Answer 1

We close our eyes when large amount of Light falls on it. This is because the presence of rod cells and cone cells in the eyes. Which controls the passage of Light through our eyes and if large amount of light falls on our eyes,the condition may come we became Blind.

Rod cells are also called as Photoreceptor cells and it controls the amount of light in less visibility while Cone cells controls the amount of light in High visibility.
