Reviews

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."

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!"

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!"

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."

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."

The Journey is the Reward

"Do you know how cool you have to be to wear these frames? That’s what I was telling myself every time I tried them on. I finally excepted that I am that cool. I love the frame shape and color and how it balances my face. I’m really happy with Caddis eye appliances, I was going to get LASIK before I found your frames."

Root Cause

"I love these and I love the style even more. I really wish the readers/bifocal portion encompass a little bit more than just a sliver of the bottom portion of the glasses. I have to really tilt my head back to benefit. truly, the best part about them is that I can wear them all day without taking them on and off, even though I have to really tilt back to get the effect of the reader."

Carey A. (5/5)

Did them as progressive
