It makes it easier to compare with an old pair of glasses that already fits well. I am still learning and testing different brands and styles over time. Comfort around the heel and toes is more important than super fancy design. I like when a shop clearly shows PD, lens height and bridge width in millimeters. It is interesting to see how different people value different aspects of a product.
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. It is interesting to see how different people value different aspects of a product. I recently tried a few different online shops and wanted to share my experience. Sometimes customer service can fix a bad experience, but not always. I also check if the lenses have any blue light filter or anti-reflection coating. Some charts are very generic and do not match real measurements at all.
Just sharing my personal feedback.
