Oil is good!: The tear film is made up of a balance between the aqueous (water), oil, and mucus. So, warm compresses allow the oil glands to open up, and keep the tear film on your eyes longer , to prevent against evaporation. Otherwise, you'll end up with styes. So, you are practicing good lid hygiene. Warm, not hot compresses are better for eyes, and more comfortable. You should see better using less heat.
