Sea urchins do not have eyes, yet appear to be able to see where they are going. One posible answer: they may use the entire surface of their bodies as a compound eye.

How do things look to colorblind people? Colour Lovers (Prev: 1, 2, 3, 4, 5 - all more useful to those who aren't colorblind) offers some popular websites and iconic art, As Seen By The Color Blind. Luckily humans are smart and have created technology like the Color Blind Web Page Filter. Prev. Wiki.

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?

Laser-o-vision: A system that projects light beams directly into the eye could change the way we see the world.

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.

The gift of sight is easy to take for granted. Not for Mike May, blinded in infancy, Mike had partial vision restored at the age of 43. This is his journal, written with infectious delight for his new gift and documenting the unexpected problems that the miracle brings. There's much, much more to vision than just the data and Mike is an unprecedented opportunity to better understand how perception works. [via the Guardian and previously mentioned here]

Re-Shape Your Eyes While You Sleep? Wow - I don't know about you, but if I could wear contacts during my sleep that I *took out* when I woke up and didn't have to wear any all day, and I could see, then I'd do it in a second. When will it become reasonably priced?

Cool eyeball science Quick summary of interesting research on the output of the eyeball. 3 really cool things: 1, we know much more about the output of the eyeball now than a few years ago; 2, they've got a neural network doing visual processing like the eye; 3, most of what you see your brain makes up!
