Description

可调式护视镜
本实用新型涉及眼镜,特别是用于防治近视眼的可调式护视镜。
护视镜是一种可有效防治近视眼的眼镜,近视患者可利用上端的近视镜片看清黑板等远处物体,利用下部的雾视镜片看书学习。这样近视患者在近距离读写时,雾视镜片能使人眼的睫状肌反向调节处于休息调整状态,这样使近视眼患者,尤其是学生患者读写时眼肌不再疲劳,以达到防治近视眼的效果。护视镜要求雾视镜片(凸透镜片)的光心对准人眼的瞳孔,这样才能达到防治目的。近视眼发病初期集中在中小学生中,在初次配戴眼镜时可选择宽窄适宜的眼镜架,使雾视镜片的光心恰好对准瞳孔。但青少年处于生长发育的旺盛期,随着眼距变宽,由于不可能经常更换镜架,使护视镜起不到应有作用,甚至带来危害。
本实用新型的目的在于提供一种镜架可调,可发挥护视镜片作用的可调式护视镜。
本实用新型的技术解决方案为:可调式护视镜,包括眼镜架、眼镜片,近视镜片上带有凹槽,雾视镜片带有与近视镜片上的凹槽相配合的凸起,两者镶嵌粘接;眼镜架中部带有宽窄调节旋钮。
按照上述技术方案,随着青少年的生长发育带来的眼距变宽,可拧动宽窄调节旋钮随时调节眼镜片间距,保持雾视镜片的光心对准眼瞳孔,使护视镜发挥防治近视眼的作用。同时拧动镜腿长短调节旋钮,可改变镜腿长度,使配戴更合理更舒适。
附图1为本实用新型结构示意图;
附图2为本实用新型护视镜片分解示意图;
附图3为本实用新型镜腿可调式结构示意图。
结合附图,对本实用新型的实施例作描述。
可调式护视镜,包括眼镜架、眼镜片,近视镜片2上带有凹槽,雾视镜片3带有与近视镜片2上的凹槽相配合的凸起,两者镶嵌粘接;眼镜架1中部带有宽窄调节旋钮4。在眼镜架1上带有镜腿长短调节旋钮7。眼镜架1上带有固定杆5。雾视镜片3固定在近视镜片2的中下部,雾视镜片3的球弧形凸起镶嵌在近视镜片2球弧形凹槽内,镜片上带有镀膜6。
