Abstract
A head-mountable device can include a light seal element with adjustable opacity. In various configurations of the light seal element, the opacity there through can be adjusted to control an amount of light and/or airflow from an external environment. For example a cover or combination of overlapping covers can be adjusted to selectively exclude light from an external environment or provide a direct view to the external environment. Transitions can be achieved while the head-mountable device is worn by a user.
