Mountain sunglasses

In the mountains, light does not behave as it does in the lowlands. Reflection off light-colored rock, snow, or a névé in midsummer multiplies UV exposure, far beyond what the eye can comfortably tolerate without suitable protection. Lagoped mountain sunglasses are designed specifically for this use, manufactured and assembled in France, with frames made from recycled plastic sourced from industrial offcuts and upcycled polycarbonate lenses.

Three models for three levels of exposure

The range is built around three pairs of sunglasses, each suited to a different level of light intensity. The LAGOPEYE CAT3 is designed for everyday mountain use: hiking, climbing, and day trips where the light remains strong without becoming extreme. The LAGOPEYE CAT3POLA adds a polarized treatment that significantly reduces horizontal reflections, providing real comfort beside a high-altitude lake or on a névé that catches the light. The LAGOPEYE CAT4, with category 4 lenses, is reserved for the most intense exposure: high mountains, glaciers, and ski touring in full sun, where category 3 is no longer enough to protect the eyes from radiation reflected by the snow.

Verified French manufacturing, from recycled plastic to final assembly

All three LAGOPEYE models are manufactured and assembled in France, a feature specific to this accessory range compared with the rest of Lagoped’s clothing line, whose production is spread across several European Union countries. The frames are made from recycled plastic sourced from industrial offcuts, with color integrated into the material rather than applied as a surface coating, which improves their durability over time against UV rays and friction. The lenses, made from upcycled polycarbonate sourced from French production leftovers, provide clear vision without color distortion, a point often overlooked in low-end sunglasses.

The screwless construction is another technical feature of the range: it extends the frame’s lifespan and makes recycling easier at the end of its life. The removable sun shield, included with all three models, adds extra side protection whenever light intensity warrants it, without being essential for everyday use.

UV protection designed for the terrain’s actual intensity

All LAGOPEYE lenses filter all three types of UV radiation—UVA, UVB, and UVC—regardless of the category selected. The difference between the models therefore lies not in their UV protection itself, but in the amount of visible light they filter and the visual comfort they provide in specific conditions. A hiker alternating between wooded trails and open ridgelines will find CAT3 to be a versatile compromise, while a mountaineer traveling across a glacier needs CAT4 to avoid glare and eye fatigue caused by prolonged exposure.

Complete your sun protection in the mountains

Sunglasses cover only part of the face exposed to the sun at altitude. For complete protection, explore the clothing made from UPF 50+ certified fabrics, which protects the rest of the body from UV radiation, as well as the full hiking clothing collection for outfitting a mountain trip from head to toe.

Frequently asked questions about mountain sunglasses

Which category of sunglasses should you choose for the mountains?

The choice depends on the light intensity encountered in the terrain. Category 3 is suitable for most mountain outings—hiking, climbing, and walks at moderate altitude—with sufficient visible-light filtering for versatile use. Category 4 becomes necessary above 3,000 meters or on glaciers, when reflection from snow and ice multiplies the light intensity perceived by the eye. The LAGOPEYE CAT3 and CAT4 sunglasses meet these two needs, manufactured in France with upcycled polycarbonate lenses that protect against UVA, UVB, and UVC.

Are polarized sunglasses necessary for high-altitude mountains?

Polarization is not systematically recommended in high-altitude mountains: it effectively reduces horizontal reflections from water or wet surfaces, but it can hide certain contrasts that are useful for spotting a patch of ice or a fragile area on a glacier. For versatile use that includes outings beside high-altitude lakes or on névés, the LAGOPEYE CAT3POLA provides genuine visual comfort. For exclusively high-mountain use, where accurately reading the terrain is the priority, a non-polarized model such as the LAGOPEYE CAT4 is often preferable.
