To the Editor.
—Zimmerman1 suggests that ophthalmic care commands an inappropriately large (9% ) share of national health expenditures. One can only wonder how he comes to that conclusion. Even if unnecessary eye care is being provided in this country, as he goes on to allege, Dr Zimmerman will agree, surely, that the amount expended for a commodity is, in the main, determined by the marketplace. The public decides on the basis of need how much to invest in eye care.
