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."

Best sunglasses for boat days

"I bought my husband a pair of sunglasses readers last year. We made a once in a lifetime trip to Spain and they still have sand in the frames. He loves it, but I thought he could use a fresh pair. These are exceptional, gorgeous color, exquisite fit. We are Caddis-forever-wearers!"

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."
