Abstract

The utility model relates to a multifunction enhanced eyesight glasses with bifocus, which is a pair of physical therapy glasses for medical application, comprising a glasses frame and porous opaque eyeglasses with different intervals. The utility model has the advantages of large visual field, imaging sharp when seeing near and far, no diplopia, and has an obvious vision-enhancing effect on various types of visual disturbances and the function of controlling pseudomyopia. In addition, the utility model can also relieve visual fatigue caused by watching television to take effect on vision protection. When used, the glasses are worn; when people are looking horizontally or looking at a far object with the utility model, the section whose intervals between the small holes on the upper eyeglass are comparatively sparse is in use; when people are reading, writing or looking at a near object, the section whose intervals between the small holes are comparatively dense is in use.

Description

Multifunction enhanced eyesight glasses with bifocus

The multi-functional glasses that increases of bifocal is a kind of medical physiotherapeutic glasses, more particularly is a kind of pinhole imaging system principle design of utilizing, and has the medical physiotherapeutic glasses that increase visual function.

The application of pinhole imaging system principle in field of ophthalmology is existing for many years.Aperture can reduce the spherical aberration of eyes, increases the depth of field, weakens light intensity, and therefore, it is more clear, true to nature to see through observed nature scenery of aperture or display image screen, and matching in color, and briliancy is suitable.Present existing aperture apparatus is because in the design, range of application is very narrow, or effect is undesirable.As: the visual field is too narrow, use is inconvenient, look look closely clearly far unclear; Not fogging or produce diplopia and look phenomenon more.

That the purpose of this utility model is to provide is a kind of wide-angle, that far and near distance is all suitable, imaging clearly, easy to use, the number of different types vision disorder all had to increase regards usefulness as, pseudo-myopia is had the medical physiotherapeutic glasses of preventive and therapeutic effect.In addition, the utility model can also alleviate the asthenopia of seeing that TV causes, plays the vision protection effect.

For achieving the above object, the utility model is made up of the opaque lens of porous (1) mirror holder (2) that pitch-row does not wait.It is characterized in that: lens is made by opaque materials such as plastics, organic glass, xylonite or metals, is covered with the aperture that diameter is 1.2-1.5mm on the eyeglass, and eyeglass top aperture pitch is 6-6.5mm, and eyeglass below aperture pitch is 3-3.5mm; Spectacle frame is made by plastics, organic glass or metal material.

Allow the patient that glasses are worn on the eye during use, look squarely or when seeing distant objects, be the position of 6-6.5mm with the top aperture pitch, reading and writing or when looking nearly thing is the position of 3-3.5mm with the below aperture pitch.

Advantage of the present utility model is:

1. the big visual field of wide-angle.

2. all clear and briliancy of far and near distance imaging is suitable.

3. do not produce diplopia or look phenomenon more.

4. obviously increase the UCVA of myopia, long sight, presbyopia and astigmatic eyes.

5. the mydriasis eye is had to increase and look and protective effect.

6. ophthalmology illness such as corneal inflammation, conjunctivitis and operation back eye have to increase and look and alleviate the irritation effect.

7. can weaken the briliancy of TV screen, increase the sharpness of tv screen image, thereby alleviate the visual fatigue of seeing that TV causes.

8. pseudo-myopia there are treatment and prevention effect.

Structure of the present utility model is provided by accompanying drawing, and wherein 1 is 1.2-1.5mm for being covered with diameter, and the upper aperture spacing is that 6-6.5mm below pitch of holes is the opaque lens of 3-3.5mm aperture; 2 is spectacle frame.

Specific embodiment of the utility model: the multi-functional glasses that increases is made up of lens and mirror holder, its eyeglass as shown in the figure, be covered with the aperture that diameter is 1.2-1.5mm on the opaque eyeglass, the upper aperture spacing is 6-6.5mm, eyeglass below pitch of holes is 3-3.5mm, and mirror holder is that plastics, organic glass or metal material are made.

Concrete using method when the utility model is used to prevent and treat pseudo-myopia:

Pseudo-myopia mostly is low degree short sightedness, can wear spectacles, replaces spectacles to look thing with the utility model and can get a distinct image equally.Simultaneously, wear the utility model every day and stare a distant place 2-3 time, each 10-20 minute, adjusting anxiety that can easing eyes, loose ciliary spasm, thus reach the purpose of preventing and treating pseudo-myopia.

Claims

1, the multi-functional glasses that increases of a kind of bifocal is made up of spectacle frame and eyeglass, it is characterized in that: eyeglass is that opaque thin plate is made, it is 1.2-1.5mm that the eyeglass top is covered with diameter, spacing is the aperture of 6-6.5mm, and it is 1.2-1.5mm that the eyeglass below is covered with diameter, and spacing is the aperture of 3-3.5mm.
