Final answer:
The MiSight Lens is a soft contact lens that corrects myopia by providing power in the center and myopic defocus in the periphery. Clinical trials have shown that it can slow down the progression of myopia.
Step-by-step explanation:
The MiSight Lens is a type of lens that is used to correct myopia, also known as nearsightedness. It is a soft contact lens that has a concentric dual-focus design, which means that it corrects myopia by providing power in the center of the lens and myopic defocus in the periphery of the lens. This design helps to slow down the progression of myopia.
The evidence that the MiSight Lens works comes from several clinical trials. One study found that wearing the lens for at least 6 hours a day slowed down the progression of myopia by 59% over a three-year period compared to wearing regular single-vision contact lenses. Another study showed that the lens reduced the rate of axial elongation, which is associated with myopia progression, by 52% over a two-year period compared to wearing regular single-vision contact lenses.
