Can These Glasses Help The Colourblind? We Put EnChroma To The Test

A company called EnChroma has built a pair of glasses that claims to restore colour vision for the colourblind. Predictably, the internet has erupted with excitement. But it’s not the first instance in which a piece of technology has made this bold assertion, and the science behind colour perception isn’t straightforward. We decided it was time to figure out what’s really going on.

A Mad Science Experiment Proves A Simple Evolutionary Hypothesis

You may consider your eyes a priceless commodity, but for Mexican cavefish, they were a burdensome expense. In a first-of-a-kind study, scientists have figured out exactly how much energy an animal saves by abandoning vision — in this case, anywhere from 5 to 15%.

23 Facts About Your Eyes (And What Can Go Wrong With Them)

Our eyes are a fundamental part of the human sensory system — but they’re complex things that can easily go wrong. Here are 23 facts about your windows to the world, including 11 things that can go horribly wrong.

Neuroscientists Are Still Confused About #TheDress

The dress is back — this time with peer-reviewed science. Months after the blue-and-black (OR IS IT white-and-gold?) dress provoked a bajillion arguments, scientists come armed with new studies. But they still can’t solve the fundamental mystery behind the dress.

The Real Science Behind The Crazy Night Vision Eyedrops  

When I called up the Columbia scientist whose mouse experiments inspired two biohackers to squirt chemicals in their eyes to induce “night vision”, I expected, at best, cautious optimism. I did not expect him to tell me that, oh yeah, once, in his younger days, he hooked himself up to an IV and tried it, too.

Simple GIF Vision Test Shows How Good Your Eyesight Is

Do you see Albert Einstein or Marilyn Monroe? If you see Einstein, that means your vision is good! If you see Marilyn Monroe, your eyes need some help. In the GIF above, you should see both as it zooms in. When the image is further away and smaller, you’ll see Marilyn. As it comes closer, you’ll see Einstein. The quicker you see him, the better your eyesight.

This Contact Lens Can Zoom In With A Wink Of The Eye 

This little cone of plastic that fits on your eyeball is actually an extremely thin telescope that can be turned on and off with a simple wink of the eye.

These Helmets Let You See The World As An Animal

These sleek, polished metal helmets may look good from the outside — but from the inside, they reveal the world in a whole different way. You see, they allow you to take in your surroundings as if you were an animal.

Humans Have Been Able To Perceive Infrared Light This Whole Time 

The human eye is a more complex and mysterious thing than we thought. Recently, a group of scientists were puzzled by flashes of green light they saw from an infrared laser, whose light should have been far outside the visible spectrum. Like scientists do, they investigated. Human eyes do indeed perceive infrared light, they found, but not they same way they perceive ordinary colours. It’s weirder than that.

Contact Lenses Used To Be Made Out Of Glass

Did you know that before the age of plastic, contact lenses were made of glass? It’s true! And slightly horrifying!
