Myopia, also called nearsightedness or shortsightedness, is the most common vision issue among children and young adults and it’s only getting worse. Approximately 20 million children in the United States, or one in every three, suffer from myopia and recent studies show that half the world...

Myopia, also called near-sightedness, is a common eye disease, whereby objects far away appear blurry and out of focus.1 This can make it harder for your child to concentrate at school and to have a carefree experience at play. If left untreated in children, myopia can lead to significant...

Those with myopia see nearby objects clearly but distant objects appear blurred. With myopia, the eyeball...
This type of myopia, also called simple or school myopia, can be easily corrected through standard treatments, like eyeglasses, contact lenses or refractive surgery. High myopia Myopia with a refractive error of more than -6 diopters is considered high myopia. High myopia can be corrected with ...
