    Abstract: Pinhole glasses which can be used to assist people with low to moderate myopia, hyperopia, and astigmatism, are invented. The present invention can be used for glasses which function as progressive glasses, distance glasses, computer glasses, reading glasses, and when tinted, sunglasses. The present invention provides the best balance of visual acuity, brightness and visual field with emphasis on acuity, through the system of axes and the pinholes in multiple sizes along the axes which are clinically and empirically proven to be effective. Especially, the placement of pinholes along the axes has clinically and empirically been determined depending on the seriousness of the astigmatism of the users in correcting the astigmatic refractive errors. The size, number, spacing, pattern, and axes of the pinhole apertures have been optimized through optical theories and extensive clinical and empirical testing.
