Night Vision Cost In Medicana International Istanbul

Night vision is the ability to see in low-light conditions. Whether by biological or technological means, night vision is made possible by a combination of two approaches, sufficient spectral range, and sufficient intensity range. Humans have poor night vision compared to many animals, in part because the human eye lacks a tapetum lucidum.
Night vision can be enhanced by Night vision devices, which gather existing ambient light (starlight, moonlight or infra-red light) through the front lens. The electrons are then hurled against a phosphorus screen that changes the amplified electrons back into visible light that the person sees through the eyepiece.
