There are no published guidelines on the adequacy of lighting and how to check for light adequacy without instruments. However, the Illuminating Engineer Society (IES) has recommended that for casual reading an illumination level of 100 lux is sufficient. Also the Government of India recommends up to 100 lux of illumination in living rooms.
Hence, it seems practical that if one is able to read news print in all the corners and the center of the room and also in the darkest portion of the room, the lighting can be considered adequate, provided there is no glare and the light does not directly fall in the eyes.
