I’m digging into an idea around eyeglasses, screen-time, and vision discomfort. If you wear prescription glasses but still get headaches, eye strain, or blurry vision after long screen days, I’d love to chat briefly (20–30 min).

Pure research, zero selling.

Interested? Drop a comment below or email me directly at jbornhorst [at] gmail.com. I’ll coordinate a convenient time to talk.

Yes, I'm very nearsighted. I've worn progressive lenses for years but they continue to drive me crazy. I can see fine with them, but my eyes easily get fatigued and I have to take long breaks to get them to calm down.

Over the summer I added a pair of progressive occupational lenses (not reading glasses). They are focused arms length in front of me. This has been a complete game changer. I can now see my monitor crisply, clearly, and easily in a way that I haven't seen it in a decade.

When I swap back and forth between my regular lenses and my occupational lenses, the difference is stark. With my regular lenses there's a part of the screen that's about a half dollar coin in size that's clear and in focus. The rest of the screen is every so slightly blurry. I have to move my head to constantly adjust the focal point, or move my eyes and struggle to focus.

When I switch to my occupational lenses, the entire screen is clear. I don't have to move my head. I don't have to fight to focus. Where I look, it's crisp.

No wonder I was struggling! I was fighting to focus all day long. I suffer from almost no eye fatigue now. If my eyes are tired, it's usually because I'm tired and it's been a long day.

The downside is I now have to juggle two pairs of glasses instead of one, but that's oh so totally been worth it. I'm not going back.

this totally works. I also had a someone add in prism, which really did help fatigue. but for reasons I ended up using the occupational almost all the time, and ended up really screwing with my ability to use perspective to gauge distance. now I'm really poor at judging the sizes of things and I used to be able to tell you at half a meter if it was a 10-32 or a 5mm screw

The brain and visual perception system are incredibly adaptable, even to incorrect prescriptions. Some unwanted adaptions can be reversed by slowly changing any problematic parameters, like (un)training wheels. This would have been inordinately expensive before the era of self-service online glasses.
