The short answer: Yes. UV does not take the winter off, and snow reflects up to about 80 percent of it back at your eyes, roughly doubling your exposure. The low winter sun sits right in your sightline, and glare off snow and ice is intense. Winter sunglasses with UV400 protect your eyes and cut that glare, on the slopes and on the drive.
UV is year-round
Ultraviolet light reaches you every season, through cloud and cold alike. Your eyes need the same UV400 protection in January as in July; see UV protection and your eyes. Skipping sunglasses in winter because it is not hot is a common mistake, since temperature has nothing to do with UV.
Snow makes it worse
Fresh snow is a near-mirror for ultraviolet light, reflecting a large share of it upward into your eyes. That is why UV exposure on a bright snow day can rival or beat a summer beach. It also causes photokeratitis, a painful sunburn of the cornea sometimes called snow blindness, after intense reflected UV with no protection. High altitude adds even more UV. This is a real reason skiers and winter walkers wear eye protection.
The low winter sun and glare
In winter the sun sits low on the horizon, so it shines almost straight into your eyes for much of the day, on the drive to work and on a walk. Glare off snow, wet roads, and ice is harsh. Polarized lenses cut that surface glare well for driving and everyday winter use, though some skiers prefer non-polarized on icy slopes to keep the sheen that warns of slick patches; see polarized vs non-polarized.
What to look for in winter
Choose UV400 first, always. A close or wrap fit blocks wind and reflected light from the sides, which also helps eyes that water in the cold; see why eyes water in wind and sun. For bright snow, a darker category or a mirror coating cuts the glare. For flat, overcast light, an amber or rose tint lifts contrast. Match the lens to the day.
From our test bench. We meter UV on a bright snow day and the reading climbs sharply compared with the same light over grass, because the snow throws UV back up at the eyes. The pairs that helped most had UV400, a close fit, and a darker or mirrored lens. Winter is not a season to leave your eyes uncovered.
FAQ
Do you really need sunglasses in winter?
Yes. UV is year-round, snow reflects a large share of it back at your eyes, and the low winter sun and glare are intense. UV400 sunglasses protect your eyes and cut the glare.
Is snow glare bad for your eyes?
It can be. Fresh snow reflects most UV upward, and intense reflected UV without protection can cause photokeratitis, a painful corneal sunburn known as snow blindness. UV400 sunglasses or goggles prevent it.
What sunglasses are best for winter and snow?
UV400 lenses with a close or wrap fit. A darker or mirrored lens cuts bright snow glare, while amber or rose lifts contrast in flat light. Skiers on ice sometimes prefer non-polarized.
