The reason is almost always the same: dry air. In this article we explain why it happens and give practical tips for quick relief.<\/p>\n\n<h2 class=\"wp-block-heading\">Why flying and winter dry your eyes<\/h2>\n\n<p class=\"wp-block-paragraph\">Few things trigger dry eye as automatically as a long flight or central heating in winter. The common thread is dry air. When the air around you holds very little moisture, the watery part of your tears evaporates far faster than usual, leaving the surface exposed \u2013 and if your tear film is already a little fragile, that\u2019s all it takes to tip mild, occasional dryness into hours of real discomfort.<\/p>\n\n<h2 class=\"wp-block-heading\">On a plane<\/h2>\n\n<p class=\"wp-block-paragraph\">The cabin combines several drying factors:<\/p>\n\n<ul class=\"wp-block-list\">\n\n<li>Cabin air is kept extremely dry (often drier than desert air).<\/li>\n\n<li>The overhead vent blows a steady stream of air straight across your eyes.<\/li>\n\n<li>Screens and reading mean you blink far less than usual.<\/li><\/ul>\n\n<h2 class=\"wp-block-heading\">Winter is the same problem, stretched over months<\/h2>\n\n<p class=\"wp-block-paragraph\">Winter recreates the aircraft problem, just over a much longer timescale. Cold outdoor air holds little moisture, and heated indoor air holds even less, so your eyes rarely get a humid environment to recover in. It\u2019s why so many people notice their dry eye is clearly worse from late autumn through winter, with symptoms easing again in spring.<\/p>\n\n<h2 class=\"wp-block-heading\">The symptoms<\/h2>\n\n<p class=\"wp-block-paragraph\">Environmental dryness tends to produce:<\/p>\n\n<ul class=\"wp-block-list\">\n\n<li>Burning, stinging or a gritty feeling that worsens the longer you&rsquo;re exposed.<\/li>\n\n<li>Watery eyes, especially in cold wind.<\/li>\n\n<li>Tired eyes and blur that clears when you blink.<\/li>\n\n<li>Relief once you reach more humid, sheltered air.<\/li><\/ul>\n\n<h2 class=\"wp-block-heading\">How to protect your eyes<\/h2>\n\n<p class=\"wp-block-paragraph\">A little preparation makes a real difference, whether you&rsquo;re boarding a plane or facing a cold snap:<\/p>\n\n<ul class=\"wp-block-list\">\n\n<li>On a flight, redirect the overhead vent away from your face (the most effective step).<\/li>\n\n<li>Use preservative-free drops before and during exposure.<\/li>\n\n<li>Wear glasses rather than contact lenses on long flights.<\/li>\n\n<li>In winter, run a humidifier where you spend most time, and wear wraparound glasses against cold wind.<\/li>\n\n<li>Sit away from direct heat sources and car vents.<\/li><\/ul>\n\n<h2 class=\"wp-block-heading\">Frequently Asked Questions<\/h2>\n\n<h3 class=\"wp-block-heading\">Does a humidifier help with dry eyes?<\/h3>\n\n<p class=\"wp-block-paragraph\">Yes, it can markedly ease symptoms in winter and in air-conditioned rooms by raising the humidity.<\/p>\n\n<h3 class=\"wp-block-heading\">Do glasses protect better than contact lenses?<\/h3>\n\n<p class=\"wp-block-paragraph\">In dry environments often yes, as contact lenses can further promote evaporation.<\/p>\n\n\n<div class=\"wp-block-group has-background is-layout-constrained wp-container-core-group-is-layout-71818893 wp-block-group-is-layout-constrained\" style=\"border-radius:10px;background-color:#eef4f6;padding:28px\">\n\n<h3 class=\"wp-block-heading\">Find the cause of your dry eyes<\/h3>\n\n<p class=\"wp-block-paragraph\">Take the validated dry eye test or book a consultation \u2013 we will find out what is really behind your symptoms.<\/p>\n\n\n<div class=\"wp-block-buttons is-layout-flex wp-block-buttons-is-layout-flex\">\n\n<div class=\"wp-block-button\"><a class=\"wp-block-button__link wp-element-button\" href=\"https:\/\/smartdryeyes.com\/en\/dry-eye-test\/\">Start the dry eye test<\/a><\/div>\n\n<div class=\"wp-block-button is-style-outline is-style-outline--1\"><a class=\"wp-block-button__link wp-element-button\" href=\"https:\/\/smartdryeyes.com\/en\/contact\/\">Get in touch<\/a><\/div>\n<\/div>\n\n<\/div>\n\n\n\n<p class=\"wp-block-paragraph\">Prefer to be seen in person?
