Abstract

The utility model discloses a miniature lens and glasses comprising the lens. The maximum area of the lens corresponds to 2/3 of the visual field of the retina of the human eye, and the minimum area of the lens corresponds to the central macular area of the human eye. The lens performs refractive correction, foot correction or overcorrection on the central area of the human visual field, especially the macular area, and the rest of the visual field can be designed as a 0-degree lens or remove this part of the lens as a part of the bearing area. Because the area of the lens is smaller than that of the traditional lens, it can be made very thin and light, the various optical errors will be small, the irritation to the eyes and the pressure on the face are also much smaller, and it has the effect of comfort and health care. The bearing area outside the lens can be designed in different forms to achieve a significant decorative effect. Because the lens eliminates the artificial stimulation of the peripheral field of the traditional lens from defocusing the peripheral vision of the eye, it is more comfortable to wear and can improve or control the diopter of the eye. This lens and the various glasses it is made of are suitable for all eyewear families.

Description

A kind of mini-lens and glasses including the same

technical field

The utility model relates to a lens, in particular to a miniature lens for correcting ametropia of eyes and glasses comprising the lens.

Background technique

At present, in the face of eye problems such as ametropia, farsightedness, and astigmatism, the corresponding corrective lenses are myopia lenses, hyperopia lenses, astigmatism lenses, progressive multi-focal lenses, aspheric lenses, lenses that control defocus and eye diopter or combined For myopia, hyperopia, and astigmatism lenses, the lens diameters are 60mm, 65mm, 70mm, etc., and the lens diameter (or horizontal width) of the glasses made is generally more than 45mm. The entire lens covers the human eye's field of vision, including both the central field of view and most of the peripheral field of view. The lens area is large and thick. In the process of wearing glasses, it is common for the frame of the glasses to be heavy on the face. Nose pressure marks and damage.

At present, eye fatigue and dry eyes are common when wearing glasses. For the majority of teenagers, the diopter is uncontrollable. The degree of myopia increases year by year, and the development speed is very fast. When formulating the degree, the industry stipulates that all people over the age of 7 generally have a vision of 1.0 or less, and it cannot be over-equipped, let alone over-corrected (that is, over-corrected), so the corrected vision cannot reach the best vision of the human eye. 1.5 or so. Therefore, the corrected vision is bound by traditional thinking, and the glasses from the hospital to the optical shop are not corrected enough or overcorrected. They mistakenly believe that this will avoid deepening and adverse changes in the diopter, so that the ideal vision cannot be achieved with glasses. For the problem of controlling the aggravation of diopter in teenagers, the patent number: 201210196959.8 solves the bad defocus around the retina, so as to solve the problem of controlling the development of myopia and hyperopia, which can not be emmetropized. The problem that the defocusing effect of the lens area is not very comfortable enough, the corrected visual acuity of wearing is not up to the best problem, and the aesthetic problem of the preparation glasses all have some deficiencies.

Utility model content

Aiming at the problems of thick and heavy spectacle lenses, lack of wearing comfort and aesthetics, the utility model provides a light, comfortable and health-care mini lens.

The mini-lens of the utility model is much smaller than previous lenses (equivalent to the size of the central area of previous lenses), its maximum area S is _{large and} corresponds to 2/3 of the retinal field of view of the human eye, and the minimum area S of the lens is _small corresponding to the central macular area of the human eye.

The spectacle matching method of the lens of the present utility model is that the corrected degree F of the preparation satisfies the following conditions:

F=F ₀ +ΔF ₁ +ΔF ₂ ,

Among them, F ₀ is the degree of prescription for vision of 1.0 or below, ΔF ₁ is the degree of increase when the correction is sufficient, and ΔF ₂ is the degree of increase when the correction is overcorrected; the value range of ΔF ₁ and ΔF ₂ is: ΔF ₁ =± (1-50) degrees, ΔF ₂ =±(0-50) degrees, negative values for myopia and positive values for hyperopia.

In the utility model, the size of the lens is 2-43mm. 2-43mm lenses can correspond to the macular area and some peripheral areas of the human retina. In order to make the lens more practical, the size of the frame lens is preferably 5-35mm, more preferably 10-30mm, further 15-20mm. The size of the contact lens is preferably 2-6 mm, more preferably 2-5 mm, further 3-4 mm.

The lens of the utility model can be a frame type lens, a contact lens, a patch type lens or a press-fit lens. The lens can be made of any material in the prior art, preferably optical glass, resin or silicon hydrogel.

The vision of the human eye mainly depends on the central vision. For eyes with ametropia, the central vision of the retina can be corrected, but the peripheral area of the retina does not need to be corrected. It is best to keep this area in its original state. In the past, the peripheral area of the lens was given various diopters corresponding to the central area, and the diopter of the peripheral area would cause the retina in the peripheral vision of the human eye to defocus. According to modern ophthalmology research experiments, it is known that the peripheral area of the myopic lens worn by myopia leads to hyperopic defocus in the peripheral area of the retina of the eye, which will lead to the development of myopia; Myopic defocusing of the peripheral area of the retina prevents emmetropia in hyperopic eyes; this defocusing also causes artificial eye discomfort. Therefore, in the present invention, the corresponding peripheral area of the lens can be designed with a lens power of 0 or part of the lens in this area can be removed. Because the lens eliminates the artificial stimulation of defocusing on the peripheral vision of the eye, especially the equatorial area, in the peripheral area of the traditional lens, it will feel more comfortable to wear and can improve or control the diopter of the eye.

The eyeglass fitting method of the utility model for correcting eyesight adopts the method of sufficient correction or even overcorrection. This is different from any correction method in the past. In the past, glasses were under-corrected, that is, formulated as F ₀ , because for people over 7 years old, they were not corrected to the best vision, which is about 1.5, but corrected to 1.0 or below. People over the age of 7 generally have a vision of 1.5 or 2.0, so traditional glasses are undercorrected. The utility model requires the glasses to be corrected enough to F ₁ , or even over-corrected to F ₂ . Correction of the foot can make the eye achieve the best vision, and overcorrection can also achieve the best vision through the eye's own adjustment function. In addition, for amblyopia, the amblyopia can be improved by adequate correction or overcorrection of the central retinal area of the eye, especially the macular area. The result prepared by such a method conforms to the visual law (human vision can reach about 1.5), and there will be no side effects. The best eyesight is achieved, the eyes see the clearest, and people feel the most comfortable, thus achieving the purpose of health care.

The utility model also protects the spectacles containing the above-mentioned mini spectacle lens. The spectacles include the mini lens and a bearing area arranged around it, and the bearing area has no diopter. Because the lens of the present utility model is much smaller than the previous lens, the saved other areas can be made into the load-bearing area lens, picture frame, and frame of frame-type glasses of different styles, the load-bearing area lens of contact lens, and the load-bearing area of patch-type lens. Area lenses, and bearing area lenses in the form of reading and writing equipment of different styles. The shape of the carrying area is any practicable shape, preferably a circle, triangle, rhombus or rectangle, and also other irregular shapes or patterns. The material of the carrying area is any material that can be implemented, preferably a light-transmitting material or a metal material. It has a significant decorative effect on the carrying area, and can express personalization and conceptualization.

Whether it is the lenses of frame glasses or contact lenses, as well as the lenses on any equipment used for reading, writing, and viewing, they have become much smaller. Small can be made very thin and light, and various optical errors will be very small. Small, less irritating to the eyes and less pressure on the face and nose, and more comfortable to wear, with light, healthy, clear and mini effects.
