THE EFFECTS OF VARYING LEVELS OF ALCOHOL ON DARK ADAPTATION TIME

THE EFFECT OF ALCOHOL ON THE ABILITY TO DETECT A LOW CONTRAST TARGET UNDER MESOPIC LEVELS OF ILLUMINATION WAS INVESTIGATED. DARK ADAPTATION TIMES WERE OBTAINED FOR EACH OF THREE BLOOD ALCOHOL LEVELS (B.A.L.'S)-80 MG%, 60 MG%, AND 40 MG%-AND A NORMAL CONDITION. ANALYSIS OF RESPONSE TIMES DURING THE PROCESS OF DARK ADAPTATION (AFTER ALLOWING FOR REACTION TIME) SHOWED SIGNIFICANT IMPAIRMENT UNDER 80 MG% B.A.L., WHILE LITTLE OR NO DETERIORATION OCCURRED AT 60 MG% AND 40 MG% WHEN COMPARED WITH NORMAL SESSIONS. /AUTHOR/
