Florescent lights produce light from the Blue light spectrum. The standard house light or incandescent bulb produces light from the red side of the light spectrum. The problem is that glare tends to increase when light is produced from the blue side of the spectrum. The general guidelines for lighting indicate that 1,000 lux is necessary for reading and 500-750 lux for computer work. Of course, we tend to complete both tasks throughout the day complicating matters.
Solutions are often simple and inexpensive.
The first step is to carefully observe what tasks are being performed. When you have the opportunity to introduce a mixture or blend of natural light, via a window, into the room that is always welcome. Be careful though as you do not want to overexpose. The use or adjustment of blinds is often helpful. In general, diffuse the light by changing the blinds to reflect the light up towards the ceiling.
