Buying Eyeglasses Online

Maybe this was a bad idea on my part.  First off, I have a strange prescription with a lot of astygmatism in one eye.  I have worn the same pair of glasses for about 8 years and they are getting old.  I found some nice Ray Ban frames at Lenscrafters that fit my face well.  I researched the price online and the cheapest I could find was through the AAFES for around $200 because of the more expensive lenses.  Then I started to check out other websites because there are many discount eyeglass retailers online.  I would imagine that they are able to keep prices lower because there are not as many options.  There were a bunch of them that do not even allow for large astygmatism corrections.

After searching through a bunch of companies, I opted for Zenni Optical because of the low prices and the ability to change lenses to get what I needed.  I looked at a ton of frames and was tired of looking at them.  I finally narrowed down a few of them and picked one.  Well, being able to personally try on a pair of glasses makes a huge difference.  I received them in the mail today and they are huge on my narrow face.  It's like having skis sticking off the side of my face.  My daughter bumped into them a couple of times, probably because she did not expect them to be there.  I am not sure what to do.  I can return them for a 50% discount or I can use them as a backup to my already backup quality pair.
