    • A screw includes a head portion (1) with a driving socket formed thereon. The driving socket has a bottom portion, a square recess (44) and four fan-shaped recesses (40,41,42,43). The square recess (44) is defined by four vertical walls (440,441,442,443). The four substantially vertical walls (440,441,442,443) taper inwards the bottom portion (46) of the socket and are separated to one other by four corner gaps respectively. The four fan-shaped recesses (40,41,42,43) extend respectively and outwardly from each of the corner gaps and are integral with the square recess (44). Each fan-shaped recess (40,41,42,43) is defined by two outward walls (47,48) and an outer wall (49), and the two outward wall (47,48) and the outer wall (49) taper toward the bottom portion (46) of the socket.

    • A vision training device includes a fixed frame positionable in front of a wearer's face. The fixed frame defines two windows corresponding in position to the eyes of the wearer, through which light passes. An optic system includes a prism lens, which may have fixed power or variable power by changing shapes thereof. The prism lens is mounted to the fixed frame and is movable between first and second positions, wherein in the first position, light is allowed to pass in a first state with which the eyes are adducted, and in the second position, light is allowed to pass in a second state with which the eyes are abducted. A transmission system is coupled to and selectively drives the prism lens between the first and second positions. Thus, by repeatedly and cyclically moving the prism lens between the first and second positions, the eyes are forced to change between adduction and abduction thereby realizing training of vision.
    • 视力训练装置包括可定位在佩戴者面部前方的固定框架。 固定框架限定了与佩戴者眼睛相对应的两个窗口,光线通过该窗口。 光学系统包括棱镜透镜,棱镜透镜可以通过改变其形状而具有固定的功率或可变的功率。 棱镜镜片安装在固定框架上,并可在第一和第二位置之间移动,其中在第一位置,允许光线在眼睛内收的第一状态下通过,并且在第二位置,允许光线 通过眼睛被绑架的第二种状态。 传输系统耦合到第一位置和第二位置之间并选择性地驱动棱镜透镜。 因此,通过在第一和第二位置之间反复循环移动棱镜,眼睛被迫在内转和外展之间转换,从而实现视力的训练。
