By default all views are Public, meaning they can be accessed by anyone who has access to the workbook. With view permissions, you can now set specific views to Private, which then allows you to select which users do not have access (note that Owners of the workbook, or the folder it lives in, always have access to all views).

From the permissions menu, you can change a view from Public to Private, and specify exactly who will have view access. For instance, in the animation below, we remove view access from Peter, Roger, and Harry.
