Wee to the world of accessibility. Ive been a software engineer for 35 years. And I have low vision. Eye strain has been an ever-present problem for me. Fortunately in 216 there are excellent solutions to eye strain. Eye strain does not damage italic your eyes. It just makes them tired. Looking straight into the sun damages your eyes. Shooting a laser into your eye damages it. Don do those things. Go ahead and use theputer. Nobody has perfect vision. The lenses of our eyes are living structures not hard glass ground to quarter-wave tolerances. Everyone is a little near- or far-sighted or has slight astigmatism. If your eyes are getting tired go to an optometrist and ask for a set of prescriptionputer glasses. They will fix whatever slight problem you have. Even if you don need glasses for other purposes it can make a big difference when using theputer or reading. Sometimes your eyes are tired and red because theyre dry. You aren bing enough when you are in front of aputer all day. You can try taking a break for a few minutes every hour. B or close your eyes. Go to the restroom and splash water in your eyes. Get up and walk around while youre at it. If you aren the kind of person who can bear to take breaks get some artificial tears eye drops. If you don like the first kind you buy try the name-brand ones. This is another place where sometimes more expensive actually means better. I second the rmendation for . It turns down the blues of your monitor at night which makes it easier on your tired eyes. Less blues also lets you go to sleep better when youre finally done with theputer. Too much blue light signals daytime to your pineal gland inhibiting release of melatonin. PCs are soooo much more accessible these days than they were in the days of Windows 3.1. And Win 3.1 was better than a VT1 terminal I can assure you.
