The idea is to treat nearsightedness in children, rather than just correcting it.
Ask anyone about the benefits of technology and it probably won’t take them long to rhyme off a list of examples: it helps broaden your knowledge, connect with friends, both new and old, and allows you to see things you’ve never seen before.
But what about the drawbacks? Here’s a major one: increased screen time is hard on your eyes.
Nearsightedness, or myopia, is increasing at an eye-popping rate. By 2050, scientists predict more than 4.7 billion people, roughly half of the global population, will be nearsighted.
Beyond corrective eyeglasses and contact lenses, there has been little parents can do for nearsighted children. Now optometrists like Dr. Liu are offering a treatment called orthokeratology — ortho-k, for short.
Strong correlations were found between current eyesight and volunteers’ lifetime exposure to sunlight, above all UVB radiation (which is responsible for burning). Those who had gotten the most sun, particularly between the ages of 14 and 19, were about 25 percent less likely to have developed myopia by middle age.
Your eyes aren’t broken. Myopia isn’t a mysterious illness. There is pseudo myopia (a strain symptom), and progressive myopia (a lens-created stimulus).
Why did myopia increase by 66 percent between the early 1970s and the early 2000s?
Lying on the back while reading may slow the progression of the eye condition in young people, a study suggests.
To battle an explosion of myopia, eye researchers try more outdoor time, medication, even a giant, translucent cube.
The projected increase in nearsightedness, the authors wrote, is “widely considered to be driven by environmental factors (nurture), principally lifestyle changes resulting from a combination of decreased time outdoors and increased near work activities, among other factors.” Family history also is a factor.
If you're reading this, there's a good chance you spend much of your working day and leisure time staring at a computer screen.
You probably spend less time thinking about what it's doing to your eyes.
Researchers may have found the answer that could keep glasses off one-third of the world’s population.
Researchers expect eyesight to worsen across the globe thanks to more screens and less time outdoors.
The definitive natural myopia control resource.
Most babies are born farsighted. As the eyeball lengthens with growth, the farsightedness decreases until normal vision is achieved. That is why young children often leave the eye doctor with a diagnosis of developmental hyperopia, or hyperopia appropriate for age.
Hyperopia beyond that which is appropriate for age often runs in families.
