In people with primary late onset blepharospasm, the eyelid muscles contract uncontrollably and cause involuntary blinking. In extreme cases, people are unable to prevent their eyelids from clamping shut and, despite having healthy eyes, they become functionally blind. Late-onset blepharospasm usually strikes people in their 40s and 50s and belongs to a class of disorders known as dystonias that involve involuntary muscle contractions. Other types of dystonia include writer's cramp and musician's cramp.

Coffee and belpharospasm
Dr. Giovanni Defazio of the University of Bari, believes drinking coffee could reduce the symptoms of blepharospasm.
One to two cups of coffee a day help protect against late onset blepharospasm. Considering that the caffeine content of a cup of Italian coffee (60-120 milligrams) is similar to the average content of a cup of American coffee (95-125 milligrams), the protective effect on the development of blepharospasm may be exerted at caffeine doses greater than 120-240 milligrams, comparable with the caffeine doses suggested to be protective against Parkinson's disease.
