drooping eyelids periodically through out the day

hi there. im 33 years old. and a little over a month ago i started experiencing my eyelids drooping to halfway. each time it happens it lasts roughly 3 minutes then returns back to normal. my vision is not changing, that remains the same. it happens a fare few times through out the day and evening, any ideas as to whats going on? answers much appreciated, thankyou.

There is a long list of reasons, but the thing that comes to mind is Myasthenia Gravis. Please make an appointment to be seen in the next few weeks with an ophthalmologist.
