Most of all, computer glasses, like other reading glasses, enable wearers to use the machine which carries the words and expressions handily and conveniently. Without computer glasses, they are forced to put their nude eyes directly and closely to the screen in order to see what are presented on the screen. This is detrimental to their eyesight in that they are seriously exposed to the radiation which is fatal to the health. However, if they choose a right pair of computer glasses, even in a long distance, they can still spot the interesting news or film lines without troubles.
What’s more, computer glasses, just as I have mentioned above, are anti-radiation eyewears apart from helping us to see the objects clearly. Radiation, which has been proven harmful by the scientists, affects us directly and indirectly. From a direct way, when we use any electric appliance, such as oven and laptop, we are endangered by invisible poison which will cause grave illness. And from the indirect way, radiation is everywhere – we live in a world of radiation and cannot escape but to stay to face the music. At this time, all we need is a pair of computer glasses.
Last but not the least; do computer glasses mean cheap glasses? I guess to some extent my answer is yes. Because computer glasses, with the development of the Internet, become more and more acceptable recently. So they are more approachable to computer glasses when comparing to the ear when computer glasses are rare. Therefore, computer glasses in nature are cheap if correct choice is made.
To sum up, computer glasses are functional in two aspects. If you are a myopia and radiation phobia, just buy a pair of computer glasses to protect you from two dreadful matters.
