Sydney may be propping up the ladder after six rounds, but you can't accuse the Swans of not trying new things to fix their form slump.

Tuesday's training session at the SCG saw a number of players running around wearing what looked like sunglasses.

It turned out they were stroboscopic glasses, designed to help with perceptual cognitive training.

The glasses reduce vision and train the brain to work with fewer visual cues.

NBA star Steph Curry used the glasses late last year to help work himself out of a form slump and improve his shooting percentage.

"The two things it is trying to train are ball-handling and vision," Sydney Swans Football Operations Manager Peter Berbakov told The Daily Telegraph.

"By restricting the vision and information you are able to process, it makes you focus on what the relevant cues are."

"The aim is to process things quicker and being able to handle with the same level of skill."
