We know that tear is very important to eyes. It is produced by glands in eyelids. Besides of water, it also contains lipids, mucus, anti-bacteria agents and protein. It could lubricate, clean, nourish eyes, kill bacteria in eyes and provide oxygen to eyes. If the glands are blocked, you might get blepharitis. First of all, you need to know blepharitis is a chronic disease although sometimes it tends to come and go naturally. You can apply some home remedies to help relieve it. Warm compress is good for blepharitis, because the warmth could help melt the oil congened in glands and make it produce lipids out. Clean the eyelids margin with warm water with baby shampoo or bicarobonate of soda. Soak a cotton bud in the solution and then clean the eyelids margin carefully and tenderly. Never try to sqeeze if you see any bump on the eyelid margin, which might make the infection or inflammation worse. And then you could massage your eyes tenderly with your fingertips (which should be cleaned thoroughly) or the cotton bud soaked with solution I introduced earlier. If necessary, you can get some anti-biotics ointment or some steroids eye drops to help.
