  • Patent number: 11284794
    Abstract: In certain embodiments, a system for tracking movement of an eye comprises a camera system, a computer system, and an output device. The camera system generates images of the eye. The computer system stores the images and at least one of the images as a reference image. The computer system also tracks movement of the eye within a tracking range by comparing a current image with the reference image, and by determining a movement of the eye from the comparison of the current image and the reference image. The tracking range has one or more alert points. The computer system also determines an orientation of the eye relative to at least one alert point of the tracking range. The output device outputs a range indicator that indicates the orientation of the eye relative to the at least one alert point of the tracking range.

  • Patent number: 11243413
    Abstract: 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.
