Description

Progressive multi-focus presbyopic lens

Technical Field

The utility model relates to the technical field of glasses, more specifically say, it relates to a multifocal presbyopic lens step by step.

Background

The traditional spectacle lenses are used for correcting eyesight and generally have only one focus, for example, a concave lens can correct myopia and a convex lens can correct hypermetropia. However, for some adults, the adults are originally short-sighted and become people with long-sightedness due to the age increase, when the adults look at objects, objects at far distances are clear, and when the objects are closer to the people, the objects become fuzzy, and at the moment, the convex lenses are needed to be used.

SUMMERY OF THE UTILITY MODEL

To the deficiency that prior art exists, the utility model aims to provide a make the presbyopic glasses that far and near can both be seen clearly through the luminosity district of gradual deformation.

In order to achieve the above purpose, the utility model provides a following technical scheme: a progressive multi-focus presbyopic lens comprises a circular lens, wherein a lens preparation horizontal line and a vertical symmetry axis are arranged on the lens, a light flattening area is arranged on the vertical symmetry axis and is positioned above the lens preparation horizontal line, a gap is formed between the light flattening area and the lens preparation horizontal line, a luminosity gradual change area is arranged below the light flattening area and extends to the position below the lens preparation horizontal line, the luminosity gradual change area has luminosity gradients, and the luminosity gradients are sequentially increased from top to bottom.

The utility model discloses further set up to: the flat zone is set to 0 degrees.

The utility model discloses further set up to: the photometric gradient is set at 0 to 100 degrees, 0 to 150 degrees, 0 to 200 degrees, 0 to 250 degrees, 0 to 300 degrees, 0 to 350 degrees, or 0 to 400 degrees.

The utility model discloses further set up to: the two sides of the vertical symmetry axis are provided with blind area parts, the blind area parts are arranged in an arc shape close to the center point of the lens, and the blind area parts are positioned at the edge positions of the two sides of the lens.

The utility model discloses further set up to: the lens material is polymethyl methacrylate or polycarbonate.

Through adopting the technical scheme, the utility model discloses a presbyopic glasses enable the person of wearing when wearing and can both obtain clear vision from far point to near point, form the visual effect of far and near clear from top to bottom, make and wear more comfortable, need not dispose many pairs of glasses, convenience more.

Detailed Description

The embodiment of the present invention will be further explained with reference to fig. 1.

The utility model discloses a progressive multifocal presbyopic lens, including circular shape lens 1, set up lens horizontal line 2 and perpendicular symmetry axis 3 on the mirror, be equipped with flat light zone 4 on the perpendicular symmetry axis 3, flat light zone 4 is located lens horizontal line 2 tops, just be the clearance setting between flat light zone 4 and the lens horizontal line 2 flat light zone 4 below is equipped with luminosity gradual change district 5, luminosity gradual change district 5 extends to lens horizontal line 2 below, luminosity gradual change district 5 has the luminosity gradient, the luminosity gradient increases from top to bottom in proper order. The flat light zone 4 is set to 0 degrees. The photometric gradient is set at 0 to 100 degrees, 0 to 150 degrees, 0 to 200 degrees, 0 to 250 degrees, 0 to 300 degrees, 0 to 350 degrees, or 0 to 400 degrees. Blind area parts 6 are arranged on two sides of the vertical symmetry axis 3, the blind area parts 6 are arranged in an arc shape near the center point of the lens 1, and the blind area parts 6 are positioned at the edge positions of two sides of the lens 1. The material of the lens 1 is polymethyl methacrylate or polycarbonate.

The working principle is as follows: when people wear the lens 1 of the utility model, when people look far away, people look forward looking, people's the focus point just in time is located the ascending position in lens 1 center, see out by plano region 4, because people themselves are the presbyopia this moment, so the object of remote can be clearly seen naturally, and when the object that people will look at is from far to near, the focus point of eyes can be in plano 4 below and slowly move downwards in order to observe the object, the eyes can form the cooperation with the luminosity gradient of luminosity gradual change region 5 at this in-process, make people can be clear all the time observe the object, unusual practicality. By setting the luminosity gradient to be 0 to 100 degrees, 0 to 150 degrees, 0 to 200 degrees, 0 to 250 degrees, 0 to 300 degrees, 0 to 350 degrees or 0 to 400 degrees, people can select the corresponding luminosity gradient according to the presbyopia degree, and the method is more practical. The utility model discloses a presbyopic glasses enable the person of wearing when wearing and can both obtain clear vision from far point to near point, form the visual effect of far and near clarity from top to bottom, make and wear more comfortable, do not need dispose many pairs of glasses, convenience more.

It is above only the utility model discloses a preferred embodiment, the utility model discloses a scope of protection does not only confine above-mentioned embodiment, the all belongs to the utility model discloses a technical scheme under the thinking all belongs to the utility model discloses a scope of protection. It should be noted that, for those skilled in the art, various modifications and decorations can be made without departing from the principle of the present invention, and these modifications and decorations should also be regarded as the protection scope of the present invention.
