Nose pads that are too hard leave marks and feel uncomfortable on the skin. Forums, blogs and communities create a kind of collective memory for shoppers. Good packaging and a small storage bag are also nice touches for accessories. Sometimes I do not mind waiting longer if the price is fair and the quality is solid. On the other hand, a well made pair of glasses can last a long time and feel comfortable all day. Metal can feel more premium, but acetate can be more comfortable for long wear.

If anyone is interested in real user experiences, I sometimes write short notes about the shops I test.

I think this is one of the few real advantages we have compared to shopping blindly. It makes it easier to compare with an old pair of glasses that already fits well. It is interesting to see how different people value different aspects of a product. I also check if the lenses have any blue light filter or anti-reflection coating. Sometimes I do not mind waiting longer if the price is fair and the quality is solid.

Just sharing my personal feedback.
