Classic Round Eyeglasses Illustration - Vintage Optical Design #207121 (License: Personal Use)

This monochrome illustration features a pair of classic round eyeglasses with thick, slightly curved frames, prominent nose pads, and straight temple arms ending in tapered earpieces. The lenses include subtle cross-hatching to suggest transparency and depth, while the overall style mimics hand-drawn technical sketches or vintage optician diagrams. The clean lines and absence of color emphasize form and function over realism.
