The Creation of Computer Glasses
With the advancement of technology and the proliferation of the personal computers, youths and adults alike are spending more time in front of a computer than ever before. Many is required to do so for work, while some use the personal computer to manage bills and other domestic tasks. This increased exposure to the computer screen created a new kind of condition called the Computer Vision Syndrome (CVS). Symptoms of CVS includes headaches, blurred vision, neck pain, redness in the eyes, fatigue, eye strain and dry, irritated eyes among many others. To help combat CVS, a new category of glasses is created and they are none other than the Computer Glasses, also commonly known as the Computer Reading Glasses.
Computer Glasses works by correcting an individual’s intermediate vision, which is around 20-30 inches from the individual’s eyes. This distance is traditionally ignored by both reading glasses, which corrects an individual’s near vision and the driving glasses, which corrects an individual’s far vision.
Types of Computer Glasses
There is in general 3 types of computer glasses:-
Single Vision Computer Glasses- This is the most basic kind of computer glasses and as the entire lens power is prescribed to give the most comfortable vision at the screen. The downside of these lenses is that both near and far vision will be blurry.
Traditional Bifocal Computer Glasses- This kind of computer glasses has lenses that are divided into 2 sections. The bifocal lens will provide comfortable intermediate vision at the majority of the lens while the lower portion of the lens will provide comfortable near vision for reading materials.
Progressive Focus Computer Glasses- The most advanced type of computer glasses have a progressively focused lens that correct distant, intermediate and near vision. However, the majority of the lens will be focused for intermediate vision which renders them unsuitable for driving and general purpose use.
All of the above computer glasses can also have some anti-reflective coating, also called anti-glare coating applied to further increase viewing comfort.
Do You Need Computer Glasses?
As a rule of thumb, if an individual spend more than a few hours at a time in front of a computer, they will benefit from computer glasses. If they suffer from any of the symptoms of CVS listed above, such as blurred vision, neck pain, then the benefits of a pair of computer glasses will increase exponentially.
Where can you get Computer Glasses?
Computer glasses can be an expensive investment but they are well worth their price in gold as they protect one of your most valuable assets- your eyes. Therefore, do not be tempted to buy regular reading glasses for use as computer glasses.
To get your very own personalized pair of computer glasses, simply measure the distance between your nose bridge to the screen of the computer and bring the measurement along when you visit your optician to get the optimal lens power for your computer glasses.
