please help me..

Bad lighting is a very important issue for us all whether at work or at home. It causes constant eye strain, which can cause other issues. If you are consistently straining their eyes due to the poor lighting, you will be uncomfortable and suffer from burning, irritated, tearing, red or dry eyes. Eye strain will also cause unnecessary fatigue and stress. Vision will also suffer from eye strain. Eye strain due to poor lighting may lead to the experience of sensitivity to contrast, reduced vision sharpness, lack of vision focus, bad depth perception, and double vision.

Bad lighting can cause frequent and severe headaches. Not only will this be a health issue but it is difficult to work as well when suffering from headaches due to the distracting pain and discomfort.

Bad lighting can be a safety and health hazard in the workplace. In a business, it is necessary to be aware of the proper safety procedures for lighting. There are different kinds of bad lighting that can give problems such as glare, flicker, not enough light, too much light, contrast issues or poor placement of lighting.

Bad lighting will not only have a negative effect on employees but on a business as well. Bad lighting may cause employees to feel sluggish and tired in their work environment. The amount of work, the quality of work and the accuracy of work will all decline when the lighting is bad. If better lighting is provided for employees, they will better in productivity, accuracy and in the quality of their work.

Bad posture and awkward body poistions can be an effect of bad lighting. This can cause other health problems such as back pain, neck pain and carpal tunnel syndrome. This si because without proper lighting, it is hard to perceive the depth, closeness, shape, speed and proximity of objects and those around you. Accidents can become more frequent in areas of poor lighting.

This is a a very important point, it is essential n only at work but at home too to have the proper lighting so that if we are reading or simply watching TV or using the computer we do not strain our eyes.

At wok of course there is always the risk of an accident if lighting is not adequate and also at home older people can risk a trip or fall if they do not have good lighting over stairs etc. I must say I am not a fan of the new energy saving light bulbs, they never seem very bright to me, I can't every seem to see properly with them!

Bring back to old ones I say, I really can't get on with the new ones.
