I purchased cheap glasses online and intentionally turned down the astigmatism correction. Significantly reduced eye strain.
* During the day, I use my "correct" prescription. Even though it gives me a bit of eye strain.
* At night, I switch to my adjusted prescription. Not as visibly clear, but significantly less eye strains.
It's nice having a clear separation between "focus" glasses and "relaxing" glasses.
So I budget $100-200 from my HSA per year for glasses, and have spares at home, the office, and in the car. When they're 5-6 years old, I donate them to a charity that redistributes them.
Not "tiny" I guess, but surprising luxury for $16/month.
I'm so near-sighted that I need my glasses to see the screen, but just barely. In some situations I can take my glasses off to work and it makes such a difference - there's no strain at all.
