Vision

Cataracts are one of the most common forms of vision impairment, and unfortunately surgery is the only real treatment. But the clouds may be parting on a new drug treatment, improving the vision of the majority of mice it was tested on.
-
Scientists have found that an existing drug, already used in humans, could help restore vision lost to conditions like age-related macular degeneration and retinitis pigmentosa. The discovery could also lead to a whole new class of drugs.
-
We've looked at many studies and research prototypes demonstrating how contact lenses could be used for more than correcting vision, and a new approval from the FDA has now cleared the way for use of the world's first drug-delivering contact lens.

If mosquitoes seem to love you but ignore the person sitting next to you, the color of your clothes might be to blame. New experiments reveal that certain colors attract hungry mosquitoes, which could be used to design new traps or repellents.

The first FDA-approved eye drops to treat age-related blurry near vision (presbyopia) has gone on sale in the US, offering a potential alternative to reading glasses for the estimated 128 million Americans affected by this common condition.
-
When astronauts stay in outer space for extended periods, they frequently develop a vision problem known as spaceflight-associated neuro-ocular syndrome (SANS). Scientists are now trying to keep that from happening, via a vacuum-sealed sleeping bag.
-
As we age, our eyesight naturally declines, but a new study has found just three minutes of exposure to 670-nanometer red light in the morning can help deteriorating vision, improving color contrast vision by nearly 20 percent.
-
Given the fact that they live in an environment full of brown tree trunks and green leaves, giant pandas' black-and-white coloration may seem counterintuitive. According to a new study, however, it really does help them blend into their surroundings.
-
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.
-
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.
-
In a major breakthrough for regenerative medicine, scientists have partially restored vision in a blind man using an emerging technique called optogenetics, which enabled the patient to locate and identify objects for the first time in decades.

We all know exercise is good for us, but recently, scientific studies have started to shine a light on how regular physical activity can benefit human health in ways you might not expect. Let's take a look at some interesting examples.
