See, the regular glasses you wear don't really provide the accurate vision correction for the distances typical in computer work.They are either for close or distant seeing. In order to see clearly, many resort to the methods of leaning toward the screen or looking down through the bottom part of their lenses. Such mis-position in working usually lead to eyestrain, dry eyes, headaches and blurred visions. With computer glasses, because the powers are particularly adjusted for the computer vision distances, there is no need to adjust the sitting position in order to see. For those who spend a significant amount of time working with a computer, nothing is better than one pair of such glasses that will provide them good vision and comfort at the same time.
