Zusammenfassung:The lens comprises a central correction area and a peripheral defocus area, a plurality of circles of micro-lenses which are arranged in a concentric circle mode are arranged on the concave surface of the peripheral defocus area, the curvature radiuses of the micro-lenses are gradually increased from the center to the edge, and the luminosity difference of every two adjacent circles of micro-lenses is 0.25 degree. The surface of the lens is provided with a plurality of circles of micro lenses which are arranged in a concentric circle mode, the luminosity is regularly and annularly decreased from the center to the periphery, central ametropia is corrected, meanwhile, peripheral relative positive luminosity is used for correcting myopia peripheral retina hyperopia defocus, the peripheral defocus phenomenon is effectively reduced, and the myopia development speed can be slowed down. 本发明公开了一种镜片及具有其的眼镜,其中镜片包括中心矫正区和周边离焦区,在周边离焦区的凹表面设有多圈呈同心圆排列的微透镜,多圈微透镜沿中心向边缘方向的曲率半径逐渐增大,且相邻两圈微透镜的光度差为0.25度。本发明镜片表面具有多圈同心圆排列的微透镜,且光度从中心向
