METHOD OF FORMING A PHOTOCHROMIC SEGMENTED MULTIFOCAL LENS |
摘要 |
A method of forming a photochromic segmented multifocal lens is described. The method involves, forming a segmented multifocal lens blank by molding, in which the segmented multifocal lens blank has a front surface and a rear surface. The front surface of the segmented multifocal lens blank includes a segmented optical power addition portion. The method further includes, grinding the rear surface of the segmented multifocal lens blank, thereby forming a segmented multifocal finished lens having a front surface and a rear surface. The front surface of the segmented multifocal finished lens includes the segmented optical power addition portion. The method additionally includes, forming a photochromic coating layer over at least a portion of the rear surface of the segmented multifocal finished lens. The photochromic coating layer includes at least one photochromic compound. |
