Myopia typically begins in childhood, which is why students often complain that they can’t see the whiteboard or a screen clearly. Now, a recent study published in JAMA Ophthalmology has tested whether special lenses could slow the progression of pediatric nearsightedness.

Researchers conducted a two-year randomized clinical trial in which children ages 6 to 12 across the U.S. with myopia were given a highly aspherical lenslet (HAL), which combines two functions in one design: a single-vision zone that corrects refractive error and a myopia-control zone made up of 11 contiguous HAL rings.
