Problems solved by technology

However, the dual-light polarizing film optical lens of this patent is obviously mainly suitable for use in outdoor occasions. When used in indoor occasions, because the indoor light is not as strong as the outdoor light, the polarizing film of the double-light polarizing film optical lens will block more light. It is only suitable for indoor short-term wearing, not long-term wearing
[0003] However, based on the existing technology, people with presbyopia only need to wear a pair of glasses to see both nearby objects and distant objects, and most of the time they wear them indoors, and occasionally they can also wear them outdoors. However, this demand is currently not met

Embodiment Construction

[0015] The present invention will be further described in conjunction with the accompanying drawings and specific embodiments.

[0016] refer to figure 1 , figure 2 and image 3 As shown, the optical lens shown in this embodiment includes: an optical lens 1 in the shape of an arc surface and a layer of color-changing film; the color-changing film 2 is attached to the convex surface of the optical lens 1 (see figure 2 and image 3 As shown), the optical lens 1 and the color-changing film 2 are integrally formed and bonded together. For example, the color-changing film 2 is positioned at the bottom of the mold, and then the two are firmly bonded by plastic injection and integrally formed. Described optical lens 1 is provided with a presbyopia viewing area 101 near the position below (referring to figure 1 shown). Corresponding to the presbyopic viewing area 101, the curved concave surface of the optical lens 1 is provided with a convex edge 1011 and is connected to the p...

Abstract

The invention relates to an optical lens, in particular to a bifocal lens with a color shift film. The optical lens comprises an optical lens body with an arc-surface shape and a layer of color shift film, wherein the color shift film is attached to the arc convex surface of the optical lens body; the optical lens body and the color shift film are integrally formed; a presbyopia visual region is arranged at a position, which is close to the lower side, of the optical lens; a flange corresponding to the presbyopia visual region is arranged on the arc concave surface of the optical lens body and is connected to the peripheral edge through a smooth gradually-changed arc surface; meanwhile, the presbyopia visual region is directly formed by performing injection molding on the optical lens body. The optical lens is suitable for being worn by presbyopia people in a room and in the open air, and has a blue ray resisting function.

Description

technical field [0001] The invention relates to the field of optical lenses, in particular to a bifocal lens with a color-changing film, which is used for reading in various occasions. Background technique [0002] In order to solve the problem of older people who have presbyopia but hope to see both nearby objects and distant objects clearly by wearing a pair of glasses, a patent publication No. 202133833U discloses a dual-light polarizing film optical lens to It is provided for people with presbyopia to wear when doing outdoor activities or driving. However, the dual-light polarizing film optical lens of this patent is obviously mainly suitable for use in outdoor occasions. When used in indoor occasions, because the indoor light is not as strong as the outdoor light, the polarizing film of the double-light polarizing film optical lens will block more light. It is only suitable for indoor short-term wear, not for long-term wear. [0003] However, based on the existing tec...
