Description

Technical Field

[0001] The present invention relates to the technical field of spectacle lenses, and specifically refers to a dynamic alternating defocus soft light spectacle lens for preventing and delaying the development of myopia. Background Art

[0002] With the development of electronic products in recent years, people have myopia development from childhood to adulthood, and the number of myopic teenagers is increasing continuously. Myopia is getting younger, and the high myopia rate is also rising continuously. Newborn infants are hyperopic, and they become emmetropic as they grow. If the development is too fast, they will become myopic. Therefore, myopic defocus lenses are now used. By using the principle of myopic defocus, while correcting central refractive errors, the relatively positive diopters in the periphery are used to correct the peripheral retinal hyperopic defocus of myopic eyes, thereby inhibiting the axial length growth and myopia progression induced by peripheral retinal hyperopic defocus, so as to play a role in delaying the deepening of vision.

[0003] However, the defocus lenses in the prior art are basically single static signals. When worn and used for a long time, the brain will produce adaptability, thus reducing the prevention and control effect. The filling rate of the defocus prevention and control functional area determines the prevention and control effect. Most of the existing defocus lenses use dot-shaped prevention and control units, and there is still room for improvement in the filling rate of the prevention and control functional area.

[0018] An annular dynamic alternating defocus area 4 is provided outside the central optical correction area 2 of the lens body 1. Nine defocus rings are provided in the annular dynamic alternating defocus area 4. The width of each defocus ring is set to be 0.5 mm to 1 mm. The defocus diopter range is set to be +12.00D to -12.00D, and a spherical lens or a cylindrical lens is used. A first soft light microstructure area 3 is filled between the central optical correction area 2 and the nine defocus rings in pairs. A second soft light microstructure area 5 is provided outside the annular dynamic alternating defocus area 4 of the lens body 1. The width of the first soft light microstructure area 3 is set to be 0.5 mm to 1 mm, and the width of the second soft light microstructure area 5 is set to be 0.5 mm to 2 mm outside the annular dynamic alternating defocus area 4. The central optical correction area 2, the first soft light microstructure area 3, the annular dynamic alternating defocus area 4, and the second soft light microstructure area 5 form a functional area.

[0019] Example 1 is a positive and negative alternating defocus lens:

[0020] The widths of the first, third, fifth, seventh, and ninth defocus rings in the annular dynamic alternating defocus area are 0.5 mm to 1 mm, and the diopter is set to be +2.00D to +12.00D. The widths of the second, fourth, sixth, and eighth defocus rings are 0.5 mm to 1 mm, and the diopter is set to be -2.00D to -12.00D. The width of the first soft light microstructure area is set to be 0.5 mm to 1 mm, and the width of the second soft light microstructure area is set to be 0.5 mm to 2 mm.

[0021] Example 2 is a negative and positive alternating defocus lens:

[0022] The widths of the first, third, fifth, seventh, and ninth defocus rings in the described annular dynamic alternating defocus area are set to be 0.5 mm to 1 mm, and the diopter is set to be -2.00D to -12.00D. The widths of the second, fourth, sixth, and eighth defocus rings are set to be 0.5 mm to 1 mm, and the diopter is set to be +2.00D to +12.00D. The first soft light microstructure area is set to have a width of 0.5 mm to 1 mm, and the second soft light microstructure area is set to have a width of 0.5 mm - 2 mm.

[0023] Example 3 is a negative defocus lens:

[0024] The widths of the nine defocus rings in the described annular dynamic alternating defocus area are all 0.5 mm to 1 mm, and the diopter is set to be -2.00D to -12.00D. The first soft light microstructure area is set to have a width of 0.5 mm to 1 mm, and the second soft light microstructure area is set to have a width of 0.5 mm - 2 mm.

[0025] Example 4 is a positive defocus lens:

The first soft light microstructure area is set to have a width of 0.5 mm to 1 mm, and the second soft light microstructure area is set to have a width of 0.5 mm - 2 mm.

[0027] In this application, by setting an annular dynamic alternating defocus area 4 and a soft light area on the lens body 1, when light passes through the annular dynamic alternating defocus area 4, the converging and diverging state of the light will change, so that after it enters the eyeball, it cannot form a high-definition visual signal on the retina, thereby weakening the visual development stimulation of the peripheral retina, reducing the participation of accommodation, reducing the thinning of the choroid, and avoiding insufficient blood supply to the sclera. When light passes through the soft light area, the light transmittance is purposefully interfered, and the brightness and contrast are comprehensively reduced by 30% or more, thereby purposefully reducing the contrast intensity of the visual signal entering the eye, decreasing the recognition ability of the peripheral retina for high-spatial-frequency images, thus avoiding frequent stimulation of the peripheral retina by high-contrast signals, slowing down the consequence of rapid posterior growth of the eye axis, and also effectively preventing the occurrence of myopia and delaying the progression speed of myopia.

[0028] The above describes the present invention and its implementation manners. This description is not restrictive, and the actual structure is not limited thereto. Generally speaking, if those of ordinary skill in the art are inspired by it and design similar structural manners and embodiments without creative efforts without departing from the gist of the present invention, they shall fall within the protection scope of the present invention.
