Using an infra‐red camera AGA 680 the temperature of the cornea of men and rabbits was measured with a precision of ±0.1°C. The subjects were moved from normal room temperature into a cold chamber with temperatures of 0°C and ‐10°C. The material was divided and mean corneal temperatures were recorded at various times as follows: The frequency of blinking is low in rabbit compared to that of man. On the basis of present data it is obvious that the corneal temperature is a function not only of the ambient temperature, but also of body temperature and blinking. It is supposed that there is an additional factor responsible for more rapid cooling in the human cornea than in a rabbit's. This factor might be the smaller amount of aqueous humor behind the cornea, in which case the corresponding thermal capacity will also be smaller. Using a test animal lacks the advantage of co‐operation during the test. The physical nature of using the infra‐red camera in measuring the temperature of the cornea is briefly discussed.
