See a real optometrist and/or ophthalmologist.

Good monitors, at the right distance for your eyes (& glasses).

If you're expecting your eyes to perform like they did way back when, when you were ~20, develop realistic expectations.

For years my optometrist told me I would get presbyopia eventually, around 50 it really happened to me. Now I have a pair of distance glasses and a pair of reading glasses. It can be a hassle to pack an extra pair and change lenses but I have good vision for everything I do.
