The present application relates to a method for measuring the risk of dry eye. The method may include receiving first sensing data formed by sensing a set area in a body of a user and receiving first risk factor information related to the user. The method may also include outputting first blink information related to blinking of the user, on the basis of the first sensing data and calculating a first weighted value corresponding to the first risk factor information, on the basis of a relationship between one or more pieces of the received first risk factor information and a risk degree. The method may further include calculating a first risk of dry eye of the user by combining the first blink information and the first weighted value, and providing the first risk of dry eye through an input/output device.
