Blepharitis is basically a catch all for any issues related to lipid production by the eye lid. Basically what happens in your eye is you produce tears and you also have glands that produce oil. The oil becomes a coating over the tears so they don't evaporate. Blepharitis essentially means your glands aren't producing enough/any oil and so the tears dry up really fast. I disagree with the diagnosis because it doesn't fit with the symptoms. My eyes actually don't feel all that dry like real dry eye suffers describe the sensation. The discomfort is a definite strain. My eyes are relatively discomfort free when I am not looking at a computer screen or in "bad" lighting. But as soon as I look at a computer screen or TV, it's an immediate discomfort. Through out the day I can feel the muscles in my eyes becoming weaker and weaker to the point where they feel almost useless. It is difficult to describe but imagine you do bicep curls until failure, for 3 years every day. You can feel the bicep, but it just doesn't work. In fact I can sense muscles in my entire face reaching back to my ears and down to my cheek bone. Muscles I never even noticed. Also one eye is definitely weaker than the other and if I completely relaxing them it closes about 50% more than the other and feels like there is a weight hanging off of my eye brow. So I really think it is muscular and tear production or oil production is a side effect. If I fix the strain, I fix the dry eyes.
