Make a portrait with reading glasses as a prop
Keep the person comfortable and the eyes readable.
Glasses can be part of a portrait rather than a problem to remove.
Begin with the sitter’s preference
Use glasses the person wants to wear and test the actual light. Adjust the light or comfortable head angle if reflections obscure the eyes. Do not insist that someone remove glasses needed to see the countdown or instructions. Keep spare prop eyewear optional.
Build a simple sequence
Try looking at the lens, glancing down and returning, without exaggerated movements. Review the exported crop and visible reflections. Choose the version the person likes; the goal is a useful portrait, not a rule that every lens surface must be perfectly reflection-free.
