First you can diagnose your face here:

and determine what type of problem you might have. How long have you been eating macrobitically? Did you eat yin or yang mainly before?
According to TCM "The liver nourishes the eyes. The kidneys give the power of sight. Dry itchy eyes, are usually liver blood deficiency. If there is redness it means liver heat." They also know of some relationship between the right & left eye but I don't know what it is.
Maybe this will help.
