Various implementations disclosed herein include devices, systems, and methods that determine eye characteristics (e.g., gaze direction, eye orientation, etc.) based on the determined flash position. For example, an exemplary process may include: generating a flash by generating light reflected from a portion of an eye; receiving the reflected light at a sensor, where the reflected light is received after passing through a multi-zone lens having a first zone and a second zone, the first zone and the second zone having different energy diffusion characteristics; determining a location of the flash based on the reflected light received at the sensor; and determining an eye characteristic based on the determined position of the flash. 本文所公开的各种具体实施包括基于所确定的闪光位置来确定眼睛特性(例如，注视方向、眼睛取向等)的设备、系统和方法。例如，示例性过程可包括：通过产生从眼睛的一部分反射的光来产生闪光；在传感器处接收该反射光，其中该反射光在穿过具有第一区和第二区的多区透镜之后被接收，该第一区和第二区具有不同的能量扩散特性；基于在该传感器处接收的该反射光来确定该闪光的位置；以及基于所确定的该闪光的位置来确定眼睛特性。
