The "hide" and "swap" buttons that appear in the main hud of [[Arknights]], used as a button to hide the "secretary" character (displayed character chosen by player on the home screen).

They have been popularized as censors due to "a screenshot":[/media_assets/7524102] featuring [[La pluma (summer flowers) (arknights)|La Pluma]]'s skin, where the top of her bikini is hidden by them, making it look like she's not wearing one.

Also popularly used as glasses due to similar ingame arrangements placing them over the eyes.
