A classically trained optometrist will have a large mask that can accept lenses from a special tray with tiny handles on them. These lenses can be popped in and out and combined with other lenses to make "instant glasses" You can wear it, take it outside, read music for half an hour to see if the prescription is ideal. Most doctors have a kind of twenty minute time limit, so they just check the prescription using an eye chart. The eye chart is good, but it isn't music.
