Answer: B - Rigid gas permeable (RPG) contact lenses resist deposit buildup and generally provide clearer, crisper vision.

Rigid gas permeable lenses are easier for the wearer to handle, resit deposit buildup, provide crisp vision, and are less likely to tear. It may take the wearer longer to get used to RPGs as they are less comfortable initially as soft contacts. Since they last longer, they may be less expensive over the life of the lens.
