Lens capable of relieving discomfort of eyes

Abstract

A lens capable of relieving discomfort of eyes comprises a lens carrier and two side refracting prismatic lenses respectively installed on two sides of the lens carrier, the thickness of the two side refracting prismatic lenses is gradually increased from the far end to the inward approaching direction, and the prism degree of the two side refracting prismatic lenses is + 0.3 refraction degree < + 0.3 refraction degree < + 0.3 refraction degree < + 0.3 refraction degree < + 0.3 refraction degree < + 0.3 refraction degree < + 0.3 refraction degree < + 0.3 refraction degree < + 0.3 refraction degree < + 0.3 refraction degree < + 0.3 refraction degree < + 0.3 refraction degree < + 0.3 refraction degree. DIOPTER) is from + 3 fold brightness to + 3 fold brightness. Due to the arrangement of the refracting prismatic lenses on the two sides, incident light of an image is deflected when passing through the refracting prismatic lenses on the two sides, so that the depth of field of an eye image is changed. Therefore, the user can watch the image in a way of relaxing the ciliary muscle and extraocular muscle, and the fatigue discomfort caused by using the eyes for a long time is relieved.

Description

Technical Field

[0001] The invention relates to the technical field of optical lenses, in particular to a lens for alleviating eye discomfort. Background Art

[0002] 3D display technology has developed rapidly in recent years; humans have continuously created different 3D display technologies. However, no matter how the technical theories of stereoscopic display and automatic stereoscopic display are used, people sometimes experience symptoms such as discomfort, vomiting, dizziness and visual fatigue when watching 3D videos.

[0003] When a person's eyes view objects at different distances, the ciliary muscles will automatically adjust the curvature of the lens, causing the eyeball to produce three linkage theories, namely, miosis, convergence, and accommodation, thereby adjusting the viewing angle and focal length to make the objects seen by the eyes clear. The sense of distance such as far, near, deep, and shallow produced by 3D stereoscopic images causes the eyes to continuously adjust through the eye muscles when viewing 3D stereoscopic images through the above-mentioned 3D glasses in order to obtain clear images. Then, the continuous physiological adjustment mechanism will invisibly put a burden on the eyes, which will cause users to feel nausea, dizziness, visual fatigue, and other discomforts after watching 3D stereoscopic images for a long time.

[0004] When human eyes watch images at a fixed distance for a long time, it is easy for the ciliary muscles to maintain a fixed tense state for a long time. At this time, the extraocular muscles continue to work and adjust. Due to the physiological mechanism of the three-link movement of the eye muscles, it will cause great eye fatigue.

For technicians in the field of this case, they can understand the meaning of the above terms in various embodiments and even in this case with common knowledge or experience.

[0022] Please also see Figure 1 and Figure 3 The first embodiment of the lens for alleviating eye discomfort provided by the invention mainly includes: a lens carrier 10, the lens carrier 10 includes a nose bridge portion 11 and lens mounting portions 12 respectively arranged on two sides of the nose bridge portion 11, and the lens carrier 10 is worn on a user's eyes 50 through the nose bridge portion 11; and two side refractive prism sheets 20 respectively installed in the two side lens mounting portions 12, the thickness of the two side refractive prism sheets 20 gradually increases from one end 13 away from the nose bridge portion 11 to the direction close to the nose bridge portion 11, and the prism power of the two side refractive prism sheets 20 is +0.3 fold brightness (△; DIOPTER) ~ +3 fold brightness.

[0023] Due to the arrangement of the two-sided refractive prism sheet 20, the incident light of an image is deflected when passing through the two-sided refractive prism sheet 20, thereby changing the depth of field of the eye image, thereby allowing the user's ciliary muscles and extrinsic eyeball muscles to relax while viewing the image, thereby reducing the eye fatigue caused by long-term eye use.

[0024] In the first embodiment of the present invention, the lens carrier 10 further includes a tripod portion 14 respectively disposed on two sides of the nose bridge portion 11, and the two tripod portions 14 are worn on the ears of the user.

[0025] In the first embodiment of the present invention, the two side lens mounting parts 12 are substantially the same as the frames of traditional glasses, and are a closed frame structure for enclosing and mounting the two side refractive prism lenses 20 at a set position.

[0026] Please also see Figure 2 and Figure 3The second embodiment of the lens for alleviating eye discomfort provided by the present invention mainly comprises: a lens carrier 30, the lens carrier 30 comprises a nose bridge portion 31 and lens mounting portions 32 respectively arranged on two sides of the nose bridge portion 31, and the lens carrier 30 is worn on a user's eyes 50 through the nose bridge portion 31; and two side refractive prism sheets 20 respectively installed in the two side lens mounting portions 32, the thickness of the two side refractive prism sheets 20 gradually increases from one end 33 away from the nose bridge portion 31 to the direction close to the nose bridge portion 31, and the prism power of the two side refractive prism sheets 20 is +0.3 fold brightness (△; DIOPTER) ~ +3 fold brightness.

[0027] In the second embodiment of the present invention, the two side lens mounting portions 32 are substantially a clamping assembly for clamping and mounting the two side refractive prism lenses 20 .

[0028] In the lens for alleviating eye discomfort as described above, the two-side refractive prism lens 20 is a positive spherical diopter (DS) lens.

[0029] In the lens for alleviating eye discomfort as described above, the two-side refractive prism lens 20 is a negative spherical refractive power lens.

[0030] The lens for alleviating eye discomfort as described above, wherein the two-side refractive prism lens 20 is a progressive multifocal lens integrated with positive and negative spherical refractive power lenses.

[0031] In the lens for alleviating eye discomfort as described above, the two-side refractive prism lens 20 is made of one of lenses with different thicknesses, diffractive optical components, holographic optical components, and lenses with different refractive indices.

[0032] To compare the differences between the conventional and this creation, please refer to Figure 4 , with +1.0 fold brightness as an example. Adding two-sided refractive prism sheets 20 to both eyes for optical simulation, the binocular pupil distance is 65mm, and the actual imaging position is 489.626mm (A). The imaging position without wearing the two-sided refractive prism sheets 20 is 412.045mm (B). It can be explained from the results that after adding the two-sided refractive prism sheets 20, the depth of field of the image in the eye is changed. Because when watching the image at the fixed distance for a long time, it is easy to cause the ciliary muscle to maintain a fixed tight state for a long time. At this time, the extraocular muscles continue to work and adjust. Due to the physiological mechanism of the three-linked eyeball muscles, it will cause a lot of eye fatigue. Therefore, by changing the depth of field of the image in the eye, the user's ciliary muscle (ciliary muscle) and extraocular muscle (extrinsic eyeball muscles) are allowed to relax to watch the image, thereby reducing the fatigue and discomfort of the eyes caused by long-term use of the eyes.

Therefore, the case is not limited to the specific embodiments disclosed in the specification, and all modifications made according to the spirit and technical scope of the case should be covered and protected by the text content defined in the scope of the patent application.

[0036] Therefore, this invention has excellent progress and practicality among similar products. At the same time, after searching domestic and foreign technical data and literature on this type of structure, it is indeed found that there is no identical or similar structure existing before the application of this case. Therefore, this case should have met the patent requirements of "novelty", "suitability for industrial applicability" and "progressiveness", and the application is filed in accordance with the law.
