Abstract

Using the Cameron Tangimetric Campigraph four subjects were tested morning and evening to determine the size of the retinal fields for blue, red and green lights projected through an opaque screen. Morning and evening records were then compared to find the amount and character of the changes. Percentages of increase or decrease in the size of the fields were computed in terms of the distance along twelve radii from the fixation spot.
