Does the serial number contain the diopter of the sunglasses?

Hello, I got a 9271 Flak 2.0，but comparing to my previous Gascan，it looks a little bit fuzzy, so I am just wondering whether I can get the diopter by checking the product serial number, thanks...

Sunglasses typically have plano lenses that dont have any vision correction, so they dont have a diopter. The only way to get vision correction is to order them specificly with it from an optometrist or lux.

Now, the model you have is a lower bridge fit model, so if you dont require that fit, it may sit strangly or your face. Whether that creates a issue with clarity, I can't say.
