The American Academy of Ophthalmology said in the statement that the pressure inside the champagne bottle is as high as 90 pounds per square inch, which is equivalent to 6.12 atmospheres or 6.205 bars, which exceeds the tire pressure of a small car. This pressure allows the stopper to fly off the bottle at a speed of 80 kilometers per hour, which is difficult to avoid in time. If it hits the eye, it is "enough to cause permanent damage to vision."

At festivals, some people like to celebrate with champagne. The American Ophthalmology Association issued a statement to remind the public that caution should be exercised when opening champagne and beware of bottle stoppers. The American Ophthalmological Society also released a video showing that the power of champagne stoppers can break the glass.
The distance between the bottle and the person is usually 60 cm when the champagne is opened. It is calculated that the time for the stopper to reach the eyes is less than 0.05 seconds. Most champagne bottles sold in the United States have warning labels on them to remind consumers to protect their eyes when opening bottles.
The British Journal of Ophthalmology published a research report that a bottle of 750 milliliters of champagne contains 4.125 litres of carbon dioxide, and the pressure inside the bottle reaches 6.2 bars, allowing a 30-gram bottle stopper to fly out of 13 meters.
