Hello. Thank you for coming to JustAnswer with your question, and welcome.
The description you are giving of your symptoms sounds like a condition called "blepharitis".
Here is a link that explains: Blepharitis
Some people have very irritating symptoms (redness, swelling, itching, crusting, etc) because of this. Some people have few symptoms other than the little blisters that form on the edge of the eyelid.
You can try caring for this at home by cleaning your eyelids, specifically the edge of the eyelid, with a very clean, warm washcloth. Adding a bit of baby shampoo can be helpful as well. Gently "scrub" the edge of your eyelid, where your eyelashes are, which keeps the very small ducts open and clear. You can also get disposable eyelid scrub pads from your local pharmacy that already have a solution in them. Do this once a day (twice at most) and see if that doesn't clear it up.
The link I gave you also has directions for cleaning your lids.
If this does not work, see your doctor or eye care specialist for further investigation and treatment.
