Scientists in the UK think they may have found a cheap, low-tech way to help fight age-related loss of vision. In a small clinical trial, people over 40 who were told to stare into a deep red light for three minutes a day had noticeable improvements to their sight. They reported being able to see better in the dark and to better distinguish colors.
The word “scallop” usually evokes a juicy, round adductor muscle—a seafood delicacy. So it isn’t widely known that scallops have up to 200 tiny eyes along the edge of the mantle lining their shells. The complexities of these mollusk eyes are still being unveiled. A new study published in Current Biology reveals that scallop eyes have pupils that dilate and contract in response to light, making them far more dynamic than previously believed. Continue reading What Scallops’ Many Eyes Can Teach Us About the Evolution of Vision
One of the strangest things that can sicken us—a rogue misfolded protein that destroys the brain, known as a prion—is even scarier than we knew. Researchers were able to find the prions responsible for sporadic Creutzfeldt-Jakob disease (sCJD), the most common prion disease in people, seeded everywhere in the eyes of 11 patients affected by it. Continue reading Brain-Destroying Prions Also Spread Through Victims’ Eyes
A 37-year-old woman recently went to her eye doctor complaining of itching and watering eyes. While taking a close look, the doctor saw this freaky sight staring back.
It may sound like something out of “Star Trek”: Doctors have implanted a device in patients that has restored some central vision after advanced eye disease left those individuals with only limited peripheral vision. This is the first time that artificial and natural vision has ever been integrated in humans, the U.K.-based research team said.
Scientists have used stem cells to cure blindness in rabbits—which could be incredible news for visually impaired people.
Vision problems may sometimes be the only symptom a person has of a serious cardiovascular condition, a new case report suggests.
