As people age, their eyes lose the ability to focus on close objects. A new eye drop treatment called Vuity can improve vision without the need for glasses, contacts or surgery.
Orthokeratology involves wearing a specially designed rigid contact lens overnight. There’s good evidence it can help slow the progression of myopia. But like all treatments, there are risks, too.
To tell you the truth, nobody really knows. But it’s probably got to do with the fact that signals from your nose and your eyes arrive in the same area of your brain.
‘Worm’ is really a catchall term for a huge variety of animals with different characteristics that span the tree of life. They hold clues about our own origins as well as hints about human health.
Our study on weird ancient marine animals called radiodonts supports the idea that vision played a crucial role during the Cambrian Explosion, a rapid burst of evolution about 500 million years ago.
Having longer top eyelashes can enhance our ability to express our feelings and communicate with others. But the most significant reason we have them is to protect our eyes.
With caregivers’ faces covered, infants and young children will miss out on all the visual cues they’d normally get during stages of rapid developmental growth.
With online learning and social distancing, kids are spending more time staring at screens and less time outdoors. That can put them at higher risk of myopia and serious eye problems in the future.
It takes time for information from our eyes to reach our brains and become part of our conscious experience. So our brains use predictions to make up the delay.
