Some people with color blindness are finally getting to see actual colors.
About 300 million people in the world are color blind, and that can affect daily life. Imagine realizing peanut butter isn't actually green.
A type of special glasses let those who have red-green color deficiency see normally.
They also let the user see more vibrant and saturated colors. But they don't work for everyone.
And they're not cheap. A pair for kids will set you back $269, and adult versions can cost as much as $429.
