Leah names the two sons of Zilpah and is directly involved in their upbringing.Pirke De-Rabbi Eliezer, xxxvi.). Zilpah also figures in the competition between Jacob's wives to bear him sons.

Unlike the traditional light microscope, however, a confocal microscope slices thin, clean optical sections of a given specimen using either fluorescence or reflection.
They minimize or eliminate the need for reading glasses after surgery. Conventional monofocal lenses only correct for distance vision, meaning reading glasses are still needed after surgery. Multifocal IOLs (Intraocular Lens) can be an option in some patients to help improve both distance and near vision. Toric implants are available to correct astigmatism. A lens for better color vision is in development (shown here next to a dime).
