Background

Myopia refers to the condition of relaxed accommodation in which parallel rays of light are focused in front of the retina after refraction by the dioptric system of the eye. Ancient doctors have recognized this disease early, which is called eye failure of hypermetropia and near-shy distant disease.

Presbyopia refers to the condition of gradual reading or working difficulties in close quarters by elderly people. This is a phenomenon of aging of human body functions. Most people can quietly feel 'presbyopia' in the eyes of about 40-45 years old, and firstly feel that fine writing is fuzzy, and books and newspapers need to be taken far to see the writing on the books and the newspapers.

Some myopia and presbyopic patients need respectively to wear a pair of glasses usually, it is inconvenient to switch to take, the dual-purpose glasses of myopia glasses and presbyopic glasses that are used for wearing have not appeared in the prior art, the leading cause is that, the myopia is worn and the glasses shape that presbyopic wore is inconsistent, consequently be difficult to integrate together, do not appear convenient operation's lens switching structure in addition on traditional eyes picture frame, consequently based on above difficult point, the dual-purpose glasses of myopia and presbyopic does not appear in the existing market.

Detailed Description

The invention will be further described with reference to the following figures 1-4 and examples:

aiming at the problem that a lens switching structure convenient to operate does not exist on an eye frame in the prior art, the utility model relates to a pair of glasses for myopia and presbyopia, as shown in figure 1, the glasses comprise a main frame 1, an auxiliary frame 2, a switch 3, legs 4 and lenses, wherein the legs 4 are connected with two sides of the main frame 1, the lenses are arranged in the main frame 1 and the auxiliary frame 2, the auxiliary frame 2 is rotatably connected with the bottom of the main frame 1, an inner cavity 5 is arranged in the main frame 1, a first blind hole 5-1 is horizontally opened towards one side of the auxiliary frame 2, the switch 3 is arranged in the inner cavity 5, a convex magnetic block 6 is correspondingly arranged on the side of the auxiliary frame 2 towards the main frame 1, the convex magnetic block 6 can be inserted into the first blind hole 5-1 to contact with the switch 3 after the main frame 1 and the auxiliary frame 2 are folded, the material of the switch 3 can be set into a metal material convenient for the convex magnetic block 6 to adsorb, for example, the inner cavity 5 is provided with a second blind hole 5-2 at the top of the main mirror frame 1, and the top of the change-over switch 3 is exposed outside the second blind hole 5-2 to form a button 3-1.

In this embodiment: considering that the whole material of the change-over switch is metal, which increases the weight of the glasses frame and causes discomfort in wearing, an iron sheet 7 may be disposed at a position where the change-over switch 3 is in contact with the surface of the convex magnetic block 6, the specific structure is as shown in fig. 2, the thickness of the change-over switch 3 gradually increases along the contact position toward the second blind hole 5-2, and an inclined plane a is formed above the contact position, the inclined plane a is used for abutting against the convex magnetic block 6 when the change-over switch 3 is pressed, so as to gradually enlarge the distance between the iron sheet 7 and the change-over switch 3, the inner cavity 5 is further provided with a sliding groove 5-3, after the button 3-1 is pressed, the change-over switch 3 moves downwards along the sliding groove 5-3, a spring 8 is disposed between the bottom of the change-over switch 3 and the sliding groove 5-3, and the cooperation of, the inclination angle of the inclined surface a is enough to enable the magnetic convex block 6 to be separated from the iron sheet 7 and finally fall off in the process that the change-over switch 3 moves downwards along the sliding chute 5-3.

In another embodiment: in order to solve the problem of folding accomodating, still be equipped with connecting piece 9 between main picture frame 1 and the mirror foot 4, as shown in fig. 1, main picture frame 1 rotates with connecting piece 9 to be connected, mirror foot 4 rotates with connecting piece 9 to be connected, and direction of rotation mutually perpendicular, folding back schematic diagram is shown in fig. 3, this kind of different side folding mode lies in for the folding benefit of traditional glasses homonymy, and the mirror foot after folding lies in the both sides of lens to can play certain guard action to the lens, especially hand can prevent that the fingerprint from polluting the lens.

In another embodiment: consider traditional myopia and the difficult dual-purpose formula that designs into an organic whole of presbyopic glasses lens structure, the utility model discloses improve the lens, it is concrete that to install the lens in main picture frame 1 and establish to concave lens 10, install the lens in vice picture frame 2 and be convex lens 11, and this concave lens 10 laminates with convex lens 11's contact surface each other, as shown in fig. 4, can form convex lens when main picture frame 1 and the laminating of vice mirror frame 2 are in the same place, use as the presbyopic glasses, after vice mirror frame 2 overturns, the concave lens 10 of main mirror frame 1 uses as the myopia glasses to the painful point of traditional dual-purpose glasses has been solved.

In another embodiment: still be equipped with support and support leaf on the dual-purpose glasses of myopia presbyopia, wherein support leaf and nose direct contact, the support is used for connecting support leaf and primary mirror frame: the nose pad and the support are movably connected or the support, the nose pad and the main lens frame are of an integrated fixed structure, the design aims to consider that customers with different wearing habits have different requirements on the movable nose pad and the fixed nose pad, and it needs to be explained that the fixed nose pad and the movable nose pad are only conventional nose pad structures in the prior art, so that the details are not repeated.

In another embodiment: considering that the overall weight is increased by adding the change-over switch in the scheme, the inner part of the glasses leg 4 is designed to be hollow and reduce the weight, so that the overall weight is equal to the weight of the existing glasses frame.

The embodiment of the present invention discloses a preferred embodiment, but not limited thereto, and those skilled in the art can easily understand the spirit of the present invention according to the above embodiment, and make different extensions and changes, but do not depart from the spirit of the present invention, all of which are within the protection scope of the present invention.
