ThinOptics with keyring case. Thin, lighter weight, compact, easy folding mechanism to fit case, high quality optics, reasonably comfortable on nose. https://www.thinoptics.com/en-gb/products/readers-black-keychain-case?varia...40664563122210
Nooz rectangular. Fatter, robust looking, but poorer optics than above, not, for my nose, that comfortable for using as creates pressure points and the glasses angle alters easily with general use. https://www.thinoptics.com/en-gb/products/readers-black-keychain-case?varia...40664563122210
Both have survived unscathed for many years, but I find the ThinOptics far better for comfort and quality of optics. Appear fragile though, but mine still perfect after more than 6 or more years (forgotten how long I’ve had them). Mine also fit in a keyring case very easily and so very compact for general carrying.
I originally bought the Nooz for hillwalking etc. thinking they would be better being larger, more robust looking, and therefore not as easy to lose or damage. However, after very little use I decided weren’t that good (comfort, quality of optics) and so bought the ThinOptics. When I buy again, it will be the ThinOptic personally. Of course wind will take both pairs off your nose fairly easily so some care has to be taken.
Just my thoughts - as I said mine are old now, I can’t comment on quality/fit etc for current ones obviously.
