective coating in the glasses reduces the glare from the screen and other light sources. More light to pass through the glasses to provide a sharp and clear vision. When the vision is sharp and clear, it reduces eye fatigue and eye strain in people who use a computer for a long time. The anti-reflective coating makes the lenses almost invisible and attractive.
Color tints
The color tints in computer glasses increase the contrast and filter the uncomfortable harsh light to relax the eye muscles. Brown and amber-tinted glasses block out blue light and reduce glare, and yellow tints help to improve the contrast.
The tint helps to reduce eye strain. Amber and yellow hues absorb the blue light before it reaches the eyes. It reduces the digital eye strain and does not disturb the sleep pattern.
Types of computer glasses
Monofocal: Monofocal glasses provide optical correction for the distance between the screen and the user's eyes. The user can view the entire screen with minimum up and down head movement. Objects at a distance and reading material closer than the computer screen appear blurry.
Bifocal: The bifocal glasses have two segments. The upper segment is set up for computer screen distance, and the lower part is set up for reading distance or distance closer than the screen. Objects that are at a distance farther than the screen appear blurry. The images in the peripheral zone of vision are distorted. More up and down movements of the head are needed to view all parts of the screen.
Trifocal: Trifocal glasses have three segments. One segment is for objects at a distance, another for objects closer to the computer screen, and the third is for vision at screen distance. There may be limitations in viewing some areas as the images may appear distorted.
Progressive addition lenses: The segments in progressive addition lenses change gradually to ensure that the user has a smooth and uninterrupted vision without any visible line of demarcation. This no-line multifocal lens helps to view distant and close objects well by providing a gradual transition in strength from top to bottom.
Computer glasses in Kenya help people work comfortably on computers for a long time without straining their eyes. One type of computer glass cannot fit everyone. Before buying computer spectacles, users must consider their visual ability, type of work, the distance between the user's eye and screen, lighting, and personal preferences.
The optometrist and ophthalmologist help people to choose the right glasses. People can work comfortably without worrying about eye fatigue and eye strain with computer glasses.
