It is layer structure to state eyeglass, includes substrate layer, reflecting layer, stiffened protective layer successively from eyeglass outer surface to inner surface；Described
Substrate layer is formed by substrate positive camber and substrate negative camber；The wherein described substrate outcurve or substrate negative camber are aspherical；
The aspherical mean power variable quantity regarded in the range of burnt central area is no more than 0.06D, the power variation of buffering area
Amount is no more than 0.35D and is fairing change.
More preferably technical solution is on the basis of above-mentioned technical proposal：State aspherical geometric center diameter 30mm regional extents
Interior mean power variable quantity is no more than 0.06D.What so design can make to play main correcting regards burnt central area
Focal power change is gentler, further mitigates spinning sensation when wearing.
Due to the use of above-mentioned technical proposal, its remarkable advantage is as follows compared with prior art for the utility model:One will be used
Piece eyeglass is the dual-use function that near-sighted glasses and sunglasses can be achieved, and due to the addition in photochromic reflecting layer so that eyeglass
Light penetration is reduced in the sun, and by regarding averagely bending in the range of burnt central area to the aspherical of substrate negative camber
Light varience amount is no more than 0.06D, not super more 0.35D of buffering area power variation amount and be the design of fairing change, you can
The thickness of eyeglass to be thinned significantly, so as to mitigate weight, and lead to and focal power fairing change design is avoided because of focal power saltus step
The dizzy problem of wearing being likely to occur.
