Reviews

Wow. Wow. Wow.

"I really love these glasses. They feel solid and well-made, not flimsy like some frames I've had before. The quality is great, and they seem like they'll hold up for a long time. They also have a unique style that stands out without being over the top. I've gotten a few compliments on them already. Most importantly, they make me feel confident when I wear them—I feel handsome, cool, and like they fit my personality perfectly. Definitely one of my favorite pairs of glasses I've owned."

Surprising Comfort

"I mean my eyewear comfort-o-meter did a double take. . . and the RCA is rad af! My 5th Caddis style and a new favorite. Thanks Caddis."

Michael K. (5/5)

Love these!!!

"I wasn’t sure how these would look but I decided I loved the color and they look so good on most other people - plus the message on them is also cool… Turns out they are very cool! Comfortable… and the best ones I own- as are all of my other CADDIS readers. Unfortunately my husband always steals mine!!"

RCA

"The glasses are amazing. Solid good quality and I love the style. And your service is fantastic! When my initial order got stuck in customs in Italy you immediately sent out another order for me to an address in the US. I truly appreciate it!"

Customer service

"I love my product. It’s great quality and exactly what I wanted. What set this purchase apart from all others was the high-quality customer service! I had an order issue that was resolved extremely fast and professional. They made sure I got my answers to my questions and the product I was looking for. I would recommend for anyone looking for a great product and service that backs it up."

First Time Buyer

"I love my new readers. They have a sturdy frame and the style is great too"

So huge

"I really liked the design of these glasses. They have a great heft to them and seem really well made. I felt like a child wearing an adult's glasses, however, and so they went back for an exchange. I 100% need the smaller, narrow frame."

Tamar O. (4/5)

Good

"Nice glasses but there are some dots and dashes in white on the top edge of the frames. It’s a bit weird because I don’t know why they are there. They don’t add to the glasses. I’d prefer they weren’t there."

Q&A

How do I know what magnification I need ???
You would need to try them on a a local retail store, or contact your vision provider to inquire what strength you would need. You could also order 3 pairs for a 7 day trial with our TryNow feature.
How do I know what measurements to order? I do know the mag., 2.00 I am on the computer for long periods and my eyes burn, so I want to try yours for the blue light blocking.
Hi Tom, thank you for your interest! The blue light protection can give you some relieve. If you are still able to see with the +2.0 I would say order them in a +2.00. Try them on and if you feel like you need more magnification we can exchange them. We offer free exchanges in the US.
