The Images in This Video Can Screw Up Your Brain and Vision

I squinted my eyes and covered the screen watching this video by Tom Scott because I don't want to have coloured vertical and horizontal lines ingrained in my vision. So I suggest you do the same and look away. No, seriously. Don't look too long or you're going to start seeing stuff that's not actually there. Read More >>

How the 20/20 Vision Scale Works

With more than 150 million people over in the United States (nearly half of the population) requiring some form of corrective eyewear to compensate for visual impairment, chances are you have had your eyesight graded on the 20/20 scale before. If you haven't, you have probably heard other people saying they have "20/20 vision" or even the phrase "hindsight is 20/20." The vision scale is so prevalent in American culture that there's even a TV news show named after it. Read More >>

If the Colour Pink Doesn't Scientifically Exist, Why Can We See It?

Absent from the visible spectrum and neither a wave nor a particle, the colour pink is, for many, a scientific enigma: how can a shade that doesn't even appear in the rainbow exist? The answer lies in colour theory. Read More >>

Why Your Dumb Eyeballs Keep Falling for Optical Illusions

Optical illusions are fun because you literally can't believe your eyes. But isn't it a little troubling that your eyes can get fooled like that? Why don't they show you the visual truth? How can you ever trust them if they don't? Read More >>

The Artificial Insect Eye That Will Give Sight To Tiny Drones

Humans see the world through a pair of high resolution, single lens eyes that allow us to adjust focus and pinpoint fine details. But simpler creatures, like insects, instead rely on compound eyes that have lower resolution but offer a much wider distortion-free field-of-view that's actually better suited for lightning fast motion perception. And as researchers work towards designing autonomous drones that will behave like futuristic artificial bugs, it's only fitting that they also work to replicate how an insect sees.
Of course understanding and recreating Mother Nature has always been one of our biggest challenges, but a research project known as the Curvace believes it's created a prototype artificial compound eye that comes pretty damn close to the real thing. Composed of three separate layers including an array of microlenses sitting atop an array of photodetectors, the Curvace promises to provide drones with an incredibly wide field of vision that will allow the craft to navigate obstacles even in the dark of night.

Researchers Will Restore Damaged Depth Perception with Electronic Eyes

Our depth perception doesn't work without two eyes. However an estimated 285 million people worldwide suffer from some form of visual impairment in at least one theirs. The loss of sight in just one eye also means the loss of one's ability to accurately judge short distances. However, a team of researchers have devised an ingenious solution to restore binocular vision. Read More >>

The Solar Power Eye Implant Which Restores Sight

Electronic implants which restore sight to the blind aren't anything new, but one of their major stumbling blocks has been the need for an external power source. Now, that's about to change, because a team of researchers has built a digital implant out of infra-red-slurping photovoltaic pixels—so it can power itself. Read More >>
