These WorldFamous companies advertise that their lenses can control myopia for kids, NOT adults. But none of these lenses are approved by FDA. I asked my optometrist why merely kids, not adults. But I could not understand his abstruse explanation at all! Can you please explain like I'm 5?

Essilor Stellest lenses slow down myopia progression by 67% on average, compared to single vision lenses, when worn 12 hours a day*.

  • Compared to single vision lenses, when worn 12 hours a day. Two-year prospective, controlled, randomized, double-masked clinical trial results on 54 myopic children wearing Stellest lenses compared to 50 myopic children wearing single vision lenses in China. Efficacy results based on 32 children who declared wearing Stellest lenses at least 12 hours per day every day.

Hoya MiyoSmart "corrects the visual defect on its entire surface and has a ring shaped treatment area to slow down myopia progression." Scroll down to see

ZEISS MyoKids "help with managing the progression of myopia as compared to standard single vision lenses."

"Unlike traditional single vision lenses, ZEISS MyoVision Pro has a positive effect, assisting with myopia management in children between six and 12 years old9 – with maximum visual comfort, since ZEISS MyoVision Pro spectacle lenses are also customised to match your child's anatomy and lifestyle."

Kids' eyeballs are still growing, so there is opportunity to steer them into growing to a less myopic final result.
