You absolutely can ask them that. Noticing it is not the same thing as getting distracted by it. Allowing your focus to be highjacked by the environment is a sign of a weak mind. If you went to work and a coworker told you the shape of your nose was distracting to them, and you need to wear a mask so they can continue to work, that is on the coworker, not you. It is absurd to put someone else in charge of what needs to be done to stop you from being distracted.

People need to control themselves, no one else has that ability.
