My daughter is away at Art School with too many projects to write a review, so I'll share her reaction. We took her outside with the Enchroma glasses and her own sketchbook. When she opened the book she started crying. She had never seen her own art the way it looks to everyone else. She was amazed to see the watercolors she thought were shades of brown were actually shades of green and red. The biggest revelation was to see all those blues were shades of purple. Purples are now her favorite colors.

I had never been able to explain to people exactly how I saw colors before purchasing Enchroma's. I just knew I had trouble with Reds and Greens. Now that I can see true, bright, vivid colors it's like seeing in Hi-Def. You see, my eyes are oversensitive to Green which means I have trouble seeing Red hues. Imagine not being able to see a Red bloom on a Camelia shrub because it blends in with the foliage. I mean I know the bloom is Red and I know the leaves are Green. So, what's the deal? But, man, with the Enchroma's the blooms "burst" with color with lots of "contrast" between the foliage and blooms. And purple? Yeah, more like PURPLE ON STEROIDS! Shades I had seen as Green before are actually Blue and what I always perceived as "faded" or "washed out" Pink is actually a deeper, richer, more vibrant color. I'm having to re-evaluate common descriptions of colors because my perception has changed so drastically. It's been pretty wild and I've only had them for a few days now here in February. I can't wait for Spring, Fall, or seeing a rainbow for the first time with correct color vision. Enchroma works for me and I would highly recommend them to anyone who is thinking about investing in them. So, if you're on the edge, don't hesitate. It's worth it.
