Step-by-step explanation:
A popular multifocal soft contact lens not available in the US that is used for myopia control is Miyosoft. This lens is designed to slow the progression of myopia in children and young adults by focusing light in a way that discourages the elongation of the eyeball. Nearsightedness (myopia) is a common vision condition in which near objects appear clear, but objects farther away look blurry. It occurs when the shape of the eye — or the shape of certain parts of the eye — causes light rays to bend (refract) inaccurately. Although Miyosoft is mentioned as an option, it's important to consult with an eye care professional to explore the most suitable choices for myopia control, as products and availability may differ by region.
