Abstract
The utility model discloses myopia prevention glasses that essentially comprise a connecting section between two eyeglasses of the glasses and a control circuit, wherein, the edge at the lower part of the connecting section is corresponding to a physiological structure at the upper part of a nose while the width of the middle part is larger than the diameter of a 3V button cell. The connecting section is provided with a cavity body for installing the button cell and an electrode of a direct-current power source of the control circuit is arranged at both sides corresponding to the button cell while the other electrode of the direct-current power source of the control circuit is arranged at the lower part corresponding to the button cell; two sides of the cavity body are respectively provided with a sensor used for measuring distances and a vibrator; the control circuit comprises the sensor, an amplifying circuit, a comparator and the vibrator connected in sequence while the amplifying circuit, the comparator and the vibrator are connected with a direct-current power source provided by the button cell; an electric circuit part of the control circuit is plastically sealed in the connecting section. The myopia prevention glasses can automatically inform that a user is too close to a book in reading.
Description
(1) technical field
The utility model relates to a kind of glasses, specifically relates to a kind ofly can effectively prevent the anti-myopia glasses that the eyes number of degrees continue to increase the weight of.
(2) background technology
Eyes are under the state that does not use regulating action, and the dioptric system of parallel rays through having a look at forms focus before retina, are the aperture that disperses and blur then to retina, and this refractive status is called myopia.Wherein closely read a book etc., make eyes be in the excessive state of a kind of curvature always, of long duration, the eyes capacity of self-regulation descends, and has also just caused myopia.So bad reading custom is considered to the one of the main reasons of hypometropia, yet though as you know these, the custom of forming at ordinary times often is difficult to change, in reading always consciously or unconsciously return to original sitting posture and reading state.With advancing age, the rectification of custom is difficult all the more.For this, still there not be at present good way, main cause is that forming of being accustomed to of student taken time and efforts, unless there is the people to monitor him specially, pressure allows him correct, however this is unrealistic.
(3) summary of the invention
The utility model is read a book at present correction student and is accustomed to not having the deficiency of good method, provides a kind of and can inform automatically that reading is from the near excessively anti-myopia glasses of books.
The technical solution adopted in the utility model is:
The utility model anti-myopia glasses, comprise connecting portion and control circuit between glasses two eyeglasses, wherein the connecting portion lower edge is corresponding to nose top physiological structure, its middle part width is greater than 3V button cell diameter, this one is provided with the cavity of device button cell, be provided with the electrode of the direct supply of control circuit corresponding to the button cell both sides, be provided with another electrode of control circuit direct supply corresponding to the button cell bottom; Above-mentioned cavity both sides are provided for the sensor and the Vib. of measuring distance respectively; Control circuit then comprises above-mentioned sensor, amplifying circuit, comparer and the Vib. that connects successively, and back three links to each other with the direct supply that above-mentioned button cell is provided; The circuit part plastic packaging of above-mentioned control circuit is in described connecting portion.
The utility model anti-myopia glasses, its principle are the control circuit of plastic packaging in the glasses connecting portion, comprise being used to gather the sensor of eyes from the books range information, link to each other with amplifying circuit through comparer then.If hypotelorism, then comparer has surpassed the normal range that eyes allowed through the vibration of amplifying circuit control Vib. thereby warn user's books distance, can reach Real-time Alarm, thereby effectively prevent the excessive use eyes lack of standardization of user.The used device of the utility model all is a gadget, and directly plastic packaging does not influence the glasses outward appearance in connecting portion, and is easy to use.And used device power consumption is low, and what inconvenience button cell can not bring with for a long time.
