I don't know, I'm not a doctor, but it is possible you could have blepharospasm. Usually, this presents in older women in conjunction with dry eye, but there are some doctors who feel that eyelid muscle problems in conditions such as Myasthenia Gravis may be an alternate trigger for this condition. This link offers an opinion on this, if you scroll down through the comments to the one by Roger Kurlan.

Many people get dry eye, but only a small percentage will develop blepharospasm. I imagine it is the same with eyelid weakness; a small percentage of patients with ptosis, double vision, etc. may also develop blepharospasm. Unfortunately, the treatment of choice for blepharospasm is Botox injections, which are contraindicated in MG.
