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.

Since it hasn't been mentioned yet, I must add this: when we work and focus, especially when using digital screens, we tend to blink a lot less frequently. If tear composition is not good or there are other exacerbating factors (e.g. an AC with high flow), the break-up of the tear film can easily lead to eyestrain and even blurry vision. In such situations, preservative-free artificial tear drops 3-5x a day can lead to pretty good results. In some cases, one needs to try a few, each for a week or two, before finding the correct one. Pro tip: any eye drop can cause discomfort for a few seconds, especially if the dry eye symptoms have persisted for a long time.

I asked by eye doctor why there was so much mucus around my eyes and after she dumped in a little dye she noted my eyes were almost like sandpaper from not blinking enough.

This seems like something that could have a technical solution beyond just putting liquid in your eyes. I am wary as liquids are sometimes contaminated with bacteria or other substances. Perhaps screens or headbands that trigger blink reactions.
