Plants can tell when competitors are nearby because they can see them.

What color is a banana? Duh, it’s yellow. But what is yellow? Now that you mention it, how do we see color in the first place? That’s the series of questions that led me to making this video. It started simple and took me down a rabbit...

Most of us can only see certain wavelengths of light our entire lives. So why can salmon switch on night vision? We'll learn how they can reshape their eyes to see into the infrared.

We know that not everyone's vision is perfect, which is why some of us need glasses. But some people can also just see more stuff than others! From seeing UV and infrared light, to even having bonus color receptors in our eyes, there are...

Those eerie shining orbs staring at you from the bushes when you take the trash out at night could be any number of animals, but why do their eyes glow like that? Hosted by: Michael Aranda

Cats are known for having fantastic night vision, but why is it during the day my cats can't see the treat that I'm putting right in front of them?

Natural selection can lead to some pretty amazing adaptations, but sometimes the resulting traits aren’t the most efficient solutions to the problems at hand. With the bar set to “good enough,” here are some features that arose from...

The animal kingdom boasts an incredible diversity of eyes. Some rotate independently while others have squiggly-shaped pupils. Some have protective lids, others squirt blood. But which creature has the best sight? Which sees best in the...

This week scientists invented futuristic technologies that sound made up by Hollywood’s spy movies, and we might be able to have infrared supervision without goggles...soon.

The newest 8K TVs have 33 million pixels - but can you even see that many?

As you get older, your eyes worsen and become susceptible to a disease called age-related macular degeneration -- the leading cause of blindness, with no cure in sight. Sharing the science of how your vision works, researcher Joshua...

Some fish have superpowers! Zebrafish eyes can boost the color and contrast of what they see and baby whale fish are electric.

Your eyes don’t always capture the world exactly as a video camera would. But the eyes are remarkably efficient organs, the result of hundreds of millions of years of coevolution with our brains. Michael Mauser outlines the similarities...

We tend to think of blindness as something you're born with, but with certain genetic diseases, it can actually develop when you're a kid, or even when you're an adult. But could blind eyes possibly regenerate? David Davila explains how...

To human eyes, the world at night is a formless canvas of grey. Many nocturnal animals, on the other hand, experience a rich and varied world, bursting with details, shapes, and colors. What is it, then, that separates moths from men?...

Next stop in our tour of your sensory systems? VISION. With a little help from an optical illusion, we take a look inside your eyes to try to figure out how your sense of vision works -- and how it can be...

The process of seeing is a collaboration between the brain and the eye. How does the eye work to create sight, from the lens and iris to the pupil, retina and optic nerve? Biology - Being Human - Learning Points. A far larger part of the...

This video examines the retina's photoreceptors, rods and cones, and their roles in vision, particularly in color perception and low-light conditions. It also explores optical illusions, showing how the brain can be tricked by visual...

Staring at bright lights or the sun will leave a spotty imprint in your field of vision. STAT reporter Megan Thielking explores why.

In this video, we learn about how we perceive colors, including the beloved color pink. While pink is not part of the visible light spectrum, our eyes and brain work together to interpret the color pink from the light bouncing off...

Staring at an image or screen for a long time tires our eyes out and can result in some strange visual affects. Explore the science behind this phenomenon and test your eyes on a few examples.

People across the U.S. will be able to watch Monday's solar eclipse — but can watching it without any eye protection hurt your eyes?
