Re-reflections in lens lenses from a strong light source
The lens consists of a set of lenses (in some lenses - of mirrors), designed for mutual compensation of aberrations and assembled into a single system.
From the contour light (bright light sources behind the subject or next to it), caught in the frame or located outside the frame, parasitic reflections from the internal elements of the lens are formed, called glare (or in slang "hares").
