Coffee 'could prevent eye tremor'

Drinking coffee protects against an eyelid spasm that can lead to blindness, a study suggests.

Italian researchers looked at the coffee drinking and smoking habits of 166 people with blepharospasm. Sufferers have uncontrollable twitching of the eyelid which, in extreme cases, stops them being able to see.

One or two cups of coffee a day seemed to reduce the risk of the condition, the team reported in the Journal of Neurology, Neurosurgery and Psychiatry.
