View Here : The Light
Although it is environmentally friendly, blue light can affect your sleep and potentially cause disease. Until the advent of artificial lighting, the sun was the major source of lighting, and people spent their evenings in (relative) darkness.
The Light was established in December 1921 in Lahore as the English magazine of the Centre of the Lahore Ahmadiyya Movement. It had a long and illustrious history in India and then (after partition in 1947) in Pakistan. In 1990 The Light had to cease publication in Pakistan due to government measures against Ahmadiyya publications.
