audio.  
1.2.7 Extended Audio

  • Around 2% of the population has some kind of vision disability (i.e. are blind or have significant difficulty seeing even with glasses)
  • Around 50% of the population has some kind of clinically significant refractive error (a visual impairment which may be corrected with glasses if mild enough)
  • Around 8% of males and 0.5% of females have some form of color vision deficiency
  • Around 2% of adults have a hearing disability
  • Over 4% have a cognitive disability (difficulty remembering, concentrating, or making decisions) [3]
