To the Editor.  —There has been an awareness for some time that repeated exposures to high energy microwave radiation may produce biological injury. Particularly prone to such injury are poorly vascularized tissues of the body such as the lens. A continuing study of radar workers, in progress for nearly ten years, has led to the observation that a disproportionately high incidence of cataracts or precataractous changes have already occurred in a relatively young group of men.With the increasing use of microwave equipment, there is an increased likelihood of injury due to inadvertent exposure. Microwaves are now being widely used in commercial applications, such as drying of wood or cooking of potato chips, as well as in communications or radar ranging operations. In addition, microwave ovens are being introduced into homes at an increasing rate as advancing technology allows for price reduction.Although heating is the primary physical result of
