I need to get new glasses and my prescription, like

I've used both Zenni and Eyebuydirect. They're excellent. I need a strong prescription and they'd cost me about $400 getting them at a store nearby. At either place I can get them for less than $150. Anyone who needs glasses should check them out.
Zenni was great! I do like them, but as I said, they process in 7-10 days if you do a rush. I highly doubt anyone will need glasses in the same week... but if you break your only pair, you might! 39dollarglasses can do a same week turn around for under $100.
And yes, @Bobotron, do it! Eyeglasses prices are horrible. They are blatantly and shamelessly inflating the price. It's only as bad as mattresses. I get that they want $200-$700 for designer frames. It's a designer product, you're paying for the latest fashion, the style, the name, etc. The cost of lenses, however, is where the problem is. I figured this was due to cheap Chinese knock parts. I know that my Zenni glasses were made in China, and the lenses were plenty cheap, so it made some sense. But this latest time around, I'm getting lenses that are coming from a registered brand name, using some of the latest technology. Plus, this latest pair of glasses is being cut and assembled in New York.
I'd recommend going to get a new prescription at a fairly cheap place. If you are lucky, you can talk to the person who sells eye glasses (not the doctor) and they'll measure your pupillary distance (PD) and give it to you. Sometimes, though, they only take and give you that measurement if you are actually buying things from them. In that case, there are many guides and tools online to help you measure your pupillary distance.
