Ophthalmic lenses to prevent and slow the progression of myopia

Abstract

The invention relates to a spectacle lens for preventing and slowing down the development of myopia, which has the function of inhibiting the degree of myopia from further deepening under the premise of ensuring the visibility of the myopia wearer and correcting ametropia. The lens adds a surface disturbance of a weighting function to the spherical or aspheric base curve of traditional optical glasses. When looking at distant objects, since the weight of the weighting function in the hyperopia center area is low or even zero, the visual quality of myopia patients wearing this glasses when seeing far away through the optical center area is the same or similar to that of traditional optical glasses, and the glare at night Visual disturbances such as stray light are less severe than contact lenses designed to delay the progression of myopia. When looking at nearby objects, since the weight of the weighting function in the peripheral myopia ring area is relatively large or even equal to one, the periodic function will greatly disturb the retinal image points, so that the wearer can extend the retina backward under the premise of normal reading. The trend slows down or stagnates, achieving the effect of delaying the deepening of myopia.

Description

Technical field [0001] The present invention relates to an eye lens in an optical field, and more particularly to an ophthalmic glasses that prevent and slow myopia development. Background technique [0002] With the development of the spiritual civilization of material civilization, people use their eyes to read the time in recent years. Myopia has a high incidence rate in multiple regions around the world. [0003] Optical Correction Myopia The focal focusing on the retina is focused by changing the curvature of the lens to form a clear image on the retina. figure 1 It is a schematic diagram of a myopia patient to refract parallel light to focus in front of the retina, and 1 in the figure clearly indicates that myopic eye patients do not match the length of the eyeball in the distant object due to mismatches. The focus of eye optics 2 is in front of the retina. like figure 2 It is a schematic diagram of refractiveness in patients with traditional lens correction myopia patients...
