3. It Can Impair Certain Careers
If you really were to sit down and think about it, the majority of careers out there don’t require you to see color as part of the job. In fact, it’s a topic that would almost never come up in casual conversation unless you made an obvious mistake such as packed shelves wrong, or putting the bananas in the wrong pile. Still, in most cases, this won’t be too much of a disaster at work and can still be counted as a minor mistake – but there are some careers where color blindness can have you excluded entirely.
If you are color blind, you are unable to pass the vision tests for being a firefighter or police officer, for example: Here, shades and colors could mean the difference between life or death in an emergency situation.
This is one part of why vision tests are part of applying for the job.
