DJI Phantom 2 Vision+ Review: Buttery Smooth Quadcopter Video

DJI has been making remote-control quadcopters for years. Originally, you had to strap your GoPro to it, but last year DJI introduced the Phantom 2 Vision, which had its own integrated camera system. It was pretty sweet, but every tiny turn you took your video shook enough to scramble your viewer's brain. » 4/06/14 8:00pm 4/06/14 8:00pm

Looking at Orange Light Is Like Drinking a Cup of Coffee

Light is an incredibly powerful force. Sure, it helps us see and gives us fast internet, but medical researchers keep stumbling upon new positive side-effects.

The images in this video can actually screw up your brain and vision

I squinted my eyes and covered the screen and looked away when I was watching this video by Tom Scott because I don't want to have colored vertical and horizontal lines ingrained in my vision because my brain got fried from staring too long at the images in the video. So I suggest you do the same and look away. No,… » 1/27/14 11:23pm 1/27/14 11:23pm

How the 20/20 Vision Scale Works

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… » 12/31/13 6:00am 12/31/13 6:00am

This Ultrafast Camera Is Designed to Work Like a Human Retina

Photos and videos are not lightweight files—they quickly add up to gigabytes of data which can be a dealbreaker a lot of research. Engineers at the Swiss company iniLabs created a better way—a camera that borrows its mechanics from the marvels of the human retina. » 8/23/13 2:40pm 8/23/13 2:40pm

Watch How Silly People's Reaction Times Are in Slow Motion

This is fantastic. Distort measured people's reaction time by making them catch a falling ruler to see how quickly (or slowly) their brains can translate what they see into what they do. Putting the video to slow motion emphasizes how silly our reaction times can be. Some of us are so slow we might not even catch the… » 7/05/13 9:00pm 7/05/13 9:00pm

This New Contact Lens Basically Turns Your Eye Into a Telescope

Contact lenses are great if your only issue is near or farsightedness, but for those struggling with age-related macular degeneration (AMD), a leading cause of blindness among older adults, those flimsy little lenses ain't going to cut it—or at least not the kind of contact lenses you're used to. But soon,… » 6/27/13 1:11pm 6/27/13 1:11pm

Of Course This Optometrist's Business Card Doubles As an Eye Test

Here's a brilliant way to drum up new business if you're an optometrist. Myung Dong, an eye doctor in Jeju, South Korea, found the perfect way to convince the local elderly population that they could benefit from glasses or other vision treatments: a business card featuring a self-administered eye test. » 6/20/13 9:13am 6/20/13 9:13am

What Color Means to Blind People

Tommy Edison, the wonderful blind film critic who once showed us how he used an iPhone, has a new video describing something nearly impossible for blind people to understand: color. What's great is that even though Edison doesn't understand the concept of color, colors still have meaning to him. Watch him describe… » 12/06/12 10:00pm 12/06/12 10:00pm

Eagle-Eyed Argus II: An Artificial Retina That Reads For the Blind

The advent of cochlear implants in the 1970s and ocular implants in the early 2000s revolutionized hearing and vision loss treatment by circumventing damaged organs with digital prostheses that directly stimulated neural pathways. But these devices have been poor substitutes for the real thing. That is, until now. » 11/27/12 11:40am 11/27/12 11:40am

The Science of Sight, in Interactive Cartoon Form

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,… » 7/11/12 4:21am 7/11/12 4:21am
