Vision

Most snakes can only see the colors blue and green, along with ultraviolet light in some cases. New research, however, suggests that sea snakes have evolved to actually regain the wider-color vision of their earliest ancestors.

Most of the impacts of a warming planet are fairly obvious. But here's a strange one: researchers have found that older adults living in climates with higher average temperatures suffer a significantly increased rate of serious vision impairments.

Inspired by the human eye, researchers have created a tiny device that captures, recognizes and memorizes images enabling it to make quick, real-time decisions based on what it sees. The device could one day be used in self-driving cars.

It goes without saying that the cameras on self-driving cars can't see around the corners of buildings. The ORCa computer vision system, however, could one day allow them to do so … with a little help from shiny objects that they can see.

A new technique may one day help restore sight to patients with inherited vision impairment. The regenerative therapy works by expressing genes that convert dormant cells into new light-sensing cells in the retina to replace those lost to disease.

Sony has paired with QD Laser to create a retinal projection camera kit. By bypassing the outer layers of the eyes, the kit allows those who would otherwise have difficulty doing so see and capture the world around them.

One of the leading causes of blindness, age-related macular degeneration causes the center of an older person's vision to become blurry or even completely absent. Arges glasses are designed to help, by relocating the unseen images.

Fruit flies differ from us in many ways, including the fact that they can't move their eyes relative to the rest of their head. That's not a problem, however, as new research shows that they move their retinas within their unmoving eyes instead.

Scientists studying the aging process in the eye have made an important discovery around the role of a so-called "youth" protein, and shown how it promotes a healthy recycling process that maintains our vision.

Scientists in Europe have discovered a molecular “zipper” mechanism that can lead to cell death in the genetic disease retinitis pigmentosa. The good news is that injecting certain proteins could slow or prevent vision impairment from the disease.

When you view the image above, does it look like black smear in the center is expanding? If it does, that means you're like most people – and your brain may even think that you're entering a tunnel, adjusting your eyes accordingly.

Cataracts are one of the most common forms of vision impairment, and unfortunately surgery is the only real treatment. But the clouds may be parting on a new drug treatment, improving the vision of the majority of mice it was tested on.
