The retinal action potential in the white-eyed mutant mosquito has been recorded and, according to data obtained through electrophysiologic and electron microscopic technics, does not appear qualitatively different from that previously recorded in the pigmented eye of the Rockefeller strain of this mosquito Aedes aegypti L.. Of the two types, the white-eyed mutant is, however, more sensitive to light because no light-screening pigment granules are present to isolate the ommatidia from each other. Light entering from various angles can stimulate an ommatidium or several ommatidia. As a result, the directional sensitivity of the eye decreases. More research is needed to confirm the probability that the resolving power i.e., visual acuity of the white-eyed mutant is considerably less than that of its pigmented counterpart. Author
