Academics Highlight Risks of Cork Launches and Share Safety Tips to Protect Vision

Experts have issued a warning about the dangers of eye injuries caused by corks when opening bottles of sparkling wine or Champagne, especially during celebratory occasions. Researchers from the University of Cambridge’s Department of Ophthalmology, including Ethan Waisberg, have cautioned that corks can be propelled from bottles at speeds of up to 50 miles per hour, posing a significant risk of serious eye damage, including permanent blindness.

While the advice may seem overly cautious, the academics stress that cork-related injuries are often underestimated and can lead to severe outcomes, such as detached retinas or lens dislocation. The pressure inside a 750ml bottle of Champagne or sparkling wine is three times that of a standard car tyre, and this intense pressure can propel the cork up to 13 metres in under 0.05 seconds. This speed is so fast that the blink reflex cannot prevent injury, potentially causing lasting harm to vision.

To minimise the risk of injury, experts have outlined simple safety measures, in line with recommendations from the American Academy of Ophthalmology. These include chilling the bottle before opening it to reduce pressure, holding the bottle at a 45-degree angle away from yourself and others, and gently pressing down on the cork to counter its upward force. In the event of an injury, seeking immediate consultation with an ophthalmologist is essential to limit long-term vision damage.

The researchers also advocate for increased public awareness and preventive steps, such as warning labels and alternative bottle closures like screw caps. They referenced a 2022 incident in which cyclist Biniam Girmay suffered an eye injury when opening a bottle of prosecco on the podium after winning the Giro d’Italia, forcing him to withdraw from the competition.

Previous studies have highlighted the prevalence of eye injuries from corks, with one 2005 study finding that Champagne corks were responsible for 20% of eye injuries related to bottle tops in the US and 71% in Hungary. While many individuals recovered, the study revealed that 26% of cases involving pressurised bottles resulted in legal blindness. A 2009 review of 34 cork-related eye injuries in Italy found a range of serious conditions, including traumatic cataracts, bleeding, and glaucoma.

In their article in the BMJ, the authors emphasise the importance of taking precautions to avoid the need for eye surgery in the new year. Their message is clear: enjoy the festivities but ensure that the cork stays in the bottle, so your sparkle remains in your eyes.
