Morphology
The meaning 'a lens used with light or optical devices' is directly and transparently derived from combining 'optical' (relating to light/vision) with 'lens' (a device that focuses or directs light). This straightforward compositional relationship is common in English and other languages, so a B1 learner who knows both constituents would readily understand the MWE.
Etymology
Optical lens combines optical (about 'sight') and lens. One popular story says early glass pieces were shaped like small lentils, so people called them lens, and because these curved pieces bend and focus light, optical lens now means 'a clear piece that focuses or spreads light'.
