WebA flat lens is a lens whose flat shape allows it to provide distortion-free imaging, potentially with arbitrarily-large apertures. The term is also used to refer to other lenses that provide a negative index of refraction. Flat lenses require a refractive index close to −1 over a broad angular range. In recent years, flat lenses based on metasurfaces were also demonstrated. WebTwo common refractive errors of the eye are myopia and hyperopia. Myopia, which is also known as nearsightedness, occurs when the eye can focus on nearby objects, but not on far away ones.
