Vision插件描述

Vision is software allowing people with different kinds of col blindness (colour vision deficiency) to see me cols. 

Vision provides solutions to some of the everyday problems experienced by colour blind people. People with various types of colour deficiency could benefit from the use of Vision software including those affected by Tritanopia (blue colour vision deficiency), Deuteranopia (green), Protanopia (red). 

People generally have the assumption that if you suffer from blueyellow col blindness these are the only cols you have trouble seeing. But that’s wrong. Col blindness doesn’t relate to just two col shades you can’t distinguish, it is the whole col spectrum which is affected. 

There are close to 300 million people who are colblind  struggle every day. Many of them are prohibited from becoming pilots, scientists, docts, police officers, firefighters, electricians, etc. 

It is these people that Vision is aiming to assist, by making the wld a much me colourful  better place f them.
