we at DEMON we thought we'd create a mini guide to help you shed some light on the type of glasses Outdoor that's right for you.

glasses from outdoor for hiking and mountaineering

Regardless of whether the cycling glasses are chosen for practising Alpinism o Hiking it is essential to choose the frame based on the following criteria: 

  1. ENVELOPING: The frame for mountain glasses differs in primis for the envelopment, which in addition to the role of comfort for the most difficult passages, serves to protect the eyes as well as from the air, from possible external projections, such as: dust, leaves, branches and insects.
  2. LIGHT AND ELASTIC: Fundamental role, given the prolonged use of mountain glasses are: lightness and elasticity. Glasses that you don't realize you're wearing are good glasses. All frames DEMON  are created in TR90, one specialand compositionsone of Nylon and carbon fiber which makes the cycling glasses 20% lighter than conventional materials, significantly increases elasticity and makes the glasses non-deformable at high and low temperatures. Elasticity is important for the fit, in fact the glasses have the task of wrapping the face, without tightening and becoming annoying.
  3.  DIMENSIONSONE OF AUCTIONS:  The sizeone of the auctions, in addition to the aesthetic factor, performs functionsone of protectionsone further. It's a plus to the enveloping factor. In particular, when hiking, the use of wider temples is particularly preferred for greater protectionone from leaves and branches in the zone very dense forests, or particular passages where you come into contact with particular obstacles.
  4. SWEAT FOAM: This particular accessory supplied is particularly appreciated by those who practice mountaineeringone with some technical mountain glasses for mountaineering from the collectionone, not only has the role of preventing annoying drops of sweat from reaching the eyes, but also prevents light from entering from the side. Specialmind at very high altitudes where UV is more intense.
  5. ELASTIC CORD: Many mountain glasses from the collectionone they are equipped with an adjustable and removable elastic cord in the package. This particular accessory can be very useful in case of complicated passages during the journey, or simply to have a better grip on the glasses and avoid annoying micro slips towards the tip of the nose. If you use mountain glasses for ski mountaineering, the elastic cord can be very useful during the descent.

It is fundamental to start from the assumption that regardless of the discipline practiced, Mountaineering or Hiking, the lens of the cycling glasses must be: ANTI-BREAKAGE and OPTICALLY PERFECT.​ Because your glasses, in addition to protecting your eyes from sunlight and UV rays, MUST provide maximum protectionone even in the event of accidental impacts. The factor Anti-breakage it ensures that the lens does not break in the event of very strong impacts, thus not creating any splinters, which could damage your eye, but rather creates a "cobweb effect" which simply invalidates the lens. Optically perfect, consists in seeing a point exactly where it is located, to have perfect perceptionone of depth.

There are different types of lenses, below we will explain the main characteristics and for which discipline they are most similar:

  • PHOTOCHROMIC LENSES 2-4: Photochromic lenses are lenses that, when exposed to UV radiation or sunlight in general, start a reactionone reversible chemistry and darken. Once you irradiate itone of light disappears, the lenses gradually return to their initial state of transparency. They can be used both for mountaineering and hiking, so it is important to point out that the lens darkens and reaches category 4 only when necessary. If your outing is at lower altitudes the lens will darken until it reaches Category 3. However, if the altitudes start to be high or on a glacier where the UV is more intense, the lens will reach Category 4 of darkness, providing best protection your eyes, even with prolonged use in very intense light conditions.

  • LENSES Category 4: Recommended for hiking and mountaineering. They are very dark lenses, often used on glaciers. You get the most out of these lenses in zone of strong brightness and UV intensity. These lenses are generally equipped with anti-fog treatment, their peculiarity is that they are darker than the normal Category 3, and on very intense sunny days, particularly on summer days, they allow you to always keep your eyes relaxed, even with very intense solar and UV conditions.

Below is an example of Category 4 lenses:

  • LENS DPOL:  The polarized lens guarantees protectionone from UV rays, but not only: this specialand type of lens, in fact, is able to concentrate or diverge the rays of light and attenuate radiation UV-A and UV-B via a polarizing filter that eliminates transverse reflections. 

The advantages of polarized lenses are:

  1. Better you perceiveone of the contrast
  2. Visionone clearer
  3. No modification of natural colors
  4. Eliminatione of transverse reflections

This type of lens for mountain glasses is recommended for those who practice hiking, while it is less idonea for mountaineering as it may be too light at very high altitudes and with very intense UV and light. For normal excursionsone instead, grazie to the perfect perceptionone of natural colors, will make you see the mountain with new eyes.

  • CATEGORY 3 SMOKE LENS: It is the same Fumo lens fitted as standard in sports glasses. This lens is especially recommended for Hiking use on sunny days. This type of lens is often chosen for those looking for multipurpose glasses that can be used in combination with other disciplines, such as running. This type of lens allows you to spend a little less than more complete lens packages, but which you don't need.

Below is an example of Smoke Category 3 lens

  • What is the main advantage of choosing a 2-4 photochromic lens or a Category 4 lens?  The smoke photochromic lens is mainly suitable for those who are passionate about itineraries with large zone forested with low light, looking for glasses from performance advanced, which can be used for both Alpinism e Ski touring, which for a normal output of Trekking. While the Category 4 lens is more suitable for the practice ofAlpinism pure, for very prolonged use with very intense light conditions.
  • Do you suffer particularly from light? If your choice is for a photochromic lens, definitely the Photochromic 2-4 lens. If, however, you are oriented towards a dark lens, the Category 4 lens is for you.
  • Do you travel routes with strong brightness?  (fairly high altitudes, desert, ....) Our advice is the same for those who particularly suffer from light to avoid minor irritations to the eye due to not having adequately protected themselves: If your choice is oriented towards a photochromic lens, definitely the Photochromic 2-4 lens. If, however, you are oriented towards a dark lens, the Category 4 lens is what you are looking for.
  • Do you have a habit of hiking early in the morning or at the end of the day? In this case we suggest that if you are oriented towards a photochromic lens we confirm that it can be a solutionone very interesting. because it will adapt as you increase or decreaseone of solar intensity.
