Are you color blind? Do you have a color vision deficiency.
No I am actually not I have learned through my job that it is rare you meet people with color vision.
Yes, people with it have trouble buying fruit.
Is it only fruits that is similar looking due to not being able to tell the difference in color?
No also clothes shopping and traffic lights.
I understand the lights and some shopping for clothes they would have read tags to verify the color .
Yes but not the traffic lights.Especially if you are in a foreign country.
Does the vision impairment make their sight a blur a little?
I am not sure but it is not fixable even with glasses.
I wonder if it has been looked deep into to find some kind of cure.
