Zennioptical.com does not sell brand name designer eyeglasses. Zennioptical is a manufacturer and sells only their brand. So that means you are buying direct from the factory and it can mean huge savings.
Here's is how it works. First you need to have your current eye prescription and your PD which is the distance between your pupils from center to center in measured millimeters. Then you choose the type of eye prescription you have, single, bifocal or progressive, and then you select your PD. Once you choose that, a list of frame options that can handle the type of lens you need will pop up.
Next you choose the frames you want. They range in price from $6.95 up to $46. If you need single vision basic lenses, the cost is included in the frames.If you need bifocals or progressive lenses, it will cost you more and that can range anywhere from $24 up to $67.
All the frames you purchase include anti-scratch coating, full UV protection and a case with a cleaning cloth. Basic standard shipping cost is $4.95 per order, not per frame.
Once you choose your frames you can see how they look on your face by uploading a picture and entering your PD number using their Zenni frame photo upload. Click on the "try on" icon for the frames you want to try and it will pop up on the picture of yourself you provided.
Once you find the frames you want, punch in your eye prescription and if you want any other additional features select them and then pay using a credit card or PayPal. Your new eyeglasses should arrive 1 to 2 weeks from when you placed your order. If you happen to make a mistake, you can email them within 24 hours and not be charged, but if it is beyond that time frame you will only get a 50% refund.
I purchased a complete pair of single vision eyeglasses from Zennioptical with the frames and prescription lenses including shipping, my total cost was under $29!
Another company that sells prescription lenses for a bargain is Eyebuydirect.com. Their shipping takes a little longer but in the same price point. Keep in mind both of these companies sell their own frames so no designer brand frames on these sites.
