Find out how to Sluggish Down Myopia
Can the advance of myopia be slowed and even halted to forestall long-term problems? Tkatchenko says sure: “There’s a clearly outlined treatable interval between ages 8 and 25 throughout which there’s the best development of myopia, and myopia management is best throughout these years.”
For these identified with extreme myopia, often called excessive myopia, particular contacts worn at night time might help reshape the cornea and stabilize the attention to assist with imaginative and prescient.

“Myopia management is best when initiated as early as potential, so I’m typically recommending MiSight as quickly as a toddler matches the parameters,” Onken says. “In a toddler who will not be but nearsighted however who seems to be headed in that path, I’ll be sure that to say myopia management contact lenses to the mother and father in order that they have time to assume over it and digest the thought of placing their baby involved lenses.”
Medical doctors additionally use atropine eye drops for myopia management, however they’re additionally prescribed solely on an off-label foundation, Onken says. He solely recommends atropine eye drops earlier than MiSight contacts if children are below 4 years previous or so.
