"myopic defocus is already in use in the US with a contact lens, “MiSight® 1 day” by CooperVision, which is U.S. Food and Drug
Administration (FDA) approved to slow the progression of myopia. This product, which uses multifocal contact lens technology,
passively stimulates the entire peripheral retina with light myopically defocused by the non-central power of the contact lens. Kubota
Glasses technology leverages nanotechnology in its electronic glasses-based device and seeks to reduce the progression of myopia by
actively stimulating the retina for shorter periods while maintaining high-quality central vision and not affecting daily activities."
Which seems to indicate the main beneficiaries will be children, to slow the progression of myopia. As it mentions, there are already multi-focal contact lenses used for that purpose.
Since the contacts don't seem to be marketed at adults, I suspect this will be similar.
Assuming this device is actually legit (I'm skeptical...), it would need e.g. FDA approval to be used in the USA, correct?
