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.
I have just been looking through the pages of the link you gave me. Although, thankfully, I do not have any of the conditions in the photos, I do have dryness of the eye
periodically, something I have been noticing, recently.
I have been staying with my daughter who lives on a farm. The farmer uses a mixture of 'light' style surveillance equipment involving radium and plutonium. He is not mentally sound and fires the equipment indescriminately. I notice the 'dryness' in my eyes when he is having a 'mad run', often in the night, when we are trying to sleep.
I have been buying cheap magnifying lenses, too. I have not been used to glasses before, although I do try to disinfect them. Maybe my problem is dust mites. I am prone to hay faver attacks at the farm house which has been there since 1700. I expect it has good selection of resident pests.
Thankyou for your diagnosis. I have read the details about self-treatment.
I am relieved to find out it is not a sign of an eye tumour, today.
