Detailed Description
The invention is further described in detail with reference to the following specific examples and the accompanying drawings. The procedures, conditions, experimental methods and the like for carrying out the present invention are general knowledge and common general knowledge in the art except for the contents specifically mentioned below, and the present invention is not particularly limited.
In fig. 1-4 c, 1-the frame; 11-front mirror frame; 12-rear mirror frame; 13-an adjustment port; 14-a support point; 2-a lens; 21-a front lens; 211-upper serrations; 22-a rear lens; 221-upper serration; 3-an adjusting mechanism; 31-knob portion; a 32-gear portion; 4-screws.
The glasses with adjustable lens power provided by the embodiment comprise: the spectacle frame is provided with an adjusting mechanism; the lens is arranged in the frame and can move in the frame; the lens includes: a front lens and a rear lens; the front lens and the rear lens are Alvarez curved lenses, and the transverse relative positions of the front lens and the rear lens are changed through the adjusting mechanism, so that the relative thickness of the lenses is changed, and the adjustment of the lens degrees is realized.
In this embodiment, as shown in fig. 1, the lens frame includes: a front frame and a rear frame; the front mirror frame and the rear mirror frame are fixed with each other through screws. Be equipped with a plurality of strong points in preceding picture frame, its contact with the last downside of preceding lens and back lens simultaneously for support lens avoids the lens direct and picture frame friction to lead to the resistance too big, makes preceding lens and back lens can transversely drag on the strong point in preceding picture frame. The size of the lens is slightly larger than the inner rings of the front and the rear spectacle frames, so that the lens cannot fall out of the spectacle frames.
In this embodiment, be provided with the regulation mouth on the picture frame, adjustment mechanism sets up in the picture frame, and the user can conveniently use the finger to rotate adjustment mechanism through adjusting the mouth.
In this embodiment, picture frame top both ends all are provided with the regulation mouth.
