If your looking at a screen all the time, or a cell phone. Get some blue light filter glasses. Help reduce the strain on your eyes. Wife works 8-10 hours a day looking at a PC screen.

Hey... I'm 34 and I had to go get my eyes checked and start wearing a low prescription this year. Almost overnight I noticed seeing street signs became more difficult. I was almost right under them before I could actually read them. I was finding my eyes straining to focus. Reading a tape measure turned into looking two and three times to make sure I actually saw what I saw.

My age, But I been needing to wear glasses for 20+ years. I just never really do, hate constantly cleaning lenses. Cant put my finger close to my eyes for contacts. But not wearing them causes straining. Some vitamins help. I did see a improvement. But forgot to take them for awhile and a decrease in eye health. So I'm going back to taking them.

But Ive been wearing RX shooting glasses for the last year. Which improved my Iron sight shooting greatly. I stain alot shooting airguns because the targets are smaller.
