| titleOfInvention | A kind of frame mirror eyeglass of myopia correction |
| abstract | The present invention relates to a kind of frame mirror eyeglasses of myopia correction, frame mirror eyeglass is selenodont negative lens, including convex lens surface and eyeglass concave surface, the middle section of convex lens surface is convex surface optics area, the middle section of eyeglass concave surface is concave surface optics area, convex surface optics area and concave surface optics area be it is spherical, the center of convex lens surface and eyeglass concave surface is spherical crown vertex, and the radius of curvature of convex lens surface is more than or equal to 30 millimeters and is less than or equal to 100 millimeters.The optics principal point of frame mirror eyeglass is mobile to opthalmic optics' principal point direction, allows the optics principal point of frame mirror eyeglass to be overlapped with the optics principal point of human eye or Distance Shortened, reduces and distort, while reducing the contracting image effect of contracting picture frame mirror eyeglass. |
