Albino people lack colouring material (pigment) in their bodies.suggest why albino people should avoid looking at bright lights. [3 marks]

Probably because in bright light the colour of rods in eyes is bleached and so albino ppl, as they hve lack of pigment, wud take comparitively lot of time to reform that pigment.!!

Albino's lack pigment in their body due to a mutation in their genes. Therefore Albinos suffer hyper-photo-sensitivity. No pigment in the Choroid Layer in the eye, due to this internal reflection of light occurs. Too much of light entering the eye can damage the retina.
