After putting up with neck-aches and muscular-tension headaches for some time, I got from my optometrist a pair of single-focus, full lens glasses. We discussed the problem, and since I said that the distance from my eyes to the screen, to the desk where copy lay, and to the keyboard are much the same, he provided lenses that had a mid-focus of about 2ft (60cm). They work just fine. It *is* a bit of a nuisance to have to replace them with other glasses for longer distance, but I can read OK with them, except for very fine print. Mainly I keep them in their case on the computer desk. On the point of ergonomics, the relationship between screen-height, chair height, and keyboard height is a very important one. The centre of the screen, according to most authorities, should be a little below eye-level. But as more and more 17" and 20" screens come onto the market, I find from my experience in consulting that the best results are obtained if the TOP of the screen is at, or a little below, eye-level. Having to bend the head back, in order to look up to see part of the screen will stress the shoulder and neck muscles, eventually leading to strain, and, if maintained for any length of time, tension headaches. Tilting the head back also can cause unconsciousness, due to compression of nerves and blood vessels at the back of the neck. The keyboard should be in such a position that the wrists are straight, or bent down, rather than bent upwards, as this can cause wrist strain and RSI. The chair should support you with your back straight, and the seat should be of such a height that your feet are on the floor, not dangling, while your thighs should be supported and straight, neither bent up or down. Above all, and this is most important for PWPs, especially those of us who get into a "fugue", take a break completely away from the computer for at least 15 mins every two hours, stand up, and walk around, even leave the room. And I mean a break, not playing a computer game, or just changing tasks. Sorry if I am preaching, but we have enough trouble without making more for ourselves! <grin> Jim
