What about light transmission and optical coatings?

Light transmission describes the percentage of available light that passes through your binoculars. The amount of light can be increased with the use of anti-reflective coatings on binocular lenses. When an anti-reflective coating is applied to the glass surface of a binocular it increases the amount of light that reaches your eye.
     The more complete and complex the coating scheme is, the brighter and sharper the binocular image will be. Better coatings on a binocular allow more light to reach your eye, improving brightness and overall binocular performance.
