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.
Full size binoculars have objective lens sizes of 40mm and larger. The objective lens is the one furthest from your eye. Because of the larger size, they can capture more light and will offer a fine image in low-light situations. Full-size binoculars also offer steadier images and with a wider field of view, are a great choice for wildlife viewing.
