Problems solved by technology

Existing peripheral defocus spectacle lenses adopt peripheral circular defocus and equal correction, which cannot eliminate or reduce the hyperopic defocus difference around the nasal and temporal retina, and also produce new hyperopic anisometropia around the nasal and temporal retina

Embodiment Construction

[0049] The purpose of the present invention is to provide a peripheral defocused microlens spectacle lens with large relative convex lenses on the nasal side and temporal side, low astigmatism, high quality, and high wearing compliance through the following specific implementation methods.

[0050] Meanings of terms in this manual:

[0051] The shape of the top of the boundary line of the spectacle lens: according to the position of the top of the boundary line, it is divided into different shapes. Line-shaped, dome-shaped and arc-top-shaped dividing lines are also called arc-top shapes.

[0052] Microlenses microlenses are optical components. The same microlenses are arranged on a plane at a certain period to form a microlens array. In order to reduce the size of the microlens and the microlens array, the diameter of the independent microlens can be set to millimeters, Micro- and nano-scale, microlens arrays form optical elements.

Abstract

The invention, which belongs to the technical field of spectacles, relates to a micro-lens peripheral out-of-focus spectacle lens. The spectacle lens is provided with a central correction area, a nasal side micro-lens area, a tempora side micro-lens area and a lower side micro-lens area. A gradient micro-lens area and a total micro-lens area with different refractive powers are arranged at each ofthe nasal side micro-lens area and the tempora side micro-lens area. Or the spectacle lens is provided with a central correction area and an annular micro-lens area; annular micro-lens area is provided with a gradient annular micro-lens area and a total annular micro-lens area with different refractive powers; or an annular lower side micro-lens area is arranged in a lower side area of the annular micro-lens area. Each micro-lens area is composed of a plurality of mutually independent micro-lens arrays; at least two or more than two micro lenses in the micro-lens array area have different refractive powers, shapes and radial lengths; and the independent microlenses are convex lenses relative to the central correction area, the radial length is 0.2 to 4.5 mm, and the distance between the two adjacent microlenses is 0.1 to 0.4 mm.

Description

technical field [0001] The invention belongs to the technical field of eyeglasses, and specifically provides a microlens spectacle lens for correcting myopic central myopic defocus of myopic eyes and correcting hyperopic defocus of myopic nasal and temporal retinal periphery. Background technique [0002] Myopia is a global social problem and medical problem. Peripheral hyperopic defocusing of the retina is the core mechanism of myopia pathogenesis. Peripheral defocusing spectacle lenses are the mainstream corrective spectacle lenses. The Chinese patent discloses microlens spectacle lenses that use microlens arrays to form the peripheral area of ​​spectacle lenses to correct hyperopic defocus around the retina of myopia. [0003] TAG Heuer Lens Thailand Co., Ltd. discloses a patent titled "spectacles", which uses a microlens array to form a peripheral 360° area to correct hyperopic defocus around the retina of myopia. The application date is November 29, 2013, and the patent...
