The optical lens comprises an optical lens base body 10, a far vision area 11, a middle vision area 12, a near vision area 13, an upper arc line 20, a lower folding line 30, a lower concave lens part 41, a prism part 42 and an optical center O.

Detailed Description

Embodiments of the present application will be described in detail with reference to the drawings and examples, so that how to implement technical means to solve technical problems and achieve technical effects of the present application can be fully understood and implemented.

Referring to fig. 1 and 2 together, fig. 1 is a side view of a high-protection ophthalmic lens for correcting juvenile eyesight according to an embodiment of the present application; fig. 2 is a top view of a high protective juvenile vision correcting ophthalmic lens of an embodiment of the present application. As shown in the drawings, an ophthalmic lens for highly protective juvenile vision correction includes an optical lens base 10 with refractive power, the optical lens base 10 having a distance vision zone 11 at an upper end, a near vision zone 13 at a lower end, and a middle vision zone 12 between the distance vision zone 11 and the near vision zone 13; wherein, the far vision zone 11 and the middle vision zone 12 are divided by an upper arc line 20, the middle vision zone 12 and the near vision zone 11 are divided by a lower broken line 30, and the optical center O of the optical lens substrate 10 is positioned in the middle vision zone 12.

In one embodiment of the present invention, the optical lens base 10 is made of resin or glass, and is divided into a distance vision area 11, a middle vision area 12, and a near vision area 13 from the top down, and the distance vision area 11 is located on the upper side of the optical lens base 10 for overlooking a distant place. The intermediate viewing zone 12 is located in a central region of the optical lens substrate 10 for capturing intermediate distance views, such as blackboards, televisions, and the like. And the near vision zone 13 is positioned at the lower end of the optical lens substrate 10 and is used for reading and writing, so that the requirement of a shorter distance visual field is met. Wherein the far vision zone 11 and the intermediate vision zone 12 are demarcated by an upper arc 20, and the intermediate vision zone 12 and the near vision zone 13 are demarcated by a lower fold line 30.

Specifically, the far vision zone 11 is a convex lens to meet the high beam requirement, the intermediate vision zone 12 is a concave lens to meet the near vision requirement, the near vision zone 13 comprises a concave lens portion 41 extending to the intermediate vision zone 12 and a pressed prism portion 42, and light can be refracted towards the base direction through the prism portion 42, so that the strabismus correcting effect can be achieved; on the other hand, the degree can be controlled not to increase, and the naked eye vision is improved to a certain degree.

Preferably, the prism portion 42 is a prism, and is thermally pressed on the concave lens portion 41 through the PU film layer, so that the PU film layer can ensure that the thickness is not increased basically, and the usability is strong. The triple prism is widely applied and has high refraction efficiency.

The upper arc line 20 and the lower broken line 30 are symmetrical about the left and the right, the distribution is clear and uniform, and the eyeball adapts fast.

Further, the upper camber line 20 gradually approaches the optical center O from both sides, and when looking out a distance, it is possible to focus on the upper side of the optical lens base 10 with ease, thereby improving adaptability.

The lower folding line 30 has a folding line intersection point which is close to the optical center O, and preferably, the folding line intersection point is 2-4 cm away from the optical center, and is arranged lower, so that the lower folding line can be conveniently focused to the lower side of the optical lens substrate 10 when reading and writing, and the adaptability is improved.
