Ask HN: Do your eyes bug you even though your prescription is "correct"?

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.

The solution for me to eliminate headaches when working at computer screens was getting an extra set of intermediate distance glasses specifically for computer work. The "computer screen distance" of 3 ft is in between book-reading distance of 1 feet and driving distance 20'+ feet. I also avoid progressive lenses or high-index lenses for computer work. I commented about how arrived at this solution previously: https://news.ycombinator.com/item?id=15375221

Reading glasses work fine when the screen is very close to your face such as a laptop screen. However if it's a separate monitor that's ~30 inches away, reading glasses are slightly blurry which can lead to eyestrain and headaches.

Look into it if you suspect it's a contributor to headaches: https://www.google.com/search?q=computer+glasses+%22intermed...

I have a very weird situation where my right eye was fine but my left, for reasons unknown, has a thicker lens. This can be happen with cataracts but I'm just under 50 and have zero clouding. The eye doctor said it's not myopia in the "usual" sense but the end result is the same: myopia prescription lens.

Thing is, I ignored it for about 10 years and my brain simply ignored whatever signal was coming from that eye. I'd look at things and see no blurring unless I closed my right eye. However, at a certain crossover distance my brain "switches over" because my left eye has amazing close vision and my right eye doesn't. I can actually feel it when this happens, like a physical sensation. No headaches, but it is "odd".

Anyway, I decided to get glasses, and it turns out I need two different prescriptions. One is close up (not longsightedness, it is still a myopia lens). The other is for 1m-∞

A myopic prescription can actually be good for seeing things close up but not in the distance- explains why you’re able to see close up with that eye OK
