Color blindness-correcting contact lenses

Recommended Posts

Still Waters

Imagine seeing the world in muted shades—gray sky, gray grass. Some people with color blindness see everything this way, though most can't see specific colors. Tinted glasses can help, but they can't be used to correct blurry vision. And dyed contact lenses currently in development for the condition are potentially harmful and unstable.

Now, in ACS Nano, researchers report infusing contact lenses with gold nanoparticles to create a safer way to see colors.
