Getting “egged” can cause serious damage, according to research.

A Liverpool-based study found that being pelted by a raw egg may result in eye injury – and could even lead to blindness.

Researchers from Royal Liverpool University Hospital looked at the records of 18,651 patients who had attended an eye unit over a 14-month period.

They discovered that 13 people had been the victims of an egg attack.

Many of these cases were clustered around Halloween, and 12 of the patients were men.

Eight had serious injuries to their eyes, including detachment of the retina, macular damage and raised internal pressure, which can lead to a permanent loss of eyesight.

While most recovered, one of the patients, who had been hit from an egg thrown from a passing car, suffered permanent damage to his eye.
