Bifocals have lines and allow for two prescriptions and two distances. Progressive wearers should avoid aviators and cat-eyes because both can cut off the bottom portion of the prescription, resulting in a loss of reading vision.
Instead, they should look for shorter frames with rounded edges such as horn-rimmed, retro wingtip, circular, and oval ones. Premium Progressive Lenses These lenses are computer designed with small changes to allow both eyes to work together.
They often incorporate the fact that you have a dominant eye. As expected, these lenses are more expensive than standard or entry-level progressive lenses. Yes, no-line bifocals are real. However, as bifocals cover two prescriptions, it makes more sense to call progressive lenses no-line multifocals instead of bifocals since they can handle three prescriptions. The Zeiss family usually has very good light transmission and little distortion. And in this respect, Zeiss lenses really show high-end performance.

We at Zenni Optical pride ourselves in the speed with which we deliver to our customers.
Unfortunately, one of our shipments was delayed by Customs due to a bureaucratic oversight. Your order XXXX was part of that shipment. That shipment has now been released and we are working extra hours to get your order to you as soon as possible. We plan to ship all orders within the next 48 hours; you should receive your order a few business days thereafter.
Please expect a subsequent email with your tracking number in the next few days. Sincerely, Zenni Optical Customer Service If I'd remembered just how long that pair took to get here, I wouldn't have bought another pair, but now I'm waiting on the pair that I ordered on Jan. Hopefully, I'll get it without any trouble. Maybe if we send a few emails their way, they'll wake up and figure out that their shipping and customer service needs serious work.
Twelve bucks is a great price to pay for glasses, so I hope they get things straightened out. I'm not going to buy from them again if it takes that long to receive my order this time. Update: just got an email: XXXX, We will ship your glasses from the lab in China on 4th February, and the time when you get it may vary slightly depending on your location.
By the way, your patience will be greatly appreciated. Thank you for selecting Zenni Optical for your vision needs So hopefully I'll get them at, um, some point.
