Device for asymmetrical refractive optical correction in the peripheral retina for controlling the progression of myopia
Optical device ( 1 ) for modifying the optics of the eye in its peripheral retina as prophylaxis of the progression of myopia, that it consists in a lens in which its inferior nasal quadrant ( 2 ) modifies the strength in a progressive and controlled manner from the center to the outer zone of the lens. The rest of the quadrants ( 3 ) of device ( 1 ) have a configuration of a graduated crystal or flat crystal, depending, respectively, on whether the user has some visual defect that requires optical correction or lacks said defect. The lens can be either an optical lens, a contact lens or electro-optical systems.
