A product that still looks good after a few months is more impressive than something only good on arrival. Online shops that show detailed measurements and care instructions usually get my attention. For daily use items I try to balance price, build quality and real user feedback. The main things I look at for glasses are frame weight, hinge quality and lens coating. Sometimes I do not mind waiting longer if the price is fair and the quality is solid.
If anyone is interested in real user experiences, I sometimes write short notes about the shops I test.

Loose hinges make the glasses slide down the nose again and again. Everyone has different expectations, but real photos and detailed comments are useful for everyone. I also started paying attention to how websites display sizing charts for clothing. It makes it easier to compare with an old pair of glasses that already fits well. Recently I have been testing several online eyewear shops to compare frames and lenses.
Just sharing my personal feedback.
