1. A system for determining a risk indicator for myopia, the system comprising:
a wearable device configured to be attached to a body of a user, the wearable device comprising at least one distance sensor configured to determine at least a first distance value indicative of a distance between the wearable device and an object located in a central vision zone of the user and a second distance value indicative of a distance between the wearable device and an object located in a peripheral vision zone of the user;
a control unit configured to determine, based on the first distance value and the second distance value, a risk indicator for myopia.
