This can cause your pupils to be different at times.
The itch and burning is a separate issue, perhaps blepharitis
and mild dry eyes
. Try this:
Blepharitis is a condition where glands in the eyelids are not functioning normally. They become plugged and instead of putting out their normal clear, oily secretions, they put out thick, toothpaste like gunk. You may not be able to see this “gunk” yourself, unless it is really bad, but it shows up clearly on slit lamp examination.
The best treatment for this condition daily lid scrubs combined with warm compresses. I like to use baby shampoo for lid scrubs. In the shower, place the shampoo on your index fingers, close your eyes, raise your eyebrows (to stretch the skin on your eyelids) and scrub back and forth along your eyelashes for 3 to 5 minutes. The hot water in the shower helps to soften the plugged oils in the glands while the mechanical scrubbing with your soapy fingers removes the oils.
It is now safe to press that Pretty Green Button so that my poor, starving, barefoot, daughters can buy new shoes and, once again, feel safe from the mean, nasty snakes, as they walk through the tall grass.
