Too much lighting can result in glare. Measures to prevent low or excessive levels of lighting, glare or reflection include: providing additional lighting, such as a lamp on a movable arm changing the position of existing lights changing the location of the workstation increasing or decreasing the number of lights changing the type of lighting used e.g. from white light to blue light changing the diffusers or reflectors on existing lights using screens, visors, shields, hoods, curtains, blinds or external louvers to reduce reflections, shadows and glare.
