A Different Vision: How can you tell a great white shark is about to attack? It’s their eyes, experts say
Great white sharks have a creepy way of warning they’re about to attack — but it may come a little too late for anything, or anyone, close enough to see it. “They have the ability to roll their eye back when they encounter prey, to protect their eyes,” Mikki McComb-Kobza, of the Ocean First Institute, reported…
Read MoreDo Eye Exercises Improve Your Vision?
Can you really improve your vision with eye exercises? Eye muscles exercises have the potential to improve vision and delay the need for glasses, LASIK or contacts in some people. However, certain underlying conditions that affect vision cannot be fixed with eye exercise, including cataracts, farsightedness, myopia (nearsightedness) and astigmatism. READ MORE ABOUT THE TOPIC

Simple vision tests can predict which people with Parkinson’s disease will develop cognitive impairment and possible dementia 18 months later, according to a new study by UCL researchers. The study, published in Movement Disorders, adds to evidence that vision changes precede the cognitive decline that occurs in many, but not all, people with Parkinson’s. READ FULL…

An international research team of scientists from Singapore’s Agency for Science, Technology and Research (A*STAR), the Icahn School of Medicine at Mount Sinai in New York and Germany’s Eye Clinic Sulzbach is using a type of stem cell in the eye to grow the pigmented layer of retina that’s essential for vision. The approach is…
Read MoreA number of approaches to relieving the symptoms of presbyopia are now in the pipeline
The race to find a treatment for presbyopia—or at least its symptoms—continues unabated. Monovision, in which one eye is given a distance focus and the fellow eye a slightly nearer focus, has been a popular way to address this for many years. That’s been true in part because the alternatives (multifocal intraocular lenses, for example)…
Read MoreAn Innovative Treatment for Dry Eye Disease
Using artificial tears without success? Cequa increases tear production in dry eye disease (DED) patients. It’s delivered via nanomicellar (NCELL) technology, which helps to improve the bioavailability and physicochemical stability of cyclosporine. Cequa is made for the long-term treatment of DED. It addresses the inflammatory component of the disease by helping patients produce more tears…
Read MoreThe red and green specialists: why human colour vision is so odd
Fascinating article from The Atlantic giving an in-depth overview of the complexity of human vision when it comes to color. “Our own vision does not have this even spectral spacing (fig. 3). In humans and other catarrhines, the red and green cones largely overlap. This means that we prioritise distinguishing a few types of colours really…
