Hi,
Does or has anyone had an issue with their eyes whereby they just seem to keep closing by themselves. It’s not painful. I just can’t keep them open. I think it’s a condition called Blepharospasm that causes involuntary closing of the eyelids.
It can be treated with Botox injections in the eyelids 
it happened a few months ago but then cleared up but has started up again. It’s very irritating
If you haven’t yet tried Botox, consider it…I had a Botox injection into eye muscle (local anaesthetic), unfortunately it didn’t change my chronic condition (Iritis/double vision) but this medication is known to be helpful in some cases.
