    • A rigid corneal contact lens comprises a front-surface optical zone and a back-surface optical zone: the front-surface optical zone comprises a front-surface central zone (1) and a defocusing zone (2) at the periphery of the front-surface central zone (1); the front-surface central zone (1) is spherical; the defocusing zone (2) has a radius of curvature decreasing from the outside of the front-surface central zone (1) continuously and a minimum radius of curvature which ranges from 95% to 50% of the radius of curvature of the front-surface central zone (1). Because of the structure of a human eye, the phenomenon of peripheral hyperopic defocus exist in human eyes, that is, central image points for an image are projected on macula foveal of retina and peripheral image points are projected behind retina. As shown in experimental evidences, peripheral hyperopic defocus is the main cause of myopia development which can be moderated by restraining peripheral hyperopic defocus. In this present disclosure, a rigid corneal contact lens featuring stronger refractive power at the lens's periphery than at the lens's central area contributes to moderating peripheral hyperopic defocus for myopia control.

    • An electrical connector comprises an insulating housing having a main body and a mating portion extending forwardly from a front surface of the main body. The main body defines a mounting surface perpendicular to the front surface and a top surface opposite to the mounting surface. The main body defines a pair of receiving cavities located at two ends thereof, a pair of nuts are received in the receiving cavities respectively. Each nut comprises a board-shaped base portion, a threaded portion stamped from the base portion and a threaded hole therethrough. A plurality of terminals are assembled to the insulating housing. A pair of bolt-inserting apertures penetrate from the top surface to the mounting surface through the threaded holes of nuts respectively. The base portion defines a retention portion interfering with internal walls of the receiving cavity.

    • An electrical connector has an insulative housing defining a mating portion defining a front surface and a back surface opposite to the front surface. A plurality of contacts is secured in the housing and define soldering tails. The contacts include a group of first contacts. A spacer is assembled to position the soldering tails and comprises first mounting holes to be inserted with the soldering tails of the first contacts. The first mounting holes of the spacer are lined in at least two rows and each row has a same number of the first mounting holes to a total number of the first contacts.
