Hi TJJ. You mentioned that you started getting these eye strain since 2-3 years ago. Were you able to use laptops and iphone for long periods of time without any problems before that? Did you change your laptop or monitor or PC around 2-3 years ago, when you first started having these eye strain?
I am glad you have found a "cure" through this restatis. Do you need to take this medicine everyday to eliminate the eye strain? I mean if you stop taking this medicine, do the eye strain come back?
I suffer from eye strain due to PWM flickering and intel graphics driver. And I cant use many/most laptops and even iPhones, they give me eye strain. Medicine or not, I think you should find out the cause of your eye strain, and see if PWM or graphics driver is causing you eye strain or not. If indeed that PWM is the reason that is causing you eye strain, you should find a laptop/display that does not have PWM, otherwise the source of your eye strain is still there, and you are looking at a PWM display everyday and you may need that medicine to continuously treat your condition. Just a suggestion.
