Morphology
The meaning 'a lens that is thicker in the middle and focuses light' is directly derived from combining 'convex' (curving outward/thicker in the middle) with 'lens' (a device that focuses or directs light). This is a straightforward, technical compositional pairing that is cross-linguistically common, so a B1 learner who knows both constituents should be able to infer the MWE meaning.
Etymology
Convex lens shows its meaning: convex means bulging out and lens is a piece of glass that bends light. The bulging middle makes light rays meet at one spot, so the lens 'focuses' light and can 'make things look bigger'.
