In the past two weeks or so I've been getting a weird and worrying
sensation in my left eye. It's a sort of tingling, tickling, even
dragging feeling that comes briefly and then goes, worse some days
than other. Sometimes hours pass without it, then it comes back. I
think it has been getting more frequent over time. It feels as if it
is inside rather than on the eye. I wear semi-permeable rigid contact
lenses, am pretty scrupulous about cleaning and disinfecting them with
Boston solutions, and I thought maybe it was something to do with the
lenses but even when I have left them off for a few days and worn
glasses instead the sensation persists. Could I have some kind of
parasite inside the eye? It does feel sometimes almost as if a tiny
thing is wriggling in there. I am in my 50s, have always had quite
protuberant eyes (a hereditary feature; thyroid has been within normal
up to last check around three years ago). My actual sight doesn't seem
to be affected, and there is no more redness, watering or irritation
than usual. I wear a lick of mascara daily. Any ideas? I live in the
UK. I work at a screen for long hours; yesterday for example for 16
hours, but this doesn't feel like eye strain.
