Glasses Worry

I had a dream last night that I got my new glasses and they were all messed up. They put the lenses in upside down with the close up bit at the top. They glasses made me look feminine and there was something else too. I don't remember. Can you guess that I'm worried about buying something so personal and long term as a pare of glasses online sight unseen as they say? Well, I am. I just can't afford a pare of glasses bought at my doctor's office. At least this way, I get glasses.
