A shopkeeper tells me that because I have -0.50 Cyl in one eye, it has to be converted to additional power/Sph and don't need to order special ones with the Cyl. In fact he says for that value of Cyl, there are no lenses from Bausch and Lomb. He mentioned that they only come for Cyl lenses for higher values.
Does any one know whether his statements are true?
