Your vision in terms of 20/x would be 20/400 for the left eye and 20/425 for the right eye. This means that from a distance of 20 feet, you can see what a person with normal vision can see from 400 feet (left eye) and 425 feet (right eye).
360,420 is the standard form of 300000 plus 60000 plus 400 plus 20.
400 + 41 = 441
100 + 400 = 500
22 + 400 = 422
