Description

Peripheral micro-lens based vision control lens and glasses

Technical Field

The invention relates to the technical field of myopia lenses, in particular to a vision control lens based on peripheral micro lenses and glasses.

Background

Myopia, which means that the image of a target at a distance is focused in front of the retina, resulting in a blurred far vision. The existing simple and effective method is to wear a concave lens, i.e. spectacles for myopia, to spread the light rays and thereby focus them on the retina.

However, for children, the eyeball is in the development stage, if the children gradually become short-sighted due to poor reading habits, the optical focus of the peripheral part of the short-sighted lens is located at the backward position of the retina, as shown in fig. 1, the eye axis is forced to be lengthened to receive the part of visual information, vicious circle is easily formed on the physiology of the eyeball, the eye axis is further stretched, and the vision is further seriously degraded. At present, common spherical and aspherical myopia glasses are available in the market, and the common spherical and aspherical myopia glasses do not have the function of preventing myopia from deepening.

However, the technical solutions claimed in the claims of the present invention can be implemented without these technical details and with various changes and modifications based on the following embodiments.

The embodiment of the invention relates to a vision control lens based on peripheral micro-lenses, which is shown in a combined figure 2 and comprises a lens body 10, wherein the lens body 10 sequentially comprises a central fixed light area 11 and a peripheral light area 12 from inside to outside; the central fixed light area 11 is located at the central position of the lens body 10, and the peripheral light area 12 is provided with an out-of-focus micro lens 13.

The central fixed optical zone 11 is a conventional concave lens or a portion of a concave lens that can match the myopic power of the patient's eye such that the central optical focus falls on the retina;

in a preferred embodiment, the diameter of the central fixed light zone 11 is 8-10mm in practical use;

referring to fig. 2, the defocused micro-lens 13 is a convex lens, and is circumferentially distributed in the peripheral light area 12 in 360 degrees and is distributed over the peripheral light area 12; thus, by arranging the defocused micro lens 13 on the peripheral light area 12, the focus of the peripheral light area 12 of the lens body 10 can fall on the retina or in front of the retina, so that the stretching growth of eyeballs is avoided, and the further deepening of the myopia of the eyes is effectively slowed down.

Preferably, the diameter of the defocused microlens 13 is 1-5 mm.

In another embodiment, referring to fig. 3, the lens includes a lens body 10, and the lens body 10 includes, from inside to outside, a central fixed light region 11, a gradual change light region 14, and a peripheral light region 12 in sequence; the central fixed light area 11 is located at the central position of the lens body 10, and the peripheral light area 12 is provided with an out-of-focus micro lens 13.

In a preferred embodiment, the central fixed light zone 11 has a diameter of 8-10 mm;

in a preferred embodiment, the graded light region 14 has a diameter of 10 to 30 mm;

the power difference between the power of the gradual change light area 14 and the power of the central fixed light area 11 is a curvature change value, the power of the lens body is equal to minus 60 degrees, the power of the lens body is equal to minus 50 to minus 100 degrees, the curvature change value is equal to plus 70 degrees, the power of the lens body is equal to minus 125 to minus 400 degrees, the curvature change value is equal to plus 80 degrees, the power of the lens body is equal to minus 425 to minus 600 degrees, the curvature change value is equal to plus 90 degrees, and the power of the lens body is less than minus 625 degrees, and the curvature change value is equal to plus 95 degrees.

Through the gradual change light zone 14 and the focusing micro-lens 13 arranged on the peripheral light zone 12, the optical focus of the peripheral light zone can fall on the retina or in front of the retina as far as possible, and the further deepening of the myopia of the eye can be effectively slowed down.
