Abstract
Information about changes in vision over time is useful to determine the health of a user. An electronic device has a display that presents visual information to a user. A sensor generates distance data that is used to determine a distance between the user and the display at particular times. Other data may also be acquired that is indicative of whether the user is wearing glasses, tilt of the user's head relative to the display, ambient light level, display brightness, what is being presented on the display such as video content or text content, font size, and so forth. The data is used to determine if the user's vision has changed beyond a threshold amount. If so, an action may be taken, such as providing a recommendation to the user. For example, the user may be advised to consult a health care provider.
