Eye

While scientists have successfully produced various "organ-on-a-chip" models of body parts, the eye is particularly challenging, as a tear film is regularly moved across its surface as we blink. That action has recently been replicated, in a new device.

The CRISPR gene-editing tool has been used inside the human body for the first time. In a new clinical trial, scientists at Oregon Health and Science University are testing the technique as a treatment for a genetic mutation that causes blindness.

It can sometimes be challenging for ophthalmologists, making definitive on-the-spot diagnoses of eye problems. A new "smart" contact lens is designed to help, however, by changing color in response to two common disorders.

Age-related macular degeneration is one of the leading causes of blindness, and there may now be new hope for treating or even preventing it. An international team of scientists has identified a specific protein that may be the cause of the disorder.

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.

Although contact lenses may be less awkward than glasses, they do have their drawbacks – among these is the fact that they can cause "dry eye syndrome." Help could be on the way, however, in the form of a self-moisturizing contact.

Austin-based game developer Frank Force has won the Best Illusion of the Year prize for his mind-bending yet simple animation of twisting rings that seem to be rotating in different directions simultaneously.

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?

Artificial retinas have the potential to restore some sight to people with certain kinds of blindness, but they contain complex electronics that can overheat. Now a Stanford team has found a way to potentially bypass the issue.

The Injectsense implant is designed to constantly monitor a glaucoma patient's intraocular pressure, transmitting readings to the cloud.

A new device has been designed to improve diagnosis of dry eye disease, perhaps also leading to more effective treatments.

An app designed to detect early signs of several eye diseases has surpassed an 80 percent accuracy rate, equaling the sensitivity of devices used by trained ophthalmologists.
