How "Usable by All" aims to make the World better for 16% of humanity?

In an ideal world every individual should have the right and the means to pursue: happiness, aspirations and economic prosperity, However, this is not the case as our public infrastructure and digital services have been built mainly to cater to the general public.

If we consider the user interface of a typical web application, we see that it features a low-contrast UI/UX, which makes it difficult to use for someone with advanced cataract or some other form of vision impairment. This level of difficulty which could easily have been resolved through considerate design, impacts people's lives in many ways. It makes them under-productive, prevents them from acquiring essential services at the right time, forces them to be dependent on others and undermines their aspirations.
