Reviews

In Love With Caddis’ Quality!

"This is my second pair of Caddis in two months. I love the quality. The first pair of these RCA had the wrong prescription. Customer service was great to work with and corrected the problem. Mistakes happen, but great companies correct them. I’m a customer for life!"

— Suzann M. (5/5)

OBSESSED

"I have been buying glasses from my optometrist because they said it’s important to get the prescription in the right place and that ordering online is not a good choice. I was unhappy with their selection and expense so I took a chance and I’m SO glad I did!!!"

— Magdalen S. (5/5)

Fits great out of the box

"My third Caddis pair, and as before, the prescription and fit are just right. Though I wish I could have gotten my beloved Mr Cartoon style in blue, this aviator style frame works well too. A more muted blue/green color, but looks good."

— Polly P. (5/5)

Addicted to Caddis

"My second pair of Root analysis and my 10 th or 11th pair purchased. Love the quality the lens clarity and the fit. I’ve been in the optical industry for 30 years and can’t find anything better than a Caddis for an “over the counter “ reader. Well done Caddis in all categories !"

How you look on the outside can match how you feel on the inside

"At a certain age, readers make your life easier. They do. But you don’t necessarily want to look that certain age. Enter Caddis RCA. When the “cool” kids at work compliment my glasses, and I don’t have to take them off to see distance because I got the progressives, I don’t feel my age. So I’m ordering the same style in sunglasses too — because now my outside finally matches how I feel on the inside. Get ready for the compliments."

Great looking sunglasses

"I found myself using these more as sunglasses than as readers but obviously not ideal for diving etc. I lost them already and will order another pair."

— ANTHONY P. (5/5)

Fantastic.

"I like these a lot. Great quality. Nice to wear. Will probably buy another pair in another Color when I can afford to do so."

— Douglas S. (5/5)

Love absolutely everything about this pair of glasses

"The color is spectacular, the shape is cool, but what I appreciate the most is the weight. They are ultra-light. I owned another pair of Caddis and they were heavy and left a mark on my nose bridge. These do not."

— Carla A. (5/5)

Aging Awesome with my RCA

"I am a big fan of the Caddis D-28 frames! But for sunglasses I prefer the RCA frames so I buy the 0 Mag readers and have my optometrist add my progressive prescription. This Donkey color is a cool shade of grey!"

— Ryan F. (5/5)

Obsessed with My Caddis Glasses!

"I absolutely love my new Caddis reader glasses! They fit perfectly, are super comfortable, and the quality is amazing. They make reading so much easier, and I love that they look stylish too. Definitely one of my favorite purchases—I highly recommend them!"

— Janelle B. (5/5)
