A Yale-led study uncovered unexpected communication between retinal visual pathways that were thought to operate separately. Researchers at Yale School of Medicine (YSM) have discovered unexpected insights into how the eye handles visual information. When we view a scene, the visual system quickly separates different features, including color, contrast, and motion, and processes them…

A steroid alternative may offer a new way to treat dry eye by restoring the eye’s natural protective defenses. Scientists at Baylor College of Medicine and Okayama University in Japan have developed an experimental eye drop that does more than calm inflammation. In mouse studies, it appeared to restore some of the eye’s own protective [...]

A new study suggests that something as simple as how you position your head during sleep could influence eye health in unexpected ways. Sleeping without a pillow may help reduce elevated pressure inside the eye, according to early findings published in the British Journal of Ophthalmology. High intraocular pressure can damage the optic nerve and [...]

A new study reveals an unexpected mechanism behind how humans develop sharp, color-rich vision before birth, pointing to a coordinated role between key biochemical signals in the retina. Humans begin developing sharp vision before birth through a coordinated interaction between a vitamin A–derived molecule and thyroid hormones in the retina, according to scientists at Johns [...]

Dim indoor light and prolonged close focus may be quietly fueling the global rise in nearsightedness. For many years, the sharp rise in myopia — or nearsightedness — has largely been blamed on growing screen use, especially among children and young adults. However, researchers at the SUNY College of Optometry say the explanation may be [...]

Though we’ve all had to fake a smile at times, it doesn't feel good to receive _or_ give one. Some have gotten so good at offering fake smiles that others may begin to wonder if a person’s smile is _ever_ genuine. To put this worry to bed, a body language expert explains the tell that can separate the genuinely happy from the passively polite.

A snail that regrows its eyes may hold the genetic clues to restoring human sight. Human eyes are intricate organs that cannot regrow once damaged. Surprisingly, they share key structural features with the eyes of a freshwater apple snail, an animal capable of fully regenerating its vision. Alice Accorsi, assistant professor of molecular and cellular [...]
