Abstract

Centuries back all work was done during daytime and night was utilized mainly for rest. In modern times with the development of electric gadgets little difference is left between day and night. Nevertheless, in developing countries and more so in rural areas still electric filament bulbs are the commonest source of illumination. Even in daytime electric bulbs are needed for indoor work. However, the use of these bulbs has been mainly empirical by common sense as knowledge about illumination is rather primitive even in cities and in educated persons also.
Continued use of improper illumination is a very common cause of eye strain which may lead to great discomfort and even organic disease. Students who form a large bulk of population suffer the most as they have to read for long hours. In the present work an effort has been made to measure the illumination emitted by different type of bulbs by a luxmeter at different distances. Theoretical requirement of illumination is available from books but hardly anyone knows how to get that illumination by electric bulbs. Even an approximate required illumination for different types of work has been worked out. If this guideline is followed many persons suffering from eye strain can be relieved without any medicine. The efficiency of work will also increase.
