Vision

Impressive new work has demonstrated a potential way to restore vision in those suffering from degenerative diseases of the retina. A single injection of nanoparticles was found to create a working artificial retina, restoring vision to blind rats.

Studies have seen physical activity slow age-related vision loss, but it hasn’t been clear how causal that relationship has been. New research is now offering the first evidence to show how exercise can directly slow, or prevent, macular degeneration.

Scientists at Columbia University have developed a potential new treatment for a major source of blindness in the form of eye drops that preserve retinal function, with tests on human subjects now in the works.

A new study has demonstrated how a form of deep red light therapy can help address age-related decline in vision. Hitting the retina with just the right wavelength of light was found to recharge its energy system in those over 40 years old.

An international team of scientists has developed technology that could detect diabetes-induced blindness in its early stages, using a smartphone as the basis for a low-cost diagnostic method that could greatly improve care in developing regions.

One would think that having normal 20/20 vision is due mainly to the anatomical characteristics of the eye. According to a new study, however, tiny eye movements play a large role – and the findings could lead to new treatments for poor sight.

In the age of wearable computers, scientists in the laboratories of DARPA, Google, and universities around the world see contact lenses not as tools to improve our vision, but as opportunities to augment the human experience. But how? And why?

If you're performing tasks such as design work, it's important that you be able to see the difference in textures of materials. Boasting what its makers call human-eye resolution, the Varjo VR-2 headset is designed with such applications in mind.

Presbyopia is a common form of age-induced far-sightedness. Now a Stanford team has developed a pair of high-tech specs called autofocals, which use fluid-filled lenses, depth-sensing cameras and eye-tracking technology to make sure whatever a wearer is looking at stays sharp.

​Caused by autoimmune diseases, chemical burns, or sometimes even as a side effect of eye surgery, corneal melting is an incurable disease that's a major cause of blindness. It could someday be treated using a contact lens, however, which is currently in the works.

​Have you ever wondered what the world looks like to birds? Well, Swedish scientists have created a camera that will show you. Amongst other things, it has revealed that birds see tree foliage as much more than just a uniform "wall of green."

Researchers at Caltech have revealed two illusions illustrating how our brain can be tricked into seeing something that isn’t really there. The phenomenon is known as postdiction, and highlights how our perception of reality is actually constructed by our brain retroactively.
