Today I was contacted via Twitter by Optical123.com who is a manufacture or cheap prescription glasses. Now in the past I have posted about www.eyebuydirect.com and other companies. I still stand by my love of Eyebuydirect.com as the low price leader in online prescription glasses.
The difference that I found with www.optical123.com is that they have a larger selection and style of frames. But they are more pricey. They too have the $7.95 deal on glasses, but are high on other options. They also are based in Hong Kong which means having an extra weight time for your glasses.
All in all I would have to rank Optical 123 as 3 on my list of cheap living.
