An electrophysiological study was made concerning the effects on the cerebral blood flow of rabbits by application of contact lens. The results obtained are as follows;
I. In about 50% of the cases, the cerebral blood flow increased by application of contact lens. However, in about 33% of the cases, the cerebral blood flow decreased.
2. It was assumed that the increase of cerebral blood flow was due to the decrease of activity of the reticular formation, which was elicited from the contact lens, and that the decrease of cerebral blood flow was due: to the increase of activity of the reticular formation.
3. It was understood that the decrease of cerebral blood flow might explain the symptoms observed in those who have difficulty in wearing contact lenses.
