Blindness

  • Ashley Firth

摘要

According to the World Health Organization, 40 million people worldwide are registered as Blind.1 Add to this the rise in age-related disorders like glaucoma and diabetes in aging populations around the globe, and you have a staggering number of people who will need to access content online in a different way. This use of the Web creates a specific set of access needs, as blind and visually impaired users must be able to access the Internet without visual information.
