How looking through static can help people with a common degenerative disease see better

Age-related macular degeneration (AMD) is the leading cause of irreversible blindness among ageing people globally. Around one in seven Australians over the age of 50 have some signs of AMD.

The disease results in blurred and distorted vision, and often loss of function at the centre of the eye’s visual field.
