First you have a chronic problem and it's possible that you need to think along the lines of "control" rather than cure.
Second it does not fit the description of a chronic conjunctivitis which is relatively unusual
Third it does fit the description of a combined blepharitis-dry eye. (all except the problem with night vision and better vision looking through a hole (the well known pin-hole effect) that sounds like a low grade refractive error usually myopia and is helped by glasses at night.
Would suggest you use the search features and archives and "Today's Pulse" on this page (scroll through all the papers by clicking on blue dots) and read about "dry eyes" and "blepharitis" and begin Rx of same.
There are medical conditions such as over-active thyroid that can cause this. When you're able see a cornea-external disease specialist, suggest Bascom Palmer Eye Institute of U of Miami. Bring summary of previous visits.
Thank you for your reply. I looked up blepharitis and besides the symptoms listed I have no other (no discharge, no tiny flakes, no swelling); can blepharitis be contagious? I've read that blepharitis means that something is wrong with me internally (poor health) and often there is no cure, just keeping it under control, is the first part true (poor health) ?
Also, I've done my blood work and included the thyroid hormones twice 6-7 months apart and they resulted normal. Is it possible to have hyperthyroidism which doesn't show on the blood tests? I asked for the test because 6 years ago I developed a weird cold intolerance (I discovered that this may be due to stress, anxiety and depression as I do suffer from them).
This is as much as I can tell you in an internet forum.
