Eye Health For Computer Users

Saturday, March 28th, 2009

In the years since we exchanged our slide rules for calculators, more and more of us use computers for longer periods each day. This raises questions about eye health and the VDU screen, so if you are worried about the hours you spend slaving over your keyboard, read on…..

Problems can arise because of the amount of time we spend in front of our computers. To counteract this you need to do a spot of eye exercise and remember to blink often, which moistens the surface of the eye, and try to get into the habit of looking away from the screen at regular intervals. This alters your focus and helps to prevent eye strain and fatigue.

You may need prescription glasses for the computer, and if so, an anti-reflection coating will help to reduce the effects of glare. You should also make sure that the glasses you are wearing are at the correct focal length. Tell your optician how far away the screen is when you work.

Have regular eye tests with a qualified optician and make sure your prescription glasses are up to date. If you spend most of your working day on a computer your employer will pay for the test, and the cost of the spectacle lenses. Buy glasses online and you can afford a few pairs, so you’re never straining to see the screen without them.

Stay Safe At Night

Do you ever feel worried about driving at night?
Do headlights dazzle you?
Do you feel your vision is worse after dark?
If the answer to any of these questions is yes, then you should think about having an anti-reflection coating on your prescription glasses.

The first thing to do is to have an eye examination and make sure your glasses prescription is up to date. The optician will also check the health of your eyes to make sure there are no underlying problems.

You then need to choose lenses which have an anti-reflection coating on them. This is not the same as a tint, it is a colourless coating which blocks reflections and allows all available light through to your eyes. This means that your vision is clearer and you are as safe as you can be when driving.

The coating is also useful if you use a VDU, as in cutting glare it cuts down on eye strain too. People looking at you see through your lenses too, as the lenses not only enable you to see more clearly, they look almost invisible when in the eyeglass frames.

If your glasses do have tinted lenses your Optician will tell you if they can be worn for night driving. You should never wear anything but the lightest tint when night driving, it’s not safe and is also illegal. You could be endangering yourself and others if you wear incorrect lenses or tints.
