If you’ve ever wondered what it might be like to see the world as a lizzard or a bumble bee or some other animal, you’re in luck: a new peice of open access software allows you to see how other creatures see the world.
With more than 150 million people 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…
Absent from the visible spectrum and neither a wave nor a particle, the color pink is, for many, a scientific enigma: how can a shade that doesn't even appear in the rainbow exist? The answer lies in color theory.
Some people can "see" their own hands waving in front of their faces while in total darkness. It shouldn't be possible, but a quirk of their senses allows these people to perceive movement without using their eyes.
These smart glasses could help bring sight to thousands of blind people, by converting visual information into images that can actually be seen by the visually impaired.
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?
Hiding in the shadows between the colors we see everyday are weird, impossible shades, colors that you shouldn't be able to see and generally don't... unless you know how. Here's a simple guide to seeing impossible and imaginary colors.
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…
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…
Google's glasses were a little bit of a let down for those of us who wanted a true head-up display. This video, however, depicts a fictional future where the head-up display powers all our digital lives—and it's equal parts awesome and terrifying.
Every human has limits. You can only run so fast, jump so high, and go for so long without water. But what about restrictions upon our five senses, those tools that we use to perceive and understand our surroundings? Here are ten limitations on human perception that have a direct impact on how we understand the world.
Our eyes are wonderfully complex biological devices, which most of us take for granted. But do you know that our perception of detail varies massively across our field of view? Or understand why we can walk in the dark but not read? This interactive cartoon does a great job of explaining those complex ideas and more,…
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 infrared-slurping photovoltaic pixels—so it can power itself.
Stem cell research, while controversial, has always been touted as the future of disease treatment. There's more evidence to support that claim, as it turns out that stem cell treatment can help cure blindness.
Gymnastics is one of the most physically demanding activities imaginable, and you would assume it's a good idea to have complete use of your eyes while performing aerial somersaults. But science never got anywhere by taking assumptions at face value.
Relative to pretty much any other mammal, humans have an absolutely atrocious sense of smell. But even our weakest sense is powerful enough to affect how we think...starting, of course, with how attractive other people look.
Hiding in the shadows between the colors we see everyday are weird, impossible shades, colors that you shouldn't be able to see and generally don't...unless you know how. Here's a simple guide to seeing impossible and imaginary colors.
Lance Corporal Craig Lundberg lost his sight to a rocket-propelled grenade in 2007. Now, thanks to a fascinating technology, he can read words and make out shapes using his tongue. It's truly incredible.
