About 8% of the male population has some sort of color vision deficiency. The color blind are unable to clearly distinguish different colors of the spectrum, they tend to see colors in a limited range of hues. Because of this, the color blind have trouble with a lot of websites. The patterns and examples on We Are Color Blind help developers create websites the color deficient can use with minimal problems. Take a color vision test to see where you stand. 50 facts about color blindness.

Wearers of Adaptive Eyewear can make their own prescriptions. The lenses are plastic bladders that change shape and corrective power with a small syringe. So far 30,000 people who may never be reached by an optician or afford conventional eyeglasses now have corrected vision. Recipients are now able to read, mend fishing nets, sew, and perform other tasks requiring good eyesight. The inventor, Oxford University professor Josh Silver, hopes his nonprofit organization can begin manufacturing and distributing up to 100 million pairs a year.

"Over and over he scoops up a chick with his left hand, expels its droppings with a squeeze of his thumb, opens its vent with his fingers, peers through the magnifying lenses attached to his spectacles and determines its sex." It's a dirty job (YT). Sexing chicks early is important so that the cockerels can be separated and culled^ or fed to be broilers^. The obvious differences take weeks to develop, so when the vent sexing method was developed in Japan in the 1920s, professional chicken sexers became sought after. [more inside]

Doctors in London have made the world's first attempt to treat a retinal degeneration disorder using gene therapy. "The researchers aim to restore the activity in these cells and therefore restore vision by implanting healthy copies of the key gene into the RPE at the back of the eye. In other optical news, wired.com is leading with a piece about "Luke 's Binoculars" (yes, as in Skywalker) - a gadget that is meant to provide soldiers with a 120-degree field of view and allow him/her to be able to spot moving vehicles as far as 10 kilometers away by integrating EEG electrodes that monitor the wearer's neural signals. CTTWS, I presume?

Hacking the Senses: The brain is far more plastic than we commonly realize. Presenting new 'senses' via the old inputs works extremely well, to the point that long-term volunteers are a little lost without their new abilities to feel magnetic north or absolute orientation. Tasting direction; feeling pictures. Fascinating stuff. In a loosely related article, genetically modified mice are able to see the full color range visible to humans, even though the last natural mouse able to see this way died out a hundred million years ago. Add the new sensors, and the brain reconfigures. [via]

We’ve detected background radiation from the Big Bang. We’ve sent explorers to the bottom of the ocean and the moon above us. We have images of the individual atoms of which our world is made. But we cannot have direct access to the sensory experiences of another human being. Language can help to bridge the gap but it is an imperfect tool. The closest we have come is Brain Fingerprinting and even that only indicates recognition of a scene or object; it does not capture the actual visual memory of the scene or object. This may soon change. Several years ago, researchers at Berkeley wired a cat’s neurons to a computer and were able to obtain videos of what the cat was seeing.

'Twas blind, but now I see? — Virgil surgically regained his sight after nearly 50 years of blindness: "On the day he returned home after the bandages were removed, his house and its contents were unintelligible to him, and he had to be led up the garden path, led through the house, led into each room, and introduced to each chair." In the end, he and others like him [PDF] would have rather stayed in the Country of the Blind. (A happier ending was the more recent case of Mike Mays, previously posted here.)

The Origin of Art in Entoptic Phenomena Relatively recent research suggests cave art is neither simply 'art for art's sake' nor 'hunting magic', rather a representation of entoptic phenomena associated with hallucinations during altered or trance states of consciousness. These images are common to modern and prehistoric humans all over the world, and can be readily found in contemporary art. (see also some further reading, cool entoptic Kutie Catcher, AskMe)

Check out the interactive demos, test your perceptual abilities, and read the research explaining why this happens. Number 12: Color Contrast Cube is particularly startling. Warning: Totally Flash interface, but appropriate for subject matter. More experiments at a less Flash-y associate's site.

The McCollough effect is a visual illusion somewhat similar to regular color aftereffects, but the working mechanism is different, and despite a wealth of theories, not entirely explained. Once the effect is established, it does not seem to go away and can last for days or even weeks. Proceed at your own risk.

Seeing with sound.
A researcher in the Netherlands has developed a system that converts pictures from a head-mounted camera into highly complex soundscapes, which are then piped to the user via headphones. After only a week of use, a woman who has been blind from birth can tell a CD from a floppy, and discern whether the lights are on or off. Not quite up to either a bat and/or Daredevil standards, but very cool nonetheless.

"Rad, wicked, bad, barry, and definitely not sad". Amazingly, James Runcie is talking about glasses. He also describes his own endearing misadventures with NHS specs and how he's changed his opinion from glasses as stigmata (used by "the shy, the gangly, the awkward; people whose voices had not yet broken; the pyromaniacs, the mummy missers, and worst of all, the people who actually liked classical music") to the joy of myopia ("we look in a concentrated manner or not at all, for we cannot bear very much reality"). As to Dorothy Parker's famous dictum, the obsessive, often unsafe for work BBS and links on eyescene should offer some evidence to the contrary.

The doctor will not see you now. Jane Poulson developed Type I diabetes at 13.

Sightless dining. The world of the sightless is a world I don't often explore. In high school, I had two classmates who were brothers and both sightless. I was amazed at the "tricks" they used to cope in day-to-day tasks we take for granted. Dining at Blindekuh (Swiss German for blind man's bluff), where you eat in complete darkness, would be quite an 'eye-popping' experience. There's a four month waiting list for a table.

The BBC, working with the Royal National Institute for the Blind, has created a perl script that reparses a page, stripping out the text from tables and reorganizing it on the fly. It creates a pretty good visually impaired-friendly version of your pages instantly. I don't know how well it does on complex page layouts, but compare the BBC News site in its typical state to the parsed 'text-only' version, and you can see they are pretty close in terms of content.
