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.

Sunday's clash on the Swans home ground against the Brisbane Lions will be the first chance to see if they've delivered any benefit to John Longmire's men.
