Abstract
The utility model relates to a pair of diopter adjustable glasses. A glass frame is provided with a diopter-adjusting device and a pair of focusing lenses, the diopter-adjusting device can use a mechanical-pressure adjusting device or a piezoelectric ceramic plate, and the high polymer lenses can be made of CR-39 allyl group diol, carbonic acid ester, etc. Refracting liquid can use simple substance or mixed liquid which has the same refractive index as the lenses, and the magnetic crystal lenses can be made of transparent magnetic crystal materials, such as LDP, ADP, etc. The utility model has the advantages of simple structure and convenient operation, and the diopter can be used continuously.
Description
The utility model relates to a kind of glasses, particularly a kind ofly changes dioptric glasses.
Present employed Zoom glasses has two kinds, and a kind of is that the eyeglass of glasses is the aspheric surface shape, increases continuously diopter downwards from the central point of lens; Another kind is a Zoom glasses, inlays the different eyeglass of a fritter diopter at the local location of eyeglass.During use, need to change the visual angle, allow sight line pass through corresponding dioptric position, shortcoming is that bigger distortion is arranged when looking thing, the discontinuous variation of diopter.
The purpose of this utility model provides a kind ofly can adjust dioptric Zoom glasses continuously.
The purpose of this utility model is achieved in that this focus-adjustable glasses comprises a spectacle frame, be characterized on spectacle frame, having installed a diopter regulator and a focusing eyeglass, the focusing eyeglass has two kinds, a kind of is to make preceding eyeglass, back eyeglass by high molecular polymer, has been full of simple substance or the mixing material identical with the eyeglass index of refraction in the cavity of preceding eyeglass and back eyeglass composition; Another kind of eyeglass can be made with transparent magnetic crystal.
The utlity model has simple in structure, easy to use, the advantage that diopter can be regulated continuously.
The utility model will be further described below in conjunction with accompanying drawing.
Fig. 1 is the structural representation of high molecular polymer eyeglass focusing lens.
Fig. 2 is the left view of Fig. 1.
Fig. 3 is the structural representation of mechanical pressure adjuster.
Fig. 4 is the structural representation of magnetic crystal eyeglass focusing lens.
Fig. 5 is the left view of Fig. 4.
This focus-adjustable glasses comprises spectacle frame 1, mechanical pressure adjuster 2, high molecular polymer eyeglass 3, refractive power liquid 4, piezoelectric ceramic piece 5, magnetic crystal eyeglass 6, in the chamber of forming by high molecular polymer eyeglass 3 and rubber ring 8, fill with refractive power liquid 4, eyeglass 3 can be by the CR-39 allyl diglycol carbonates, or polymethylmethacrylate or heavy plumbous optical glass, or lead molybdate, or high molecular polymer such as zinc paste is made, refractive power liquid 4 can be selected simple substance identical with eyeglass 3 indexs of refraction or mixing material refractive power liquid for use, the slide block 7 of mechanically moving pressure regulator 2 to the left or to the right, the focal length of eyeglass 3 can recur variation, reaches the purpose of focusing.For the focus-adjustable glasses of selecting magnetic crystal eyeglass 6 for use, can change the electric field or the magnetic field of piezoelectric ceramic piece 5 by switch 9, reach the diopter of adjusting magnetic crystal eyeglass 6, magnetic crystal eyeglass 6 can adopt KDP or ADP or silver-colored sour lithium or transparent magnetic crystal such as bismuth silicate or sour bismuth.
Claims (5)
1, a kind of focus-adjustable glasses, it comprises spectacle frame, it is characterized in that having installed on the spectacle frame diopter regulator and one pair of focusing eyeglass.
2, focus-adjustable glasses according to claim 1, it is characterized in that focusing eyeglass by CR-39 allyl diglycol, carbonic ester or or polymethylmethacrylate or heavy plumbous optical glass, or lead molybdate, or high molecular polymer such as zinc paste is made.
