The two numbers are a ratio, known as the Snellen Ratio. The bottom number is the distance someone with normal vision can distinguish a reference. The top number is the distance the person being tested can distinguish that same reference. Therefore, 30/30 is the same as 20/20 (the usual way of saying someone has normal vision).
30 50 is considered mild vision loss, or near-normal vision.
30/30
25-30 v = -5
