Magnification is also sometimes called the power of the binoculars â binoculars labeled as 8-power have eight times magnification. Most optics have clearly labeled magnification, usually on the large focus wheel between the two long barrels of the binns.
All binoculars will have two numbers to designate them, such as 10x50. This means a binocular with 10 times magnification and 50mm objective lenses (the big ones!). Common sizes are 8x42, 10x50, 20x60, 15x70, etc. Optical glass is generally BAK4 or BAK7 standard, BAK4 is denser and gives superior vision.
