There you go, I just saved you at least £70. Eye strain just isn't the problem it was back when we were all using CRT monitors (which pulsed on and off constantly, which caused headaches). Also make sure your room gets enough natural light in general, sit upright, get a cuppa tea or a glass of water every hour or so.
There is literally no point giving your money away instead of doing stuff humans should be doing anyway.
