I was diagnosed with blepharitis , the doctor told me to use warm compresses and it helps . but how can my vision to stop getting blurry due to oil ?

Artificial tears: Clean your eyelids and lashes with diluted baby shampoo twice a day to clean the oily glands. You can use artificial tear drops throughout the day to wash out the oily products.

Oils will normalize.: Make a sack out of a nylon stocking filled with uncooked converted rice. Heat this in a microwave for one minute. Apply it to your closed eyelids for 10-15 minutes. Make sure it is as hot as you can tolerate without actually burning your skin, as the eyelid skin is very thin. As time goes on, the oil secretions will normalize and the oils will have less of a tendency to cause blurring.
