The term for excessive blinking is called blepharospasm. There is a condition called Benign Essential Blepharospam which occurs in about 1 out of 300 people over 40 years old. This can be very bothersome and can be treated with botox injections. The blepharospam is usually present in both eyes however.

Having it in only one eye as in your case is more concerning. There is another condition called Hemifacial Spasm. This is caused by irritation of the 7th cranial nerve which controls the facial muscles on one side of the face. Often, the nerve irritation is due to compression of the nerve by a blood vessel. MRI is often needed in these cases. Because of your excessive blinking on one side, I recommend you see an ophthalmologist for evaluation of hemifacial spasm with possible MRI.
