Abstract: An optical lens for a human eye is disclosed herein. In a described embodiment, the optical lens is in the form of a contact lens 100 which comprises a plurality of alternating optic zones 102 arranged between a centre 104 and a periphery 106 of the contact lens 100. The alternating optic zones 102 include a plurality of annular vision correction regions CZ1CZ5 having first refractive powers for correcting myopic refractive errors to create a focused retina image. The first refractive powers are more hyperopic at the lens' periphery 106 than at the lens' centre 104. The optic zones 102 further includes a plurality of annular vision defocus regions DZ1DZ5 having second refractive powers for creating a defocused retina image, wherein the plurality of annular vision defocus regions (DZ1DZ5) are arranged to alternate with respective ones of the plurality of annular vision correction regions (CZ1CZ5). With such a configuration, the contact lens 100 is useful for slowing myopia progression.
公开了一种用于人眼的光学镜片。在所描述的实施例中,光学镜片为隐形眼镜100的形式,隐形眼镜100包括多个交替光学区域102,该多个交替光学区域102布置于隐形眼镜100的中心104与外周106之间。交替光学区域102包括多个环形视觉矫正区域CZ1CZ5,其具有用于矫正近视屈光不正的第一屈光力,以产生聚焦视网膜图像。相较于在镜片的中心104处的第一屈光力,在镜片的外周106处的第一屈光力为较远视的。光学区域102进一步包括多个环形视觉散焦区域DZ1DZ5,其具有用于产生散焦视网膜图像的第二屈光力,其中多个环形视觉散焦区域(DZ1DZ5)布置为分别与多个环形视觉矫正区域(CZ1CZ5)交替。通过该配置,隐形眼镜100有利于减缓近视加深。
