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

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.

There's an interesting new treatment, Miebo in the US, Evotears in other areas. It's basically a tear film reinforcer (pure PFAS!)

It's really eerie how moist it makes your eyes feel after even a few uses. I have definite reservations about instilling megadoses of PFAS directly into my eyes but there's no doubt that it is amazingly effective.
