Reviews

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!"

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."
