Whereas glasses, contact lenses, eye drops and surgical procedure can appropriate the consequences of myopia and permit clear distance imaginative and prescient, they deal with the signs of the situation, not the factor that causes it — a barely elongated eyeball through which the lens focuses gentle in entrance of the retina, somewhat than instantly on it.
“When the attention turns into longer, the tissue of the retina and the buildings supporting the optic nerve stretch and turn into thinner,” says Andrei Tkatchenko, MD, PhD, affiliate professor of ophthalmic sciences at Columbia College Irving Medical Heart in New York. “This thinning will increase the chance of retinal detachment, cataracts, glaucoma, and even blindness. The sooner myopia progresses and the extra the prescription will increase, the larger the chance of those ailments.”
Kids with nearsighted mother and father usually tend to be nearsighted themselves, and scientists have recognized quite a lot of myopia-related genes. However genes normally work with an individual’s setting to trigger a illness. The highest factor within the setting linked to myopia is close-up work resembling studying or engaged on a pc or good gadget. “Over the previous three a long time, the extent of close to work has considerably elevated in a lot of the world,” says Tkatchenko.
Can the advance of myopia be slowed and even halted to forestall long-term issues? Tkatchenko says sure: “There’s a clearly outlined treatable interval between ages eight and 25 throughout which there’s the best development of myopia, and myopia management is handiest throughout these years.” He and different researchers are learning new strategies for treating myopia. Multifocal contact lens have been discovered to be efficient in slowing the development of myopia in kiids. For these recognized with extreme myopia, often known as excessive myopia, specail contacts, worn at evening may also help reshape the cornea and assist stablize the attention.

However there’s one easy prescription that might defend your baby from getting myopia within the first place: spending time exterior. “Plenty of research have proven that exterior actions suppress the event of myopia,” says Tkatchenko. Scientists aren’t certain why this occurs, however one idea is that out of doors gentle stimulates the discharge of chemical substances that sign the attention to sluggish its progress to a traditional fee.
“Go exterior and play. That is one of the best factor mother and father can inform their youngsters to assist stop myopia,” says Tkatchenko.
