Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of lens, concretely relates to a myopia prevention and control resin lens. BACKGROUND

[0002] Peripheral defocus lens reduces the elongation of the eye axis by reducing the peripheral hyperopia defocus of the retina. The peripheral retina of the ordinary lens (single lens) will appear hyperopia defocus, that is, the peripheral focal point falls behind the retina. The defocus lens can change the peripheral hyperopia defocus of the retina into myopia defocus, thereby inhibiting the growth of the eye axis to control the degree. However, because the peripheral defocus effect of the peripheral defocus lens acts on the eyeball, the eyeball movement and the myopia control effect have certain correlation. When reading or writing for a long time, the eyeball deviates downward, and during daily activities, the eyeball is mostly directed forward or left and right. If the defocus area of the defocus lens can be improved for different use scenarios, it will inevitably have a different effect on myopia prevention and control. SUMMARY

[0003] Therefore, the utility model wants to solve the technical problem, provides a myopia prevention and control resin lens, solves the problem that the defocus area of the defocus lens in the prior art is single and lacks the lens used in different scenarios.

[0005] Further, the defocus area is annular, the first defocus area and the second defocus area are divided by an arc, and the arc opening is tangent to the edge of the central clear area.

[0006] Further, the first defocus area has a first microlens group ring, a second microlens group ring and a third microlens group ring and is arranged from inside to outside in sequence, the first microlens group ring is arranged in a microlens strip annular array, the second microlens group ring is arranged in an alternating annular array of two microlens patterns, and the third microlens group ring is arranged in a microlens triangular annular array.

[0007] Further, the second defocus area is formed by a plurality of microlenses distributed at equal intervals, and the edge distance between two microlenses is less than or equal to the diameter of the microlens.

[0008] Compared with the prior art, the present application can obtain the following technical effects:

[0009] The utility model discloses a kind of myopic prevention and control resin lenses, including: substrate;The front surface of substrate is equipped with Central Clear Zone 1, the periphery of Central Clear Zone 1 is equipped with Off-Focus Zone 2, Off-Focus Zone 2 periphery is equipped with cutting area 3, Off-Focus Zone 2 is divided into first Off-Focus Zone 4 and second Off-Focus Zone 5, first Off-Focus Zone 4 is located in Central Clear Zone 1 upper region and left and right region, and second Off-Focus Zone 5 is located in Central Clear Zone 1 lower region.
