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!"

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."
