Color Blind Glasses CX-013 Color Weak Sunglasses Suitable for Outdoor and indoor color Correction

Bought for colorblind husband. They just made objects and scenery in the house and outside red. Returned

These glasses definitely make a difference. While they give everything an almost pinkish tint I could definitely discern red and greens a bit better than I usually can. They are not something that I am going to wear around all the time but in cases where I think they might be helpful I will. Point in case, there is a particular PowerPoint presentation that used shades of green and red and it was really hard to tell the categories apart without the glasses but when I wore the glasses I definitely could tell the difference and the presentation made better sense.
