Oops, sorry, I've only now remembered to answer this...if you do a search you will find lots of info about 'computer glasses' and hyperbole about 'Computer Vision Syndrome'. In many ways I think optometrists have found another 'niche' to sell glasses to :lol: All I know is that my +1.0 non-prescription 'computer glasses', similar to these ones with a very light sepia tint do make a difference if I have to read a lot on the screen.
I'm so grateful that so far I don't need expensive prescription glasses!
