People across the globe all see millions of distinct colors. But the terms we use to describe them vary across cultures. New cognitive science research suggests it's about what we want to communicate.
Phosphenes are an experience of seeing light without light entering your eye. Bionic eye recipients use these to map out a visual scene.

We're used to thinking of our eyes detecting light as the foundation of our visual system. But what's going on in other cells throughout the body that can detect light, too?

Cataracts are one of the leading causes of visual impairment globally.

How does your brain deal with the ambiguous and variable visual information your eyes collect? Neuroscientists think it bets on what's the most likely version of reality.

Robots that can learn to 'see' the world around them -- and share their learning with other robots -- will lead the next revolution in robotics.

The pink ball introduced to this year's day night cricket test can be difficult to see for some players, especially if they are colour blind. There is a better choice of colour.
