I had blepharitis. Tears consist of mostly water and some oil to keep them from evaporating and some mucus to stick them to the eye. In this condition the 3 separate and the oil ends up clogging the tears ducts causing swelling/infection and the eyes feel super dry. The simple solution for me was to wash my eyes daily (morning and night) with a little diluted baby shampoo. Baby shampoo is the pH of your eye so it does not sting, it removes the germs, and the warm water dissolves the clogged oil. I used to fold a wash cloth and hold it under water as hot as my face could stand, hang my face over the sink, press the wet hot wash cloth against both my closed eyes for a minute or so and let the water drip out while I gently squeezed it against my eyes, then rub the cloth with closed eyes along the lash line (once of each eye), then simply tip a travel size Johnson & Johnson baby shampoo bottle against my index finger and the amount that stuck to my fingertip after righting the bottle was all that was needed for both eyes (rub both index fingers together and use one finger for each closed eye and wash back and forth along the lash line). Then use the warm wash cloth with fresh water without wringing it against both eyes at once again and squeeze the washcloth to let water rinse the baby shampoo away (may need to do this a few times). I did this ritual morning and night for a few years and then at an eye doctor's appointment with a new doctor mentioned I had blepharatis and he said he saw no evidence of it. So I guess it can go away. Untreated it would cause the tear ducts of my eye lids to clog and have little white bumps along the inside of the lash line, as well as swelling of the whole lid until it was red. I did not notice a correlation between the clogged lids and being sick, I had it all the time. However, the baby shampoo washing became such an easy routine that it prevented the occurrences. I would go see an eye doctor if you have not yet since a primary care knows less about eyes. But the routine above completely kept my infections away and seemed to even clear up the condition altogether (or I just got older an my chemistry changed). Good luck.
