Foster Grant Multi-Focus Charlsie Dark Brown reading glasses are chic and sophisticated. This sleek design features a satin brown metal frame front and lightly tapered tortoise acetate temples. Multi-Focus Reading glasses utilize three different strength prescriptions in one pair of reading glasses. The bottom of the lens features the selected power for reading. The middle of the lens features a prescription slightly less than normal reading strength designed for computer use. The top of the lens features half the strength of the reading power for interacting with others.
