9-Level Tint
The Problem
Tired of Sunglasses That Never Fit the Light?
☀️ Too dark for cloudy mornings. Not dark enough for beach days. Most sunglasses have one fixed shade — and it's never exactly right.
✅ ShadeFlex™ gives you 9 adjustable tint levels. Twist the frame. Match the light. One pair for every condition.

Game changer for driving
I drive for work and the light changes constantly. Being able to twist and adjust on the fly is something I never knew I needed. These are now my everyday glasses.

Bought as a gift — they loved it
Got these for my husband who fishes every weekend. He was skeptical but after one trip he said he'd never go back to regular sunglasses. The case is super nice too.

Very unique product
Works exactly as described. The adjustment is smooth and easy. Style is definitely different — I get compliments every time I wear them. Took off one star because shipping took a few extra days, but the product is great.

Finally a pair that works everywhere
I've bought and returned so many sunglasses because they were either too dark or too light. ShadeFlex™ is the only pair I've kept in 3 years. Absolutely love the retro look too.
