If you’re in the need of some new glasses there are a large number of shops to choose from, the one I chose was Grand Optics. The eye exam was done very professionally using computerised equipment as well as a survey of what activities I would be doing with the glasses. The service is next day.

Grand Optics on the corner of Norodom Boulevard & St 154.

Free eye tests with no modern bells or whistles but certainly competent.
Wide selection of frames and lenses imported from across the world.
