Yes. The sight screen has a lot of relevance.
The sight screen helps the batsman to spot the ball better. In One Day
Internationals and Twenty20 cricket matches, the sight screen is black
in colour as the ball used is white colour. In Test matches, the sight
screen is usually white in colour as the ball used is red in colour.
A standard cricket pitch is 22 yards which is approximately 20 meters in length.
The ball would reach the other end of the pitch in about 0.5 seconds. Within this short amount of time, the batsman ideally should be focusing on the shot selection, placement and the power he is to give on the shot. He cannot afford to play 'spot the ball' with the bowler as it could result in him missing the ball or worse getting hit and eventually injured.
