A famous study on vision, conducted in 1933, presented a phenomenon known as the "Stiles-Crawford effect of the first kind" which says that the percentage P of the total luminance entering a pupil of radius milimetres that is sensed at the retina is given by P(r) = 1-10-2 T2 In 10 Find lim P(r). +0+-* A famous study on vision, conducted in 1933, presented a phenomenon known as the "Stiles-Crawford effect of the first kind" which says that the percentage P of the total luminance entering a pupil of radius milimetres that is sensed at the retina is given by P(r) = 1-10-2 T2 In 10 Find lim P(r). +0+-*
