I am colorblind and it is a serious handicap.
Before the euro, my country had two bank notes of similar color. I couldn't tell one from the other by color. One of 10 times the value of the other. On a few occasions, I received more change than expected.
I can't open an atlas and use it like you normally would. On every high school exam, the teacher had to help.
I am also a physicist and I couldn't do the spectra analysis practicum during my first year of study. I am likewise limited in the amount of colors I can use to graph data. Some data are multicolored 2D contour plots. Either I have to ask someone what the values are or make educated guesses or apply other time consuming tricks.
On the traffic lights, red is up, green is bottom. I hope they never change it/make it random or my life will be cut short.
It limits my options in life. I can never be a chemist for example.
I also feel I am missing out on some of the beauty in the world.
And so on and so on.
If someone loses a leg in an accident, do you deny him a wheel chair or prosthetic limb? Do you deny someone glasses as their eyesight deteriorates with old age? What about someone who is born deaf? Do you do deny that person the hearing aid implant?
I am colorblind and I want a cure, damnit !!!!
