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.

If you're over 40 and have been wearing glasses for years, you might now need a pair with a weaker prescription just for computer use.

What's the reasoning behind being over 40? I recently complained to my optometrist that I was having a harder time seeing things up close and he prescribed me weaker lenses for work/reading. My regular prescription is right around -7 in both eyes. I'm not over 40.

Presbyopia - the lens in our eyes begin to harden at age 40, making it harder for our eye muscles to "squeeze" the lens to focus. Presents itself as blurriness and eye strain. We usually encounter a change in our Rx during this time too, sometimes needing a weaker Rx (counterintuitively).

Would love to chat about your experience in any case. I'm at jbornhorst [at] gmail.com if interested.

Most people get this after 40. Some people get it earlier.

Presbyopia: https://www.mayoclinic.org/diseases-conditions/presbyopia/sy...

  Presbyopia usually becomes noticeable in your early to mid-40s and continues to worsen until around age 65.
If you're much younger than 40, maybe google "early onset presbyopia".
