Product Details
PAIR OF CATEGORY 4 REPLACEMENT LENSES FOR MODEL NATURE
The Category 4 lenses for glacier glasses are made of high-quality polycarbonate and are optically perfect. Polycarbonate is the material that makes the lenses lighter and safer. In fact, in the event of an accidental impact, polycarbonate, unlike glass, does not produce small fragments that could damage the eye. This is why polycarbonate is also commonly used in protective eyewear.
Category 4 lenses are essential for those who love the mountains. Using non-Category 4 lenses at high altitudes can lead to noticeable redness of the eyes by the end of the day, and in some cases, even tearing, necessitating a forced rest period of approximately 48 hours. In contrast, using Category 4 lenses not only protects against UV rays but also, with a darker base, allows your eyes to relax so you can simply enjoy the ride.

NATURE Category 4 Replacement Lenses for High-Altitude Conditions
Restore your NATURE glasses with a dedicated pair of Category 4 replacement lenses designed for extremely bright mountain environments. Made from lightweight, impact-resistant polycarbonate, these lenses combine a dark smoke base with a silver mirrored exterior. Category 4 filtration provides a high level of light shielding for demanding conditions such as high altitude, snow and glacier environments, helping reduce the discomfort caused by intense sunlight and strong reflections.

Replacement Lenses Designed for the NATURE Model
This product consists of a pair of replacement lenses for the NATURE model. It is intended for customers who need to replace their existing Category 4 lenses while retaining the technical characteristics of this lens configuration.
The combination of a Category 4 filter, dark smoke inner colour and silver mirrored outer surface is particularly suited to the high levels of visible light encountered in demanding mountain environments.
Compared with lighter lens categories, Category 4 lenses provide greater light attenuation. This makes them particularly relevant when prolonged exposure to intense sunlight and strong reflections from snow or ice can make vision uncomfortable.
Category 4 Lenses for Intense Mountain Light
Category 4 is the darkest commonly used sunglass filter category and is designed for environments with exceptionally intense solar radiation. For mountain use, this level of filtration is particularly useful at altitude and in areas where snow and ice can produce powerful reflected light.
The darker lens helps limit the amount of visible light reaching the eyes, supporting more comfortable vision when conditions become too intense for lighter-category lenses.
High light shielding
Category 4 filtration is designed for very bright conditions where stronger attenuation of visible light is required.
Mountain environments
Particularly relevant at high altitude and in snow or glacier environments exposed to intense sunlight.
Visual comfort
The dark smoke base helps manage excessive brightness and strong reflections during prolonged outdoor use.
Polycarbonate Replacement Lenses
Lightweight Lens Material
The NATURE Category 4 replacement lenses are made from polycarbonate, a material widely used in technical eyewear because it combines low weight with good resistance to accidental impacts.
Impact-Resistant Construction
Compared with more brittle lens materials, polycarbonate has a high resistance to fragmentation. This makes it well suited to active outdoor eyewear where low weight and durability are important.
Smoke Tint with Silver Mirror Finish
The lens has a smoke inner colour combined with a silver mirrored exterior. The dark smoke base is consistent with the high light attenuation required from a Category 4 lens, while the mirrored outer surface gives the NATURE replacement lens its distinctive technical appearance.
The mirror treatment should be understood as a surface finish separate from the Category 4 filtration itself. The primary function of the Category 4 filter is to provide strong light attenuation in extremely bright environments.
Made for Very Bright Mountain Conditions
These replacement lenses are intended for situations where light intensity can become particularly demanding, including high-altitude mountain environments and areas with snow or glaciers.
Important:
Category 4 lenses are designed for exceptionally bright conditions and
are not suitable for driving because their very dark
filtration allows substantially less visible light to reach the eyes.
