Ask HN: Did My Eyesight Improve?

Ever since I saw this other HN post [1], and this speech on Myopia [2], I've been experimenting with trying to improve my eyesight. Primarily, I've been taking off my glasses when working at the computer throughout the day and placing my monitors so that they just begin to become blurry but are still readable. I also purchased glasses with sphere slightly less than my prescription. I began experimenting shortly after the last visits to the optometrist mid-2022. I went to the optometrist yesterday, and my sphere did decrease in both eyes, but I'm having a difficult time of telling whether my eyesight actually improved since the astigmatism numbers changed as well. Additionally, these are all different optometrists, and I went in the morning this year instead of in the afternoon after working on a computer all day in the previous years. Could you help me interpret this data? Did my eyesight improve?
