Progress of Frame Glasses Based on Peripheral Defocus Theory in the Prevention and Control of Myopia in Adolescents and Children
Myopia has become a global public health problem,which affects people's quality of life to varying degrees.The emergence of the theory of retinal peripheral defocus provides a new idea for the prevention and control of myopia.Progressive addition lenses,defocus incorporated multiple segment,highly aspherical lenslet target,diversified segmental defocus optimization,peripheral defocus modifying lenses,full focus lenses and ring focus lenses play important roles in the prevention and control of myopia in adolescents and children by using the theory of peripheral defocus of the retina to correct peripheral hyperopic defocus of the retina,thereby delaying the development of myopia and axial length growth.This article will review the application progress of the above seven defocus lenses in the correction of myopia in adolescents and children.
