I’m trying to get smarter (be less of an idiot) about my computer use, which I blame for some mild astigmatism I picked up in 2020. Since I’ve been doing all my work from home, on a laptop screen, I’ve picked up bad habits. I really favor keeping the computer on my right hand side, which is apparently a bad idea. People on the forum and in the scientific world have noticed that spending a long time looking at screens or papers from an odd angle tends to produce astigmatism in predictable ways (the eye that looks across the mid-line gets worse faster.)
I’m not able to hold or work on my computer and get it to blur distance (arms are too short) so I’m stuck with a lot of accommodation whenever I work on my laptop (because it’s much closer to me than the beginning of blur). In addition to taking breaks and getting outdoor time and all the important things for eye health I’m trying various strengths of plus lenses to so that I’m doing less accommodation or at least the focal length is different.
Using the poor-man’s version of these similar to the lens on the left
I got my first ever pair of multi-focal computer glasses today ($7 for three pairs) and they’re kind of interesting. If I move the computer out of the sweet-spot of the mutifocals it becomes unviewable. When I tilt my head a little bit it becomes un-viewable. I’m realizing that I unconsciously tilt my head a lot, and move the computer over to my favorite (bad) spot a lot. So it’s kind of eye-opening to promote awareness of my bad habits. Even though the 3 pairs of multifocals are supposed to have the same power they’re all a little bit different, which I guess is what one should expect in the $2-3 price range. For the money they’re great, going to cycle through the various plus lenses throughout the day when on the computer or phone (along with no lenses) and see if mixing it up a little bit and being forced into different viewing angles and postures takes off some of the strain. If nothing else it’s forcing me to stop sliding the computer over to the right which is my old bad habit. I also can’t look at the screen at an angle anymore, which I guess I did all the time without realizing it.
