About NeoVista
I started this site because I spend 10+ hours a day on screens and my eyes were paying for it. Headaches at the end of every workday, dry eyes by mid-afternoon, trouble focusing on anything past arm's length after a long session.
So I started reading the research. Not the clickbait health articles, but the actual published studies on digital eye strain, blue light exposure, and preventive eye care. I combined that with my own trial-and-error over the past few years and wrote it all down here.
Nothing on this site replaces a visit to your eye doctor. But if you want to understand what is happening to your eyes during those long screen sessions and what you can do about it today, this is a good place to start.
