Abstract

The invention discloses eye protecting glasses used during the process of using a computer. The structure of the eye protecting glasses is similar with that of common glasses, and is composed of a frame and lens. The principle and technology of the provided glasses are more dedicated. After people use computers, the eyes will feel swelling pain, and shortsightedness can be triggered easily. On the basis of optical principle of lens, the sight distance is effectively adjusted to match the sight distance and the eye using distance, and thus the eyes can be effectively protected under the situation that normal using of computer is not influenced.

Description

A kind of use computer time wear protect glasses

Technical field

The present invention is a kind of glasses worn when using computer, and when it can effectively alleviate use computer, eye pressure is formed with myopia.

Background technology

At present, computer has been enter into huge numbers of families, touch society's various aspects especially, using computer has been the basis of modern civilization, thus many families be all adolescents with learning life be equipped with computer, and on the other hand due to the needs of the amusement and recreation etc. that work, utilization computer becomes a part important in modern society's life especially, but consequently also bringing some disadvantages, such as myopia is formed, causes eye distending pain etc., especially for the teenager friend being in growth promoter.

Summary of the invention

Eye distending pain in order to cause when overcoming and use computer is formed with myopia, the invention provides a kind of wearing spectacles, it is similar with common spectacles, it is made up of with eyeglass mirror holder, but its principle and technology require the most single-minded, eye rock deformation pressure when these glasses can effectively alleviate use computer, makes utilization computer learning work amusement and recreation etc. the lightest.

The present invention solves the know-why that its technical problem used:

According to convex lens imaging principle: 1/u+1/v=1/f, when requiring that object distance (u) shortens, when image distance (v) is constant, only change focal length (f), and focal length (f) shortens, it is necessary to more convex lens could imaging.And the lenticular optical effect of our eye is just as convex lens, and can regulate well and regard Jiao, it cans be compared to image distance (v) to amphiblestroid distance, so our eye regards burnt (f) size with what object far and near (u) was frequently changed it, regarding burnt shorter during close-ups, namely crystalline lens can become more convex.

When using computer, (this distance definition is U to the distance of our eye of screen distance, lower same) generally all within one meter, compare and see the nearly many of TV, so eye is under the effect of natural mechanism, and crystalline lens compared with normal situation can become more convex, and keeps such state the most for a long time, eye muscle is the most tired, thus creates condition for eye distending pain and myopia formation etc..

In order to preferably use computer, reduce its adverse effect to eyes, allow it preferably for our study and work amusement and recreation etc. need service, this glasses (present invention) arise.For twenty-twenty vision, when using computer, our crystalline lens compared with normal situation can become more convex to adapt to such close-ups, and usually can keep this situation for a long time, if but the glasses (present invention) that we wear certain convexity in advance intercept sight line, sight line can be converged by its optical characteristics, and retracement line passes through crystalline lens again, at this moment when crystalline lens processes the sight line after converging, its convergence degree will reduce, namely will not be the most convex, so present invention just serves using computer age to shorten with object distance for eye crystalline lens and becomes convex optical effect, the effective eye crystalline lens that reduces becomes convex pressure, alleviate eye muscle nervous, effective less eye strain and myopia are formed；For another angle, the actual effect of the present invention is effectively to have adjusted the clear-vision distance of eyes, is allowed to reality eye distance from coincideing.In twenty-twenty vision, require to regard burnt (f) constant, image distance (v) is constant, to shorten depending on Jiao of glasses (present invention) immixture afterwards of additional certain convexity, so the object distance (u) of blur-free imaging can will become near, the distance namely can clearly observed will shorten, so the different object distance that can clearly observe of focal length according to the present invention is different under keeping eye normal condition, focal length is short, mixing regards burnt short, the object that can clearly observe is near, as long as so using the present invention to regulate clear-vision distance to U, this addresses the problem twenty-twenty vision and observe a difficult problem the most for a long time, thus more easily utilize computer learning work amusement and recreation to create condition for us, that is the effect of the present invention is the clear-vision distance of our observation regulated, it is allowed to use the distance of computer suitable with us.For different vision condition, the object distance (u) that when using computer, we observe is constant, constant at a distance of (v), become is to regard burnt (f), that just uses corresponding eyeglass (present invention) regulation clear-vision distance to U, such as, for height myope, select concave mirror to extend clear-vision distance and can conveniently use computer to U.In a word, when using computer, regulating our clear-vision distance by eyeglass (convex lens or concave mirror) is the original intention of the present invention to U, and its energy available energy alleviates eye pressure and myopia formation when using computer, makes us use computer more convenient.

The invention has the beneficial effects as follows: method is simple, easy to use, can effectively reduce the visual pressure of eye when using computer, make utilization computer learning work amusement and recreation etc. the lightest.

Accompanying drawing explanation

The present invention is further described below in conjunction with the accompanying drawings.

Fig. 1 is sketch of the present invention.

Fig. 2 is the optical imaging concept schematic diagram of twenty-twenty vision eye normal observation distance.

When Fig. 3 is to use computer, the optical imaging concept schematic diagram of twenty-twenty vision eye close-ups.

When Fig. 4 is to use computer, after using the present invention, the optical effect schematic diagram of twenty-twenty vision close-ups.

In figure: 1. sightingpiston, 2. object distance u, 3. image distance v, 4. regard burnt f, 5. observe object imaging on the retina, 6. eye, 7. eye crystalline lens, eyeglass the most of the present invention.

Detailed description of the invention

In fig. 2, in the case of twenty-twenty vision, when our eye (6) observes object, eye crystalline lens (7) optical effect principle cans be compared to convex lens, its image-forming principle meets: 1/u+1/v=1/f, u is to observe the object distance (2) away from eye, and v is image-forming range (3), and f regards burnt (4) for regarding Jiao or mixing.

As shown in Figure 3, in the case of twenty-twenty vision, when using computer, sightingpiston (1) than Fig. 2 becomes closer to, owing to v is constant, so the focal distance f of only our crystalline lens (7) can become shorter could blur-free imaging, the most as shown in Figure 3 crystalline lens (7) can become than in Fig. 2 more more convex.

Shown in Fig. 4, in the case of twenty-twenty vision, when using computer, in the case of identical with observation object (1) distance of Fig. 3, use the present invention (8), its action effect is that Fig. 4 crystalline lens (7) situation is identical with crystalline lens in Fig. 2 (7) situation, and imaging optical effect (5) is identical with Fig. 3.

For different vision condition, the eyeglass that can be selected for different size reaches above-mentioned similar optical effect.

Claims
