What does it mean if you see this symbol on an airplane safety card? A passenger is unable to understand it.

Knowing airplane safety procedures in case of an emergency is vitally important to avoid any setbacks in the event of a problem on board. This is not only the responsibility of the pilots and other crew members; all passengers taking a flight in Spain should know what to do in the event of a dangerous situation.
To this end, airlines always leave safety cards on their seats for all passengers to read carefully, something flight attendants also encourage when explaining safety protocols just before takeoff. However, sometimes some concepts can be a bit odd and confuse travelers, as happened to a person from the United Kingdom flying with Ryanair who came across some very peculiar symbols.
Icons on aircraft safety cards
The British passenger posted a photo of the Ryanair security card on Reddit for his flight, and in addition to more common symbols like a suitcase, a no-smoking sign, and high-heeled shoes, he came across two other icons that left him perplexed: one showed a pair of glasses next to a strange object, while the drawings on the other were practically indecipherable.
The traveler asked other social media users about the true meaning of these symbols, and although some made a couple of sarcastic comments, one cleared up any doubts with his response. No, they're not steaks or slices of cake, but rather objects that cannot be worn when using the emergency slide, should the need arise.

The social media user explained that the icon in the upper right corner depicts an ear with earrings and a woman with a necklace, which means that all jewelry must be removed when jumping down the evacuation slide in the event of an emergency. The symbol, of course, didn't make it clear to passengers what it actually meant.
On the other hand, the one in the lower left corner, where you can see glasses, indicates that you must remove them before sliding, although next to it is a slightly strange object. What is it? Well, it's nothing more than a set of false teeth, intended to indicate to all users that those who have one on should take it out before jumping.
