Abstract

A component for a mobile computer device, such as a smartphone, can be secured to the housing of the mobile computer device. The component can deflect the light of a built-in light source of the mobile computer device with an optical element and optionally filter the same, or can provide its own light source to improve the option of measuring eccentric photorefraction using the mobile computer device.
