They are "low light" or "day & night" binoculars that use red or orange multicoated films to enhance light transmission in dim conditions. They cannot see in total darkness.Optics: Most feature a "red membrane" or "ruby coating," which helps reduce glare in bright daylight but can sometimes cause a slight color cast
