Experts are calling for cigarette packets to carry a warning that smoking can cause blindness following the discovery that smoking and passive smoking can cause age-related macular degeneration (AMD), the leading cause of blindness.
The unpublished European Eye Study of 5,000 patients in the EU found 27 percent had diseases directly linked to smoking.
The Royal College of Ophthalmologists has called on the government to add a "Smoking causes blindness" warning to cigarette packets.
