night blindness is particularly caused by deficiency of vitamin A (retinol)
Our eyes contain 2 photosensitive cells
- rods-for scotopic vision i.e., for night vision contain pigment rodopsin
- cones-for photopic vision i.e, to see colours in presence of light contain pigment ionopsin
rodopsin pigment contain retinal, an aldehyde of retinol(vitamin A)
Therefore deficiency of vitamin A effects scotopic vision and is known as night blindness
