Nobody in particular.
My shooting glasses are prescription glasses but slightly different than the ones I am normally required to wear. It would be senseless to use any other glasses. I couldn't see the targets :-)
The eye protection they provide was chosen for the wrap-around side coverage and to fit over the top of whatever shooting glasses you normally wear. I wear prescription glasses myself and their safety eye protection fit over mine OK. If one's shooting glasses are very large frame and large lenses there might be interference.
I asked the RSO who accompanied me if the safety eyeware and hearing protection was single use, since you deposit each into collection drums upon leaving the range area, but he said no. They are collected after use and are cleaned and sanitized by some process and returned to stock. I didn't ask about the details of how that is accomplished.
