Why is there a need for eyeglasses while working on laptops/screens?

Eyeglasses have become a fashion accessory these days, haven’t they? There were times when people who wore glasses were looked down upon but in today’s world people like to flaunt the different types of frames.
But do you know? Every eyeglass does not solve the same purpose. Most people feel that if they do not have a power, they do not require glasses even if they have to work on their laptops all day.

What they don’t realize is that not all glasses are same. Computer glasses differ from regular glasses, they are specifically made to reduce the strain on eyes associated with computer work. A person works on the laptop/screens six to eight hours a day on an average and gets accustomed to the fact that his eyes just feel tired and irritated at the end of the day. The symptoms of strained eyes include eye discomfort, difficulty in focusing, watery eyes, dry eyes, blurred or double vision, increases sensitivity to light, tired or burning eyes and a headache. This is often associated with Computer Vision Syndrome. If you are experiencing these symptoms, its time you should visit your optometrist.
After 40, a person’s close up vision becomes less clear because of presbyopia, this age-related loss of natural focusing power affects reading and seeing a smartphone or computer vision clearly and comfortably. Bifocals can provide clear distance and near vision, but an intermediate vision (needed for computer use and seeing your smartphone) often remains a problem. And progressive lenses or trifocals, though they offer some help for intermediate vision, often don't have a large enough intermediate zone for comfortable computer work.
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.

Thanks to modern technology, we have a cure for this. The computer glasses have come to our rescue. Computer glasses are special-purpose eyeglasses meant to optimize your eyesight when you're looking at digital screens. These glasses have an anti-reflection coating that helps to reduce the glare that bounces off the screen and the light coming from the screen. The brightness of the screen causes the eyes to feel strained. This allows you to see clearly and without having to squint when it comes to using a laptop screen so your eyes are more comfortable. Generally, computer glasses have about 60 percent the magnifying power of reading glasses. But the optimal magnification depends on how far you prefer to sit from your computer screen and how close you like to hold your digital devices. Computer glasses also should accurately correct any astigmatism you might have, and precise measurements should be taken to ensure the optical centre of each lens is directly in front of your pupils when you are using your preferred working distance. For these reasons, computer glasses should be customized to your individual needs. Using weaker, non-prescription reading glasses for computer work and seeing your digital devices typically won't provide the accurate vision correction you need for sustained clarity and comfort.
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.

So if you are experiencing these symptoms or are worried about your eye health, its time you visit your optometrist on an urgent basis so that he can help you with taking care of your precious eyes.
