I agree, though I have not retired yet, and wear bifocals. I use computers both at work and at home and am convinced that there is no inherent cause of eyestrain in the fact that a monitor is backlit etc. The secret is to have the screen at or below eye level and well away from your eyes (at least 80 cm) to avoid your eyes having to look upowards and accommodate (i.e. so that you are focused on infinity and your eye's lens does not have to contract). I suspect that short rests, which one tends to take anyway in order to get a cup of coffee etc., are also helpful. I find that eye strain happens when I just push the envelope too far in terms of staying up late, and I could be watching TV, reading a treaditional book etc, just as easily as working on the computer.
Another tendency I reject is the idea that you need to put a filter screen in front of the monitor. This is a recipe for eyestrain if anything, as it makes the screen dimmer. Many people who complain of eyestrain from bright sources do not realise how very much brighter ordinary daylight is than most artificial light sources, and make do with poor lighting.
