A lens-sensor array for imaging parts of an eye comprises a lens arraydisposed onto a sensor array. The lens arraytransmits a light from a lens towards the sensor array. The lens arraycomprises a first section configured to direct the light reflectedby a first part of the eye to the sensor array, and a second sectionconfigured to direct the light reflected by a second part of the eye tothe sensor array. The first section comprises first sub-sections, each firstsub-section comprising at least one first lenslet. The secondsection comprises second sub-sections, each second sub-section comprising atleast one second lenslet. The sensor array comprisessensors that detect the light from the lens array and generate sensor signalscorresponding to the light reflected by the first part of theeye and the light reflected by the second part of the eye.
