Even if you're looking for just one new reading lamp, you should think about how that lamp will work with existing light fixtures. The trick is to provide enough light for reading while ensuring sufficient ambient light (a room's general background lighting) to avoid severe contrast in light levels, which causes eyestrain.
For a sitting area , it's best to use an adjustable task lamp called a pharmacy lamp. Homeowners should be aware of specular surfaces: anything that might reflect light. For example, at night a window becomes a mirror. A table lamp will be reflected in the glass, and this could be disorienting.The pharmacy lamp is desirable because its slim profile and directional light source produce a very small pool of light. Swing-arm reading lamps mounted to the wall are another option to use in tandem with background lighting.
