The invention is concerned with a method for protecting an optical sensor (20) of a vehicle (10), wherein the sensor (20) is protected from environmental pollutants (40) which adhere to an optical surface (30) of the sensor (20) if the sensor (20) is exposed to them, and wherein the environmental pollutants are kept away from the sensor (20) by an ultrasonic cleaning of the sensor (20) surface using an ultrasonic field. The ultrasonic field of the ultrasonic cleaning is emitted by a protection device (60) into the air to provide a protection zone (50) around the optical surface (30) of the sensor (20) such that a contact of the optical surface (30) with the environmental pollutants (40) is avoided, wherein the environmental pollutants (40) are moved and/or destroyed in the air away from the sensor (20) if they enter the protection zone (50), and wherein the protection zone (50) provides a contactless cleaning of the sensor (20)
