I found this website only less than an year ago, when my eye-strain troubles restarted really bad after changing job/computer. It does not mean my visual experience in front of electronic devices has always been good earlier. I had just gotten desperate with searching for the "truth" which never came, and had been lucky to find an hardware/software compromise to hang on to. If I recall, I "got" here accidentally because I had more than a feeling my eyestrain depended on the type of graphic card, although all the experts I talked to, like computer admins at work, would tell me it was fantasy. I am sure there are many people out there who are desperate too, have no clue why they suffer from eyestrain and have stopped looking for a reason / do not have enough know-how to identify the culprit.
To be honest I feel ashamed to have realized in a more substantial way only recently, that my eyestrain and many of my headaches have been caused by newer forms of ceiling lighting and lamps. It was not my imagination nor a psychological effect nor stress nor dry eyes, as many doctors told me.
Still now I am very frustrated. I learnt a lot of things but a permanent solution, hardware-software wise or medical-wise, appears a chimera.
