Most people spend at least some time looking at an electronic device for at least part of the day. Looking at these screens can cause problems for our eyes. Studies have shown that 90 percent of computer users have suffered from computer vision syndrome at some point in their lives.
Symptoms of computer vision syndrome include blurred vision, dry eyes, eye strain, eye irritation, headaches, and neck and back pain. There are a number of factors that cause these symptoms including how far away the electronic device is, and inadequate lighting. The American Optometric Association recommends taking breaks on the computer. Those who use their computer for work might not have that chance. They might benefit from computer glasses. If you are curious to try computer glasses here is more about what they do, and how they might be helpful.
Computer glasses are glasses specially designed to use when working with a computer. The lenses in these glasses are more powerful than other glasses, so they are not appropriate to wear while driving or doing other activities. Computer glasses work by reducing glare and providing a wider field of vision.
Computer glasses come in three different types. Singal vision glasses are for anyone that uses the computer. The glasses reduce eye strain and blurry vision. The glasses also help with bad posture because you won’t have to lean forward or sit at an awkward angle to see the screen. Occupational progressive lenses work to improve intermediate and near vision. The intermediate area is larger than in regular glasses making the ability to see in the distance smaller. There are also bifocal and trifocal lenses that work like regular bifocal glasses except with a larger area for the near and intermediate field of view.
Computer glasses also are coated with two special coatings, anti-glare and anti-reflective. The coatings help to reduce the light glare which contributes to eye strain. Some glasses are tinted to help reduce glare even more and to filter out blue light.
Blue light is the light emitted from most electronic devices. Blue light is thought to cause eye strain. Blue light also effects on the rhythm of our body causing sleeping issues when viewed in the evenings or night time. Studies have shown that sleep issues can lead to bigger issues such as obesity, and diabetes. A Harvard study put ten people on a schedule that shifted their circadian rhythm. The shift affected their blood sugar putting them in a pre-diabetic state.
In a study by the University of Alabama School Of Optometry, there was a direct correlation between how well someone’s vision was and how productive they were on the computer. The study showed those who even have slight eye problems had a reduction in speed, and productivity. It is why those who work for long hours on the computer could benefit from an eye exam and a pair of computer glasses. The glasses not only help you see the computer better than normal glasses might but also helps cut down on glare and harmful blue light emissions.
