Pulse in a food processor until very finely chopped. Combine milk, flour, salt, pepper and nutmeg in a large saucepan. Cook over medium heat, whisking, until thickened, 2 to 4 minutes. Remove from the heat and stir in half a cup of cheddar, cottage cheese and the spinach.
An aspheric lens or asphere is a lens whose surface profiles are not portions of a sphere or cylinder. In photography, a lens assembly that includes an aspheric element is often called an aspherical lens. The asphere's more complex surface profile can reduce or eliminate spherical aberration and also reduce other optical aberrations such as astigmatism, compared to a simple lens.
Aspheric IOLs: from Theory to Practice If implanted properly, aspheric lenses may provide improved visual function over traditional spherical IOLs. SEVERAL ASPHERIC INTRAOCULAR LENSESâlenses in which the front surface is not curved as part of a sphere but is relatively flatter in the peripheryâhave hit the market and reportedly provide superior contrast sensitivity over the more traditional spherical IOLs.
