Of all the readers in my collection, the Jollynova Biron Vintage are my go glasses. After my first pair, I ordered another set along with another (which I'm not as enamoured with - see other review). They look great, but equally important is the lenses quality - no distortion, clear, and comfortable both to wear and for my eyes (no fatigue hours later). In terms of distortion, I can walk around with them without needing to remove them (2.0 optical) unlike most readers. The greatest compliment is that I forget I have them on. I will be ordering a third set soon.
