Usually, a seller will have at least one shot of the eyepieces in or next to the microscope, if they came in and/or were with it. The description makes me think eyepieces are added before shipment.
Two words, "clean optics" would be nice to read, or seeing some sharp, well-exposed photos of the lens surfaces. Looking at the objectives photos, I personally would ask the seller about the optics and optical performance, or an easy return policy: to reduce the chance of a NAD return and effort of documenting aspects that should have been in the description (the seller's job).
