Abstract

Student myopia correction glasses, comprising an eyeglass frame (1) and eyeglass temples (2); upper eyeglass lenses (3) and lower eyeglass lenses (4) are provided in the eyeglass frame (1); the upper eyeglass lenses (3) and the lower eyeglass lenses (4) are spliced together; blue light preventative coatings are provided on the upper eyeglass lenses (3) and lower eyeglass lenses (4); and the maximum longitudinal length H of the lower eyeglass lenses (4) and the maximum longitudinal length h of the upper eyeglass lenses (3) satisfy: H-h＝3- 6mm. The upper eyeglass lenses (3) and the lower eyeglass lenses (4) are made of vacuum coating resin eyeglass lenses. The coating of the eyeglass lenses can reduce the glare and diffuse reflection generated by a background light source, thereby reducing the interference of various kinds of stray light on the retina, and while ensuring alternative radiation block, reducing chromatic aberration.

Description

Student myopia correction mirror

Technical field

The invention belongs to the field of vision correction glasses, and in particular relates to a student myopia correction mirror.

Background technique

Blue light radiation does not refer to blue light, but high-energy visible light with a wavelength of 400-500 nm, which is the most energetic light in visible light. High-energy blue light is an important part of visible light. It has a short wavelength and high energy. It can directly penetrate the crystal and directly on the retina of the fundus. The damage to the glasses is 10 times that of ordinary light.

Blu-ray is abundant in computer monitors, fluorescent lamps, mobile phones, digital products, displays, LEDs, notebooks, etc., and even the sunlights are hidden everywhere. At present, the time for children and young people to contact electronic products is gradually increasing. Therefore, the various radiations of electronic products seriously harm the physical health of people who come into contact, especially the damage to glasses, which is the most prominent problem that currently jeopardizes the health of primary and middle school students in China. This number will be further expanded without effective intervention. In summary, I designed a student myopia correction mirror.

The invention is achieved by the following technical solutions:

A student myopia correction mirror, comprising a frame and a temple; the frame is provided with an upper lens and a lower lens; the upper lens and the lower lens are spliced up and down; and the upper lens and the lower lens are provided with anti-blue light Coating; the longitudinal maximum length H of the lower lens is equal to the longitudinal maximum length h of the upper lens; Hh = 3 to 6 mm.

As a further optimization of the present invention, the upper lens and the lower lens have a refractive index n=1.49-1.9.

As a further optimization of the present invention, the upper lens and the lower lens are composite curved lenses formed by combining a curved prism with a thick end and a convex lens at one end.

As a further optimization of the present invention, the intersection of the upper lens and the lower lens is a straight line, and the distance from the optical center W of the upper lens is 2-6 mm.

As a further optimization of the present invention, the prisms of the upper and lower lenses in the area of use are 1.1 to 9.1 Δ.

As a further optimization of the present invention, the thickness of the thinnest side of the upper lens is b1 = 1 to 3 mm; the thickness of the thickest side of the upper lens is a1 = 4 to 8 mm; and the thickness of the lower lens is the thinnest. The thickness b2 of the side is 1 to 3 mm; the thickness a2 of the thickest side of the lower lens is 4 to 7 mm.

As a further optimization of the present invention, the intersection of the upper lens and the lower lens is an arc, and the distance between the end of the arc and the optical center W of the upper lens is 2-6 mm.

As a further optimization of the present invention, the magnet is cylindrical in shape and fixed by a magnet mount mounted on the base; the magnet is exposed at the bottom of the toy vehicle body.

Compared with the prior art, the invention has the beneficial effects that the invention can help the adjustment of the lens, the ciliary body and the ocular muscle in the eye by the combination of the upper lens and the lower lens, and reduce the inner self of the eye. Regulation and collection, and to reduce eye fatigue, so that the inhibition of myopia increases, prevention, treatment of pseudo myopia and correction of internal and external strabismus is more obvious, young people and children in learning and life, unconsciously can achieve prevention and The efficacy of treatment. The anti-blue light lens provided in the invention is made of vacuum-coated resin lens, and the coating film can effectively block harmful electromagnetic waves such as computer television, and the filter layer can protect the glasses for a long time, keeping the field of vision clear and bright. The lens coating technology can reduce the glare and diffuse reflection generated by the background light source, thereby reducing the retinal interference of various kinds of stray light time, and reducing the chromatic aberration while ensuring the alternating radiation block.
