[0022] The present invention will be further described below in conjunction with the accompanying drawings of the description.
[0023] Such as Figure 1-4 As shown in , a novel rigid gas-permeable contact lens includes a peripheral arc 2 of the lens 1, and is characterized in that: the inner edge of the peripheral arc 2 of the novel rigid contact lens is provided with two symmetrical stabilizing wing areas 3 or three stabilizing wing areas 3; the distance D between the inner and outer ends of the stabilizing wing area 3 is 0.2-7mm; the concave inner arc surface of the stabilizing wing is conical arc, spherical arc or aspheric arc.
[0024] The three stabilizing wing areas 3 are equidistantly or unequally distributed along the inner edge of the peripheral arc area 2; each of the stabilizing wing areas 3 is 1 / 6-1 / 3 of the inner edge; the three stabilizing wing areas The shape and size of the zones can vary.
[0025] The inner arc surface 4 of the stabilizing wing is a conical...
