Abstract
titled "Diffusion Optics Technology (DOT): A Myopia Control Spectacle Lens Based on Contrast Theory."Based on the finding that mutations that cause the longer wavelength cones to randomly be either normal or of impaired efficiency are associated with high myopia, they proposed that this was because the heterogeneous cone mosaic signaled a spuriously high contrast.From this insight, they developed a novel myopia control lens that reduces image contrast Figure.(A) Image of black-and-white grayscale trees as recorded by a video camera.The horizontal bar represents approximately 1 degree of visual angle.(B) Same as panel A, but with the peripheral optics of a MyoCare 0-diopter (D) lens placed in front of the camera lens.(C) Intensity of a horizontal row of pixels passing through the image center taken from the image without (top subpanel) and with (bottom subpanel) an added MyoCare 0-D lens.(D) The radially averaged amplitude spectrum of the Fourier transforms of the grayscale images, with and without the added MyoCare 0-D lens.
