Myopia (nearsightedness, where distance vision is blurry) is growing at an alarming rate, with 1 in 3 U.S. children now myopic. Researchers believe that the environment kids grow up in today, with too many close distance activities (like reading and device use) and lack of outdoor play is contributing to the rapid increase in childhood myopia. While glasses and contact lenses compensate for a child’s blurry distance vision, they don’t stop your child’s vision from continuing to deteriorate. As children grow, myopia often develops as they reach school age and, untreated, progresses into the late teens.
