I was wondering about this and asked someone born with 20/20 vision before and they claimed no halos. Would be interesting to hear more opinions on this.

So people born with "perfect" vision. If you stand outside on a dark night and stare at a street light, is the separation between darkness and the light completely crisp, or is there a halo or a starburst of some sort?

I had Lasek done about 5 years ago. The first days after surgery my vision was 100% perfect and light sources were completely crisp and well defined.

However, as my eyes healed, vision degraded a bit and the halo and starburst distortions came back. Nine months later I got a free followup surgery, but that didn't improve matters any.

It's still improved my life a lot, but it sucks going back to distorted vision after seeing perfectly. Also, Lasek sucks. Lasik wasn't an option for me but reading about procedures now I think PRK would have been a better choice (or some laser-only surgery, but I wasn't given that option either), and I certainly wouldn't have gone through a second surgery if I knew it wouldn't help.

I have (as far as I know) perfect eyes. Around bright objects there is a slight halo, best compared to the one you see in video games around streetlights at night. It's much smoother than the one in the illustration in the article and slightly less bright. Bright stars show as dots with tiny lines coming from it with different lengths. Really tiny but still visible. Less bright stars show as infinitely small dots.

OK, so I guess this is just normal and somehow wearing glasses actually changes your vision by removing those artifacts.

Ask a doctor about that. Preferably, not the one who performed the surgery.

As far as I know, there are no halos if you really have perfect vision. Cataracts and minor vision problems (such as a small amount of astimatism) will cause halos, even if the subject claims to see fine otherwise.

If you are doing such a poll, it would be helpful to ask, along with the presence of halos, when it was their last visit to an optometrist. If you believe you have perfect vision, you are not going to see one (even though periodic visits to an eye doctor are indicated, for checkups).

Exactly, I can't remember the last time I've seen an optometrist, horrible things could be wrong with my eyes.

Same here, perfect vision, but can see halo, especially around blue light sources.

Not to be that guy but it could be related to previous psychedelic use in my case.
