Abstract

On the one hand, the invention provided an intraocular lens (that is, the intraocular lens) with a There are front and back surfaces around the optical axis. At least one surface (ie the front surface) has an overlapping profile of the baseboard and the reinforced scaffold.Accessory can have at least two areas (that is, the inner area and the outer area). And one or more transitional areas are between the areas where the divergence of the light path intersects. The transition area (The optical path difference between the inner and outer radial edges of the Transition area) corresponds to the non-integer segment (ie 1/2) of the design wavelength (ie approximately 550 nm).

Claims (1)

1. an eyepiece that has a front and a back surface around the optical axis At least one of these surfaces has an overlapping profile. Of base frame and auxiliary frame Such add-on scaffolds, at least, consist of the first, second, and transitional areas between them, where the difference in the light path intersects the transitional area with the fraction that Is not an integer of the design wavelength.
