The Premier League have employed eye doctor Sherylle Calder to help referees see incidents more clearly, ?the Sun have reported.
The South African has worked with Rugby Union officials, and was described by England coach Eddie Jones as the "X factor".
She said: -We work on many things, including making effective decisions under pressure — and that’s exactly what these guys are doing on a consistent basis. It’s tough work. They have to be able to see correctly and make sure their decision is effective. With the linesmen, that offside call is so critical and you have to see it so quickly. That’s exactly what we’re training with those guys.
Six top referees and four assistants will be trained with an advanced version of her ‘EyeGym’ training programme.
