Yes, absolutely. All depends on your prescription and sizes though.
Most decent optical labs operate on a sliding scale, going thinner and thinner, but costing more and more. Can get quite expensive (relatively), but if you're going to absolutely baby your glasses, and use something like Zeiss single-use lens wipes, yes I think it's absolutely justifiable for something you're going to use all day, every day for several years.
About 12 years ago, I switched to rimless with carbon fibre arms to try and get the weight down as the option to go as thin as I'd like just wasn't there yet, and I was still stuck with traditional glass, so the weight was a concern for me, and my glasses were forever slipping down my nose (ugh).
Maybe 4 years ago I switched over to hingeless titanium frames (almost wire-thin) with rimless lenses that are incredibly thin and light, and made out of polycarb. Not got my prescription info to hand, but it's a world of difference what's available now versus a decade ago.
They're so thin and light now that I frequently forget that I'm wearing them, and can even fall asleep in them! Oops! They stay stuck on my nose too, I never need to push my glasses up my nose.
I thought pursuing thinner and lighter would be an exercise in vanity, but I can honestly say it's significantly improved my quality of life.
Mine vary from "too thick for almost any frames" to "looks like a normal pair of glasses until you look through them" depending on cost. Mine are somewhere around 1/3rd as thick on the edge as cheaper glass.
Look for "high (refractive) index" lenses. It bends light further, so you need less material / less angular difference to get the same effect.
Interesting, thanks! I figured the thickness was just a function of physics and couldn't be changed, but I wasn't aware of the difference in refractive index.
It generally comes with more chromatic aberrations (rainbow splitting of high contrast edges / light sources), but the tech keeps improving and my current pair is only barely noticeable in my normal vision window. At the edge it basically makes text unreadable though, just because the aberrations overlap enough.
Which is much much better than like 15+ years ago, when I had a pair that had enough aberration that I was happy to get the thicker ones the next time. It was kinda fun being a walking spectroscope, but definitely uncomfortable in quite a few cases.
There is high index polycarbonate and high index trivex. But polycarbonate has a side effect of the optics getting blurry the closer to the edge of the lens you get.
