I purchased a pair of glasses from ZenniOptical and I am very dissatisfied. Believe me there is a reason that in their term of use they say We urge you to KEEP YOUR CURRENT glasses as a backup pair. The reason is that shortly after the 30 day so called warranty they are going to break. I bought a pair of glasses from them and after 60 days of use, they broke. The actual lens broke where it was attached to the nose piece. Another quote in their terms of use is Zenni Optical is not responsible for lost, missing or en-route damaged goods. So if they get broken en-route you have wasted your money. Another quote is Zenni Optical does not provide repair, replacement or exchange service of any kind. So in other words once you order the glasses and they have the money you are SOL. I thought this would be great due to the high cost of eyeglasses. I paid $100.00 and thought it was great, but it's not so great if I have to pay $100.00 every two months. Please be very leery of ordering your glasses from ZenniOptical. My glasses broke and I can not see to drive or read or use the computer at work without glasses so it is a very very big inconvenience for me because I can not step out and get a pair made same day so I will have to go without glasses for about a week. No more ZenniOptical for me.
