Zenni Optical gets lotsa love from online shoppers looking for inexpensive frames, plenty of lens options, and reliable optical quality. I'm a fan because I've ordered from Zenni four times and always been satisfied with the result. The lenses have always been perfect from a prescription/PD standpoint, and the prices are great if you have a rapidly changing prescription or a less-than conscientious spectacle wearer (e.g., a child) for whom you are buying.
Here's what you need to know:
1. Take special care when choosing your frames so that you'll be pleased with what you get. Returning items isn't really a cost-effective option, and Zenni does not offer full refunds. Double check your measurements, use the virtual try-on feature for more success, and remember that you sometimes get what you pay for where the frames are concerned.
2. It takes two weeks to get your glasses (in the USA). Don't expect them much sooner than that.
3. Zenni doesn't often have big, blowout sales, but if you sign up for the emails or "like" them on Facebook, you will occasionally receive notifications about free shipping or other discounts.
4. Don't rely entirely on the search options to find what you want. Zenni has a massive number of frames, and they aren't always categorized the way you think. I have found some real gems (which did not show up when I filtered my search options) by taking the time to go through ALL of the frames. (Yes, it was a bit tedious because the selection is freakishly large.)
5. Use the "add to favorites" option to keep track of your picks, otherwise you may never be able to find them again.
