The document explains that seeing at night requires training, as the eyes function differently: the cones (central vision, colours, details) become ineffective in the dark, whilst the rods (peripheral vision, sensitivity to low light) take over. The latter, which are 100,000 times more sensitive than the cones in bright light, require 30 minutes to adapt to darkness before reaching their full potential. Exposure to white light (even briefly) destroys this adaptation within seconds.\u003c\/p\u003e\n\u003cp\u003eKey techniques:\u003c\/p\u003e\n\u003cp\u003ePreserving adaptation: Use red goggles or red lighting (which does not affect the rods) before and during flights. Avoid all white light (matches, torches).\u003cbr\u003eLook to the side: Night vision is impossible in the centre of the eye (the cone area). To see an object, focus slightly to the side to activate the rods, which are more sensitive at the periphery.\u003cbr\u003eScan methodically: Divide the field of vision into zones and explore them one by one with short, precise eye movements (avoid random scanning).\u003cbr\u003eInterpret clues: At night, details and colours disappear. You must rely on apparent size, contrasts (e.g. the phosphorescent trails of ships, the twinkling of stars obscured by an aeroplane) and experience (recognising the typical shapes of aeroplanes or ships).\u003c\/p\u003e\n\u003cp\u003ePractical applications:\u003c\/p\u003e\n\u003cp\u003eThe crews of the Black Cat Squadrons (Pacific) followed the coastline by tracking the breaking waves or tracked enemy ships solely by their wakes.\u003cbr\u003eOn patrol, make use of moonlight: a submarine can be spotted 4 miles away when facing the moon, but only 2 miles away when with its back to it.\u003cbr\u003eTraining: Simulate night-time conditions with red-light exercises, minimise lighting in the cockpit, and memorise charts before the flight to limit the need to consult them in the air.\u003c\/p\u003e\n\u003cp\u003eChallenge: Mastering these techniques can mean the difference between a successful mission and failure, or even survival.\u003c\/p\u003e\n\u003cp\u003e18 pages – in English\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e----------------------------------\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e\u003ciframe width=\"560\" height=\"315\" src=\"https:\/\/www.youtube.com\/embed\/SzEPhfCJkRU?si=pyv6PTscUzd45073\" title=\"YouTube video player\"\u003e\u003c\/iframe\u003e\u003c\/p\u003e","brand":"US Government","offers":[{"title":"Default Title","offer_id":57162541236550,"sku":null,"price":0.0,"currency_code":"NOK","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0620\/6901\/4698\/files\/nightvisionforairmen_1.jpg?v=1787154477","url":"https:\/\/www.skyshelf.eu\/en-no\/products\/us-navy-la-vision-nocturne-des-aviateurs-1944-edition-originale","provider":"www.skyshelf.eu","version":"1.0","type":"link"}
