I wear photo gray glasses (or whatever they call it now) with a UV coating, and sunglasses when i drive (against eye fatigue, the windshield already has UV coating).
1. Increase the font size. Starting with having a zoom of 150%+ on most websites. For example, on HN its 170% and on Reddit its 150%. On Visual Studio Code, I started using 18px as the editor font size.
2. Night Light on Windows 10 and low blue light mode on monitor. It sucks on some websites, but I am used to it now.
3. Blue light filter on my Glasses. This is recent and it seems to help.
4. Simple eye exercises and 20-20-20 rule for eyes.
- 20 times a day
- look and blink 20 times
- at 20 different distances
- at least 20 feet away
