Computer Vision Syndrome (CVS) is commonly seen in persons working on computers for long hours. The symptoms of Computer Vision Syndrome involve not only the eyes but also the musculoskeletal system.
Eye problems consist of:
Working on computers, watching TV and driving a vehicle are strenuous jobs for our eyes. In all these situations the object of focus keeps moving from one position to other. Hence eyes have to move constantly to keep the object at the centre of the retina. Uncorrected refractive errors are the single most important factors that trigger off this disorder. Hence even a small refractive error need correction.
The placement of monitor is neither like a book in your hand nor like a long distance object. Hence both the segments of your bifocals will be of no use on computers. Either you choose multifocal glasses or get computer glasses. Older reading glasses may prove to be more comfortable than the recently changed ones.
Not really. If the fitting of the contact lenses is perfect and refractive error is completely eliminated, they should prove to be as comfortable as glasses. Sometimes, in an overenthusiastic move to use only contact lenses and not glasses, astigmatic errors are left unattended. In such cases, glasses should be preferred over contact lenses. Also if one has a little dryness in the eyes, contact lenses may add to the discomfort.
Tears are constantly secreted in our eyes to keep the front surface of the eye wet. This wetness of front surface is absolutely essential for clear and comfortable vision. If there is tear deficiency, it will cause dry eyes and lead to CVS. Also due to extreme concentration, the blinking rate usually decreases. Hence tears dry up faster leading to a to false dry eye state. Such cases can be helped by artificial tears, available as Eye Drops. One should also try and blink as normally as possible.
