- Abstract: Myopia is becoming more and more common all over the world, and the incidence of myopia is gradually increasing. Many treatments have been used to prevent and control myopia, including optics, drugs, environment or behavior, but the results are different and lack standardization. At present, many experiments have proved that peripheral defocus technology has a certain effect on myopia control. Based on this technology, three kinds of framed eyeglass lenses with peripheral defocus design, namely defocus incorporated multiple segments(DIMS), highly aspherical lenslets(HAL)and cylindrical annular reactive elements(CARE), are commonly used in medical and optometry institutions in China. These lenses provide not only clear vision in the central area, but also a certain amount of myopic defocus in the periphery to control the progression of myopia. This paper aims to focus on the design principle and myopia prevention and control effect of the above three peripheral defocus lenses, and evaluate their effectiveness in clinical practice.
