Morphology
The meaning ('a removable cap that protects a lens') is directly and transparently derived from combining 'lens' (an optical element) with 'cover' (something that protects or covers). This noun–noun compound follows a common compositional pattern found across languages, so a B1 learner who knows both constituents will readily infer the MWE meaning.
Etymology
Lens cover is like a small 'hat' for your camera. The cover fits over the lens to keep dust and scratches away when you are not using it, so it means 'a removable cap that protects the lens'.
