A study found pupils respond in the same way to the number of objects in one’s field of vision as they do to light. Experiments revealed pupils dilate in response to images with more dots, indicating sensing numbers is an innate perceptual mechanism.

A study is describing a biomarker to identify a person’s risk of developing anorexia nervosa. The research proposes measuring levels of anxiety alongside a type of twitching eye movement can identify those with, and at risk of developing, the disorder.

Researchers have made a striking breakthrough in lab-grown mini organs. Using induced pluriopotent stem cells, the team induced brain organoids to develop rudimentary eye structures that can sense light and send signals to the rest of the brain.

It's easy for us to forget that our computers are equipped with "electronic eyes," potentially watching us at all times. Scientists are now exploring the dynamics of the relationship, with a creepy – but fully functional – human-eye-like webcam.

Eye tracking cameras and AI analysis can reveal your identity, gender, age, ethnicity, weight, personality traits, drug habits, emotions, skills, abilities, fears, interests, and sexual preferences, says a rather dystopian research review.

Glaucoma can cause vision loss that's currently irreversible. But now scientists have found that removing a membrane in the eye could help transplanted cells migrate into the optic nerve and repair the connections, potentially restoring lost vision.

Spanish researchers have created a new potential treatment for age-related macular degeneration, which is currently untreatable – a biohybrid artificial retina, made of silk and loaded with new human cells that can integrate and repair the damage.

New research is building on the suggestion that our ability to effectively hear something is influenced by the position of our eyes. The study found auditory attention seems to be intertwined with visual spatial attention.

California's EyeQue has launched a Kickstarter for a vision test system called the VisionCheck 2 that makes use of a smartphone attachment and an app to provide personalized eye tests in the comfort of a user's home.

Presently, glaucoma is treated via daily-administered eye drops, surgery, or implanted devices – none of which are guaranteed to be successful. In the future, however, it's possible that a twice-yearly injection could do the trick.

Using gene therapy, Harvard scientists have restored vision to mice suffering glaucoma by rewinding the aging process in their cells. The team says the research is a proof of concept for slowing the symptoms of aging with epigenetics.

A new gene therapy treatment may be able to save the vision of patients with a blindness-causing genetic disease. DOA currently has no preventative or cure, but in tests in mice and human cells the team was able to slow progression of the disease.
