The Science of Tear Production in Flight Airplane cabins create a uniquely challenging environment for eye health. At cruising altitude, humidity levels plummet to 10-20% – drier than most deserts. The human tear film evaporates 2-3 times faster in these conditions, triggering reflex tearing as the eye's emergency [...] Read more
