My eyes are always red and at times feel very tired. As a substitue teacher, often times, I am in different classrooms. So I use a lot of Visine to try to keep them clear which usually doesn t work. By the end of the day my eyes are almost bloodshot red and feel sore and tired. Surprisingly today, I was in a room where the teacher had a diffuser going for about 2 hours. By the end of the day, my eyes were not red nor did they feel sore and tired. Would the diffuser have anything to do with this possible revelation of relief?
