Computer glasses: Relieving computer eye strain
When you work at a computer for any length of time, it's common to experience eye strain, blurred vision, red eyes and other symptoms of computer vision syndrome (CVS). This is because the visual demands of computer work are unlike those associated with most other activities.
What can you do? For starters, have a comprehensive eye exam to rule out vision problems and update your eyeglasses prescription. Studies show that even small inaccuracies in your prescription lenses can contribute to computer vision problems.
If your glasses are up-to-date (or you don't need prescription eyewear for most tasks) and you continue to experience eye discomfort during computer work, consider purchasing computer glasses. These special-purpose glasses are prescribed specifically to reduce eye strain and give you the most comfortable vision possible at your computer.
Why computer glasses?
Computer screens usually are positioned 20 to 26 inches from the user's eyes. This is considered the intermediate zone of vision — closer than driving ("distance") vision, but farther away than reading ("near") vision.
Children and young adults who need prescription eyeglasses usually are prescribed single vision lenses. These lenses correct the wearer's nearsightedness, farsightedness and/or astigmatism, and the shape of the lens inside the eye automatically adjusts to provide the extra magnifying power required for computer vision and near vision.
Without computer eyeglasses, many computer users often end up with blurred vision, eye strain, and headaches — the hallmark symptoms of computer vision syndrome. Worse still, many people try to compensate for their blurred vision by leaning forward, or by tipping their head to look through the bottom portion of their glasses. Both of these actions can result in a sore neck, sore shoulders and a sore back.
Computer glasses put the optimum lens power for viewing your computer screen right where you need it for a clear, wide field of view without the need for excessive focusing effort or unhealthful postures. University research also shows custom computer eyewear can significantly increase worker productivity.
Lens designs for computer eyewear
Many special purpose lens designs work well for computer glasses. Because these lenses are prescribed specifically for computer use, they are not suitable for driving or general purpose wear.
The simplest computer glasses have single vision lenses with a modified lens power prescribed to give the most comfortable vision at the user's computer screen. This lens power relaxes the amount of accommodation required to keep objects in focus at the distance of the computer screen and provides the largest field of view.
Single vision computer glasses reduce the risk of eye strain, blurred vision and unnatural posture that can cause neck and back pain, and can be used comfortably by young and old computer users alike.
Lens coatings and tints
For maximum viewing comfort, the lenses of your computer glasses should include anti-reflective coating. Sometimes called anti-glare treatment, anti-reflective (AR) coating eliminates reflections of light from the front and back surfaces of your lenses that can cause eye strain.
Also, computer glasses with photochromic lenses can shield your eyes from potentially harmful high-energy visible blue light from your computer screen and digital devices — and automatically darken in sunlight outdoors, too.
Where to buy computer glasses
Cyxus blue light filter lens is designed using the American HEV-Adsorb Lens technology. HEV-Absorb blue blocker lenses are made with a special blue-light blocking polymer, that is directly incorporated into the lens materials. That means the blue- blocking technology won't chip or wear away. By absorbing blue light, this polymer prevents blue light from passing through the lens to your eye. In a word, It can absorb high-energy blue light, UVA, UVB, and filter harmful Blue Light, which can lead to eye strain and headaches.
Cyxus makes efforts to create more ideal products, integrate the latest technology with 100% user satisfaction. Cyxus not only produces glasses but also bring you the enjoyment of digital life. See the wonderful world, start with your Cyxus eyewear.
