• Electroretinograms of 11 healthy eyes were recorded on two occasions. Four different electrodes were used, and the B-wave amplitudes were compared. The Lovac contact lens electrode produced higher amplitudes than did the ERG-Jet lens electrode or the Burian-Allen lens electrode. The gold foil electrode gave the lowest amplitudes, but was superior in comfort.
