Sometimes I experiment with different materials just to see how they feel in daily life. Nose pads that are too hard leave marks and feel uncomfortable on the skin. Price is important to me, but quality and comfort are even more important in the long run. I recently tried a few different online shops and wanted to share my experience.
If anyone is interested in real user experiences, I sometimes write short notes about the shops I test.

Reading comments with real body photos is one of the best ways to check sizing. Sometimes a store looks great in ads but the real product is completely different. Sharing real world usage stories is often more helpful than any advertisement. Some charts are very generic and do not match real measurements at all. It makes it easier to compare with an old pair of glasses that already fits well.
