People who drink coffee are less likely to develop an involuntary eye spasm called primary late onset blepharospasm, which makes them blink uncontrollably and can leave them effectively ‘blind’, according to a study published online ahead of print in the Journal of Neurology Neurosurgery and Psychiatry.Click here to view the paper in full: http://press.psprings.co.uk/jnnp/june/jn119891 press release.pdf
The effect was proportional to the amount of coffee drank and one to two cups per day were needed for the protective effect to be seen. The age of onset of the spasm was also found to be later in patient who drank more coffee – 1.7 years for each additional cup per day....‘The most obvious candidate for the protective effect is caffeine, but the low frequency of decaffeinated coffee intake in Italy prevented us from examining the effects of caffeine on blepharospasm.
They suggest that caffeine blocks adenosine receptors as has been proposed for its mechanism in protecting against Parkinson’s disease.
The authors estimate that people need to drink one to two cups of coffee per day for the protective effect to be seen.
‘Considering that the caffeine content of a cup of Italian coffee (60–120 mg) is similar to the average content of a cup of American coffee (95–125 mg), the protective effect on the development of blepharospasm might be exerted at caffeine doses greater than 120–240 mg, comparable with the caffeine doses suggested to be protective in Parkinson’s disease,’ they say.

Coffee can help prevent blindness
The jury's still out on coffee and fertility, but the more I look into it, coffee is not as bad for you as people think (it could be the icky pesticides and the dioxin-y filter--free trade organic French press for me, please)--its been shown to help regulate insulin levels, prevent gout, and now look at this is from the Journal of Neurology Neurosurgery and Psychiatry:
