Cover the fluorescent bulb with an ultraviolet-absorbing safety sleeve. Many different manufacturers offer many different styles. Ultraviolet light is absorbed by almost everything, so they'll all work. In general, these sleeves are designed to fit tube lamps, but you can cut, form, and tape the lightweight plastic ones to go around a compact fluorescent tube as well.
Insert a plastic diffusion sheet in your box fixture. If you have a fluorescent tube box fixture, you can purchase plastic diffuser sheets that fit the fixture. Although these are designed to spread out light from the tubes, they also absorb infrared. You may also cut these sheets to fit other size fixtures.
Use a lampshade on your compact fluorescent fixtures. Ultraviolet light interacts very strongly with materials of many different sorts. If you use the lampshade so that your room is illuminated by light bouncing off the walls and ceiling, most of the remaining UV light will be absorbed by the paint on your walls.
