Which method is advisable to fix reflected glare?

1. Increase the brightness of the task

2. Move the task or light source to improve positioning

3. Use only ambient lighting

4. Maintain a fixed position for furniture

The correct answer is: Move the task or light source to improve positioning

The advisable method to fix reflected glare is to move the task or light source to improve positioning. This approach directly addresses the source of the glare by altering the angles at which light is reflected. Reflected glare typically occurs when bright light reflects off surfaces like screens, desks, or walls, causing discomfort and hindering visibility. By adjusting the position of either the light source or the object creating the glare, it is possible to minimize or eliminate the reflection altogether, therefore enhancing the visual comfort in the space. The other options do not effectively address the root cause of reflected glare. Increasing the brightness of the task could actually exacerbate the issue by adding to the contrast between the brightness of the light and the reflective surfaces. Using only ambient lighting might not provide sufficient illumination for the task at hand and can lead to inadequate visibility. Maintaining a fixed position for furniture ignores the need to adapt the layout and lighting to effectively minimize glare, which can be crucial in spaces where tasks are performed. Therefore, adjusting the position is the most practical and effective solution in managing reflected glare.
