Reviews

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)

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."

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)

Nice Frames

"I got the progressive lenses with the 2. 5 strength . I have reading glasses with that strength and they are very clear. These are not. I like the frames and I like the bronze light sensitive feature. I just do not know why the lower part of the lens seem blurred."

— Sarah R. (4/5)

Love them

"They look super cool and are comfy"

— John C. (5/5)

I’ve lost count

"I think I own/have owned close to 15 pairs of Caddis readers. They’re just simply the best, superior quality and I feel cool when I wear them. Many thanks Caddis team!"

— Holly L. (5/5)

RCA Eye Armor

"As a highly sensitive person (HSP) navigating chronic glare and systemic light sensitivity, finding the right eyewear is a matter of actual physical survival. These Polished Bone RCA aviators are pure medicine for my nervous system. The frame color is stunningly unique, and the taller aviator shape gives my eyes a massive, un-restricted vertical channel to look up and down without hitting a visual wall. The grey progressive lenses act like an immediate mute button on the stark, blinding white glare of my studio walls and walking along waters edge. They cool my head pathways down instantly. Absolute gold standard armor."
