They've come out now with glasses for the color blind. I didn't know such glasses existed but they're out there and apparently work. I've been waiting for hunting season to try em out. They come with a 30 day return policy in case they don't work for you. I've never been able to blood trail a deer so I've been pumped up at the prospects of solving that problem. Anyway, I took their online color blindness analysis today and found I have the most severe red green deficiency you can have. Glasses for me will more than likely give only subtle improvement. They said it's 50 50 whether they'll work at all for me. If you're a deer hunter who's color blind you might want to check em out. I've read good reviews by those it helped. Enchroma.com is the one I had settled on, but there are several others. My grandson is 13, color blind, and loves to hunt...I hope these will change it for him. I know there's a lot of color blind hunters who haven't heard of these glasses. I hope this will help you.
