When working on a computer for an extended period of time, most of us often experience eye strain, blurred vision, red eyes and other symptoms of computer vision syndrome (CVS). This is because the visual requirements for computer work are fundamentally different from those related to most other activities. That’s why most people working long hours in front of the video display prefer to wear computer glasses. Computer goggles are specifically designed to improve and reduce the tension you may experience at the end of the working day.
Who and Why Needs Computer Spectacles?
If you are under the age of 40, eye strain or blurred vision while working with a computer may be due to the inability of your eyes to remain focused on the screen, or because your eyes have trouble changing the focus from the keyboard to the screen and back for extended periods of time. These focusing issues are often associated with CVS and can be corrected with computer glasses.
If you are over 40 years of age, the problem may be due to the occurrence of presbyopia – the normal age-related loss of ability to see at near sight of the eyes. This can also be caused by the symptoms of computer vision.
If your glasses are up to date (or you do not need glasses to perform most everyday tasks) and you continue to experience discomfort during computer work, consider purchasing customized computer glasses. These computer glasses with special purpose lens are specifically prescribed to reduce eye strain and give you the best view of your computer.
Benefits of the Computer Glasses
Less Eye Strain
Less Burining eyes
Less Red eyes
Effective Eyes Protection
Blue Light Protection
UV Light Protection
Anti Reflective & Glare
All of us who are constantly working with video displays – computers, laptops, tablets, mobile phones, and even flat-screen TVs, notice that our eyes are often tense and irritated throughout the day. Computer vision syndrome is the result of the high visual requirements for computer work. This condition (CVS) is due to the light emitted by the computer screen and focusing on the artificially illuminated display for long periods of time without proper eye protection.
Each of us blinks with eyes from 12 to 15 times per minute, but when you are in front of the computer screen, this number drops dramatically to 3 to 4 times per minute. All this allows our eyes to fatigue more easily.
If you blink 5 times less this might have serious impact on your eyes. When blinking, your eyes are getting lubricated by the tears and your eyes are being moistured. When focusing in a video display, your eyes are being moistured 5 times less and thus your eyes get more tired, you feel dryness and headaches become part of your everyday life. Protecting your eyes with specialized computer glasses can significantly decrease the symptoms of CVS (Computer Vision Syndrom)

Why Computer Glasses are important?
Computer glasses differ from ordinary glasses or reading glasses for a few main reasons. This is in order to optimize your vision when viewing your computer screen for a longer time. In our busy digital daily life, each of us spends at least 10 hours in front of some kind of monitor – a computer, a laptop, a tablet, a smart phone.
Eyezen + is one of the latest lenses designed to optimize vision and comfort when using digital devices. According to Essilor, the lens filters at least 20 percent of the blue light, but unlike other lenses with blue light filters, it ensures clear vision without being colored. Available as with a PC-free glasses and a diopter computer glasses.
Electronic screens (Video Displays) are typically located 50 to 70 centimeters from the eyes of the user. This is considered to be an intermediate zone of vision, closer to vision (“distant”), but further away from sight (near vision).
Children and youngsters who need prescription glasses usually get glasses for a distance. These lenses correlate Nearsightedness, Hypermetropia and / or Astigmatism, and the shape of the lens inside the eye is automatically adjusted to provide additional magnification needed for computer vision and close vision.
When a person’s near vision becomes less clear due to presbyopia after the age of 40, this loss of natural focusing energy associated with age affects reading and seeing a smartphone or computer vision and comfort. Bifocal glasses can provide clear vision at a near and distant distance, but intermediate vision (necessary for computer use and seeing your smartphone) often remains a problem. Progressive lenses or trifocal spectacle lenses offer some help for intermediate vision, but often do not have a large enough intermediate area for convenient computer work. So many people resort to a pair of computer glasses to reduce tension in their eyes.
Without computer glasses, many computer users often end up with blurred vision, eye strain, headaches, red eyes or fatigue – the distinctive symptoms of computer vision syndrome. Worse yet, many people try to compensate for their blurred vision by leaning forward or tilting their heads to see through the bottom of their glasses. Both actions can cause problems with both the eyes and the overall posture, neck, shoulders and back.
MEN`s Computer Glasses
Typically, computer glasses have about 60% of the increasing power of reading glasses, but they are very often without a diopter and have filters for Blue light, Anti-reflection coating and UV filters. But the optimal zoom depends on where you prefer to sit from your computer screen and how close you want to keep your digital devices.
Computer glasses should also accurately correct the astigmatism you may have and take precise measurements to ensure that the optical center of each lens is right in front of your pupil when using the preferred working distance.
For these reasons, computer glasses need to be personalized to your individual needs. Using less prescription reading glasses for computer work and seeing your digital devices will usually not provide you with the exact correction of vision you need for constant clarity and comfort.
Types of lens design for computer glasses
Many designs of special purpose lenses work well for computer glasses. Since these lenses are specifically designed for use by a computer user, they are not suitable for driving or versatile wear in everyday life.
Computer vision syndrome causes eye fatigue, which can make you feel tired and incapacitated in general.
The simplest computer glasses have single-lens lenses with modified lens power prescribed to provide the most comfortable view on the user’s computer screen. This glass power reduces the viewing fatigue and improves the keeping of focus objects at a distance from the computer screen and provides the widest field of view.
Another popular eyewear lens design is the professional progressive lens – multifocal, no lines that corrects visual, intermediate and point vision.
Progressive Progressive Lenses have a larger interstitial area than regular progressive lenses for a more comfortable viewing of the computer. But it leaves less space on the lens for remote viewing, so these lenses are not recommended for driving or other important distance viewing tasks.
Other lenses used for computer glasses include professional bifocal and trifocal lenses. These lined multifocal lenses have larger zones for intermediate and close vision than ordinary bifocals and trifocals, and the location of the intermediate and adjacent areas can be customized for your computer vision needs.
Coatings, shades and filters of the computer glasses lenses
For maximum viewing comfort, computer glasses should include an anti-reflection coating. Sometimes called antireflection coating, antireflective (AR) coatings remove the reflection of light from the front and rear surfaces of the glasses, which can cause eye strain.
Some opticians recommend adding a light shade to computer glasses to reduce the glare caused by raw artificial lighting and to improve contrast. Tinted glasses for computer glasses are also recommended to block short waves, “blue” light emitted by computer screens, which is associated with glare and eye strain.
