20/20 Vision

Having 20/20 vision isn't the same thing as having "perfect" vision. * Meaning you can read at 20 feet a symbol/letter that most human beings should be able to read at 20 feet.”. If you can see further than this, you have better than 20/20 vision, and this is very common.

Tetrachromatic Vision

Some women can have a genetic mutation, which causes them to see millions more colours. ** It’s a phenomenon known as tetrachromatic vision that allows around 2% of women to perceive 100 million colours instead of 1 million like most people.
