My glasses started to run closer to a thousand dollars at conventional eye exam offices. I tried Zenni for a backup pair a few years ago, and I was so impressed I am only ordering glasses from Zenni now. They consistently get the prescription spot on, and they arrive usually in around 10 days from China. That's pretty amazing when you think about it. I get 1.67 high index, photochromic with blue light blocker technology included with frames and shipping for around $110. Versus $750 a few years ago. A penny saved is a penny earned!
