How to read lens numbers (8x21):

The first number (8) is the magnification power, which means this particular model will make the object look 8 times closer than the unassisted eye.

The second number (21) is the front objective lens, which determine how much light it can transmit - the larger this number, the better it performs in low-light conditions.
