If you don't need astigmatism correction, spherical contact lenses give much better image quality than glasses. You don't get the image minification/magnification that you get with glasses, and the off-axis optical aberrations are much reduced because the lens moves with your eyeball, meaning it's always correctly aligned. Astigmatism correction in contact lenses sacrifices some image quality (sharpness is reduced), but it might still be better than glasses depending on how much correction is needed. It's possible to combine spherical contact lenses with cylindrical glasses, which might give the best overall image quality depending on the exact correction needed. Related to this, different glasses lens materials cause different levels of chromatic aberration, measured by Abbe number. The cheapest (PADC, e.g. CR-39) is one of the best you can get.

This is interesting as I have been a photographer for decades as well as playing various sports, and have had endless fantastic discussions with my opt over the years about the various merits of different lenses and glasses but this has never come up. I wore only contacts from December 1992 to maybe a few years ago, when presbyopia made things impossible, and I have been lamenting - truly lamenting - the state of things with glasses. I procured some Natural Vue lenses for multifocal vision last month, as I had previously tried them with decent results, but the outcome is not good at all. My near vision is rubbish. I wish I could wear contacts again, my QoL has taken such a massive hit. I’m -10 in specs with astigmatism.

  Have you tried monovision contacts? It's not for everyone, but works really well for a lot of people. We've also now got two FDA-approved medicines for presbyopia, with at least two more pending applications. https://www.vuity.com/ https://www.vuity.com/ https://www.orasis-pharma.com/ https://www.orasis-pharma.com/ https://ir.lenz-tx.com/news-events/press-releases/detail/18/lenz-therapeutics-announces-submission-of-new-drug-application-to-u-s-food-and-drug-administration-for-lnz100-for-the-treatment-of-presbyopia https://ir.lenz-tx.com/news-events/press-releases/detail/18/... https://www.ocuphire.com/product-pipeline/phentolamine https://www.ocuphire.com/product-pipeline/phentolamine
