Sunglasses in winter: why you should wear them even in the cold

Occhiali da sole in inverno: perché usarli anche con il freddo

When we think of sunglasses, our minds immediately go to summer: beaches, bright sunlight, and days spent outdoors. But the truth is, sunglasses are not just a seasonal accessory—they are a protective tool for your eyes, useful and necessary all year round.

Even during the winter months, ultraviolet (UV) rays continue to affect the eyes, and in some situations they can be even more harmful. In this article, we’ll explore why it’s important to wear sunglasses in winter, the benefits they provide, and how to choose the most suitable lenses for every weather condition.

Sunlight in winter: a false friend

During winter, sunlight may seem weaker and less direct, but the intensity of UV rays does not decrease significantly. On the contrary, reflective surfaces typical of the cold season - such as snow, ice, and even wet pavements - amplify the amount of radiation reaching the eyes.

This phenomenon, known as glare, can increase eye strain and, in extreme cases, cause actual corneal irritation (the so-called “snow blindness”).

Additionally, in winter the sun is lower on the horizon, and its rays strike the eyes at a more direct angle, causing sudden glare—especially while driving or in the mountains. This is why sunglasses remain an essential ally even when temperatures drop.

The benefits of wearing sunglasses in winter

Wearing sunglasses during the cold months is not just a matter of comfort—it’s essential for complete eye health.

UV protection: Ultraviolet rays are present all year round and can damage the cornea and lens, contributing to conditions such as cataracts or actinic keratitis.
Glare reduction: Snow reflects up to 80% of sunlight, a higher value than summer sand. Polarized lenses drastically reduce this effect, improving visual comfort.
Enhanced visual contrast: Quality lenses help distinguish shapes, obstacles, and surfaces more clearly—an essential feature for winter sports enthusiasts or frequent drivers.
Protection from wind and cold: Low temperatures and dry wind can irritate the eye surface and increase the risk of dry eyes. Sunglasses act as a natural barrier, protecting tear film and eye moisture.
Prevention of periocular aging: UV radiation also contributes to skin aging around the eyes; wearing sunglasses helps preserve the skin and prevent early wrinkles.

How to choose sunglasses for winter

Not all sunglasses provide the same level of protection. During the winter months, it’s important to choose frames and lenses suited to more variable lighting conditions:

Choose lenses with UV400 protection, which block 100% of UVA and UVB rays.
Consider polarized lenses, available for men and women, ideal for reducing glare from snow, water, or reflective surfaces.
For mountain use, select lenses with category 3 or 4 filters, ensuring high protection even at high altitudes.
Opt for wraparound frames, which cover the sides of the eyes to prevent light and wind from entering.
Don’t forget style: at ILOP, we select frames that combine design, comfort, and protection, so you can stay safe even in winter… with style.

A well-chosen pair of sunglasses will accompany you not only on the snow or during vacations but also in everyday life: from city walks to driving under the low afternoon sun.

Sunglasses in winter and sports: an indispensable combination

Those who practice outdoor sports in winter - skiing, snowboarding, running, or cycling - know how reflected light and wind can impair vision. In the mountains, for example, UV radiation increases by 10–12% for every 1,000 meters of altitude.

In these conditions, polarized or photochromic lenses are the ideal solution: they reduce glare and automatically adjust to light intensity.

Even in urban settings, winter sunglasses are useful for cyclists or e-scooter riders, providing protection not only from sunlight but also from wind, cold, and dust.
