I lost my glasses recently and need a low cost options to replace them. My sister told me about a website called zennioptical.com. She said that Zenni: the #1 online eyeglasses store is the only place she gets glasses for her family. I can see why Opticians keep you away from ZenniOpt. because their prices are lower than anyone else I have even seen. Opticians don’t want to give you PD data to prevent you from saving a lot of money by ordering your glasses from Zenni.
