Product Overview

Eyeglasses for Outdoor category 4 Polarized lenses

For those who, like DEMON, love the mountain, know that it is a real philosophy of life. However, it happens that the athlete or the simple enthusiast sometimes finds it difficult to read the tools necessary for the excursion or simply view their own path. DEMON has therefore created Outdoor, the polarized outdoor eyeglasses with polarized category 4 lenses and prescription clips on which to insert the graduated lenses through your trusted optician.

Prescription Outdoor Glasses polarized Cat4 Lenses

This new eyewear usable for all mountain sports represents a real revolution. In fact, it represents the evolution of the sports frame first for the enveloping shape that prevents light from entering laterally, then because the very wide removable clip (which allows a superior lateral view compared to common clips) allows drastically lowering the costs of graduation of the lenses and given the optical clip size, supports bifocal lenses.

Outdoor represents the category 4 polarized eyeglasses ideal for mountaineering for those who want maximum technicality for their eyes, without having to compromise.


Outdoor designed to protect your eyes even in the extreme conditions, especially in glacier areas with strong glare and in the high mountains. Used also for normal hiking, trekking and ski mountaineering, because it is essential to protect the eyes from the most intense UV rays of the mountain.


Technical characteristics and use:

Outdoor Sunglasses with category 4 Polarized OUTDOOR lenses offer protection from the intensity of UV rays, and guarantee perfect vision thanks to the top quality decentralized polycarbonate lenses.


Category 4 mountain lenses are the ultimate in technicality for those who practice high mountain hiking. They are darker than common category 3 lenses, which is why they are not suitable for driving every vehicle.


Polarized lenses offer:

»Better perception of contrast

»Clearer vision

»No modification of natural colors


Polarized lenses are very performing for mountaineering, and especially when the UV rays are more intense, they allow greater relaxation for the eyes even for very prolonged use and with very intense light conditions.


The ultra-light and elastic material of the frame is TR90, our special composition in Nylon and Carbon fiber that makes the mountain glasses 20% lighter than conventional materials, more resistant to accidental impacts and tractions, highly proofed to high and low temperatures. An essential feature during the practice of mountaineering, especially in glacier areas. This feature also contrasts very well the increase in overall weight caused by the prescription lenses used on the optical clip.


Also essential is the removable internal sponge in soft neoprene, which does not allow those annoying drops of sweat to reach your eyes, during the most delicate and most fatiguing phases of your journey.

It also does not allow light to filter through, as it adheres perfectly to the face, and in case of strong wind, it prevents the entry of snow, dust and small dirt that found along the way.


The temples are equipped with a special grip section, which serves to prevent those annoying micro-slips towards the tip of the nose, in phases of strong fatigue, vibrations or sudden movements. The nose pads and terminals are in hypoallergenic rubber, soft, super light and anti-slip, to consistently elevate the fit.

With your category 4 polarized eyeglasses for Mountaineering, the following are supplied: Internal sweatband, sight clip, elastic band and hard case, to best suit your new DEMON eyewear.

No compromises, never give up, maximum performance, always and in any case.

It is possible to mount lenses with gradations through your trusted optician: Maximum sphere +/- 8.00 and Cylinder (astigmatism) +/- 2.00.
