I've NEVER noticed this; but I did notice that my vision was getting worse over time, I finally went to an optometrist, and yeah, I needed a bit of correction, but I also found out I have an astigmatism. so that's something.

Lights don't look any different than they always have, no blooming or streaks or halos or star lines or anything; but I still have it, and it makes things blurry and it sucks.
