Computer Glasses

When you work at a computer for any length of time, it is common to experience eyestrain, blurred vision and other symptoms of computer vision syndrome (CVS). Viewing computer-generated print and images on a screen or monitor for prolonged periods is harder on the eyes than viewing a similar amount of material on the printed pages of a book or magazine. If your eyes feel strained after prolonged computer use you should schedule a comprehensive eye exam to determine the cause. If you’re under age forty, blurred vision during computer use may be due to your eyes being unable to remain accurately focused on your screen for sustained periods. Or you may have a hard time quickly and accurately changing focus, such as when you shift your gaze from your monitor to your keyboard and back again. This problem, called lag of accommodation, can cause eyestrain and headaches — two common symptoms of CVS.

A comfortable fitting spectacle frame defines ultimate customer satisfaction. The process starts with selecting a frame with adequate dimensions, which will allow manipulation and adjustments, once the lenses have been fitted.

Ears are usually not positioned exactly at the same height. One ear may be higher or lower than the other. The bridge of the nose may be relatively high or low in relation to the eyes. A head may require very long temples (side pieces) or very short ones. The position of the ear, where the temple sits in relation to the place where the frame sits on the nose, can hugely influence the fit and optics of spectacles. It’s very important that the optical dispenser takes note of all these features and selects a frame that can be fitted to overcome them.

The mystical, magical multifocal lens

Word of mouth can be very powerful, in a positive and especially in a negative way. People often talk about how wonderful something is, but if it didn’t work for them, they become much more inclined to steer others away from it. When your optometrist prescribes multifocal lenses for the first time, it’s natural to feel a little anxious. You may ask: how does it work, why do I need it, will I adapt to it, or will I like it? You may even know someone (or be married to someone) who couldn’t adjust to these lenses at all.
