Abstract: A visual stimulus for a set of contrast cards is provided which comprises a hollow outer circle, opposing and identical first and second arc segment within the outer circle which are symmetrical about the vertical diameter of the outer circle, a first filled-in circle and a second filled-in circle being identical in diameter to the first filled-in circle, each residing on opposite ends of the horizontal diameter of the outer circle and each being equidistant from the center of the outer circle, a filled-in center element having a rotational center on the center of the outer circle, the center element being symmetrical about both the horizontal and vertical diameter of the outer circle.

Abstract: A myopia-inhibiting treatment device produces a therapeutic light that includes components of different wavelengths in a ratio of luminosities that creates a predetermined L-cone to S-cone excitation profile that slows ocular growth, thereby mitigating development of myopia. The components comprise blue light, green light, and red light. Therapeutic light may cause an L-cone to S-cone excitation ratio in a range between 1.38 and 0.05. In some implementations the therapeutic light causes a L-cone to S-cone excitation ratio of 0.74. In some implementations the luminosity of the combined light components is greater than 700 lux.

Abstract: A method and apparatus for reducing or preventing myopia is presented. In one mode, a display includes a front surface and a region is provided along at least one area of the front surface. The region provides temporal stimulation to a user viewing the display, which results in the prevention or reduction of myopia in a person viewing the display without the need for accurate accommodation or binocular fixation. In a second mode, a stand-alone device provides temporal stimulation to a user viewing the display, which results in the prevention or reduction of myopia in a person viewing the display. In a third mode, the temporal stimulation is projected into the viewer's field of view, which results in the prevention or reduction of myopia in a person viewing the projection.
Abstract: A method for at least one of preventing myopia and retarding the progression of myopia is provided. The method includes measuring optical aberrations in a human eye (42, 43, 44) and correcting the optical aberrations (46). Measuring optical aberrations (42, 43, 44) may include measuring wavefront aberrations (45) of parallel light rays entering the eye.
