The League of american football (NFL) has partnered with the manufacturer of Oakley sunglasses in order to design helmets with eye protection and mouth, in order to limit the spread of the coronavirus in the field, reported on Monday the american media.

The prototype of a helmet includes a visor and a shield “buccal” of plastic, with holes to allow the passage of air at the nose and mouth. The goal is to stop the transmission of droplets, explained to ESPN’s Jeff Crandall, president of the board of engineering of the NFL. The medical director of the players Association, Thom Mayer, recognizes that visibility and the ability to breathe are the two main concerns. “We have tested with a few of 2,500 players in the league, but I’m surprised that claustrophobia was not a problem until now “, he explained.
