Web1 Aug 2024 · Flatter curves are created which gradually change over the lens surface. This can be done on one side of the lens (Aspheric), or both sides of the lens (Double Aspheric) - the latter double option being the thinnest and lightest. This is a technology that can be combined with a high index lens option to get the sleekest result. Web8. A lens marketed as "aspherical" will usually have only one surface (one side of one piece of glass) aspheric, and all the other surfaces will be spherical (or flat). So the vast majority of glass in any lens, even those lenses marketed as aspherical, is spherical anyway. An aspheric surface can help correct for spherical aberration, which ...
