Myopia, or nearsightedness, is a common eye condition in which you can see objects near to you clearly, but objects farther away are blurry. To see the farther clearly, you have the option of wearing eyeglasses, or undergoing the more invasive refractive surgery（屈光手术）
But Japan's Kubota Pharmaceutical Holdings claims to have developed smart glasses that, if worn just an hour per day, can cure myopia. It projects an image onto the wearers' retina（视网膜） to correct the refractive error that causes nearsightedness. Obviously, wearing the device 60 to 90 minutes a day corrects myopia.
So how does the technology developed by Kubota work exactly? Well, according to a company press release from December of last year, the special glasses rely on micro-LEDS to project virtual images on the visual field to make the retina active. Apparently, it can do that without affecting the wearer's daily activities.
Founded by Dr. Ryo Kubota, Kubota Pharmaceutical Holdings is still testing the device, known as Kubota Glasses, and trying to determine how long the effect lasts after the user wears the device. And how much the ugly-looking glasses have to be worn for the correction to be permanent.
Kubota Pharmaceutical Holdings began testing the glasses in the summer of last year, and is currently conducting tests on about 25 people in the U. S to assess the effectiveness of its smart lasses. The company plans to begin selling the device in Asia the second half of 2021 where there are more nearsighted people, but it has plans to enter other markets in the future.
