Color Blind Glasses for Men, Ultra-Clear High-Definition Lenses, Red-Green Color Blindness Vision Correction & Enhancement Eyewear, Full-Frame

I've been religiously wearing them for 90 days like the recommendation said. The change is not subtle anymore. It's profound. My world is permanently richer. I don't just see better with them on; my color memory has improved even when I take them off. Consistency is absolutely key.

These aren't like regular glasses that correct focus. They're a filter that gives your brain the right information to work with. It takes time for your brain to learn what to do with that new data. Once it does, it's incredible. I finally understand what people mean by 'fire engine red'.

Gave these to my brother who's color blind. He was thrilled! Great gift idea for anyone with this condition.
