Yet another vote for Zenni. DH just received 2 pair from them, cost around $100 total. He gets the no line bifocals and lens tinting. Plus he has astigmatism which always makes his glasses more expensive. It can take a while to receive them though(and they don't offer express shipping)....2-3 weeks for us. But, I read somewhere on their website that it usually takes longer to receive the no line bifocals. I'm saving 75% on glasses so I think I can handle the wait.
BTW, when you get your prescription from your optometrist, make sure they measure your pupillary distance(PD). Zenni requires this when you order. You can also measure yourself or just go to a
Walmart eye center. Their opticians did it for us even after we told them we needed it to order glasses online.
