Colorblind glasses work by filtering specific wavelengths of light, especially between red and green, to reduce the overlap that confuses the colorblind brain, making colors more distinct and vibrant for them; however, for someone with normal vision, these glasses just add a tint, potentially dimming colors, altering shades (making greens look yellower, reds deeper/browner), and reducing brightness, acting like a colored filter rather than enhancing vision, and can even make night vision worse.
They're usually made for people with certain forms of red-green color blindness (the most common type). Unfortunately, there's no cure for color blindness right now. These special glasses can't give a colorblind person normal color vision, but they could help some colors look more vibrant or noticeable.
