It has been clearly shown that older people need much more light to see, although the magnitude is often under recognized. The amount of light needed for a young adult to perform a detailed task, such as reading, is 1/5 or less than what is required for an older person to perform the same task, even with excellent or corrected vision. Even less task oriented activities are more difficult as we age, such as way-finding, as evidenced by a senior remarking “They are making movies much darker these days”. In some regards, that may be true, but less so in terms of the illumination of the projection screen.
