That's not true. My glasses are super light and the thickness is not a concern whatsoever. I can shake my head back and forth with my head down and they don't move at all. And for the past decade since my Rx got particularly bad I have always found the aberrations annoying, so no, I won't "just get used to them".

I can't stand chromatic aberrations because they make everything outside of the centre of the lens blurry. This worsens my tendency for one eye or the other to wander if I'm trying to focus on something just at the edge of reading distance (road signs or restaurant menus, for example) and makes driving at night in the rain difficult. My current glasses have an acceptable amount of abberations, but my previous set was horrible.

I really should be wearing contacts and I've tried them several times, but I generally find them very uncomfortable and I've always hated how they take away my perfect close-up vision.

Yeah, I've stepped down from the highest index I've used due to the aberrations. Material and grinding techniques have improved since then in general, but it was quite distracting - shift my head a degree or two and bam, rainbow, and further to the edges of the lens it'd be 3+ distinct colored images of every light source.

It was kinda neat to be a walking spectroscope, and see what different light sources produced. But the novelty wears off fast when it starts blurring and coloring text on the outer edges of computer monitors. I'm plenty happy paying another $100-200 every few years for lenses that don't do that.

It's strange. I have a high index but ... seeing rainbows? I can't relate to this. Why is that? For me, only blue LED'e shift slightly,

It's worse with stronger prescriptions, if that explains anything. And it has in general gotten a lot better in the past 10-20 years or so, so if you're looking through a current pair it may be quite different.

Currently, if I look at any sharp contrast edge in daylight and turn my head a few degrees, it'll be lightly fringed by either blue or orange. In the dark with a three-color RGB LED projecting "white" (rather than a broad-spectrum white source) I can get fairly clearly separated dots of different colors closer to the edges of my lens.

Have you tried contact lenses? I wouldn't mind, but I can't focus properly and read with contact lenses. With normal glasses that's never an issue.

They consistently glue themselves to my eye if I don't use eye drops literally every single hour. Miss it once and it might take a half hour to loosen and peel them off.

Not really an option unfortunately, my eyes are apparently too dry.

Also - the only aberration I notice is with blue light e.g a bright LED. It goes away if you look directly at it. How is your experience?
