Hi Lucy - No, I have no explanation at all. Last night happened similar, though not quite so bad. Sooooo hate it when my eyes go funny. If it happens again then I'll phone the hospital and get me to see the eye specialist - she's nice thought the hospital is third rate. This was the place that screwed up my endoscopy & colonoscopy big time. And their rheumy is thick as short planks, suffering from inflated ego and culpable ignorance. GGggrrrrrr. (I sure do miss my UK consultants. Sigh.)
Anyways, thanks for asking hon. Glad to learn that yr doc sorted yr problem. Those lubricating drops are ace. Swear by mine. I also have Lucri-Lube ointment for night time when eyes are particularly aggravated - which will be happening about now time due to central heating and dry atmosphere. Eyes dry out quickly.
Take care -
Molly C (France)
