How to read lens numbers (10x42):
The first number (10) is the magnification power, which means this particular model will make the object look 10 times closer than the unassisted eye.
The second number (42) 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.
