When every picture has different colors or extreme filters, it is usually a bad sign. If buyers say the item runs small or large, I always adjust my choice accordingly. Recently I have been testing several online eyewear shops to compare frames and lenses. Personally I like a mix of design, comfort and realistic pricing. I do not trust only the star rating, I like to see detailed photos and longer comments. If they ignore basic questions or reply with copy pasted text, I become suspicious.
If anyone is interested in real user experiences, I sometimes write short notes about the shops I test.

I am still learning and testing different brands and styles over time. For example, I compared cotton, polyester and mixed fabrics for similar clothing items. I think sharing honest feedback helps other buyers avoid the same mistakes. Of course shipping delays can happen, but good communication reduces stress. I also check if the store explains how to measure PD and frame size clearly.
Hope this helps someone.
