उत्तर
The given sentence is wrong.
Explanation:
An “endoscopic magnifying glass” is not a real device used for vision correction. Endoscopes are medical instruments used to examine the interior of a hollow organ or cavity of the body. Vision defects (like myopia, hypermetropia, or presbyopia) are corrected using standard optical lenses (concave, convex, or cylindrical).
