MOUNTAIN GLASSES 2-4 PHOTOCHROMATIC LENSES FOR HIKING AND ALPINISM MODEL EIGER

 

For those who love hiking in the high mountains, they know that eye protection is a need of primary importance that cannot be neglected. The strong reverberation that occurs in high mountain areas represents a pitfall to be countered with suitable lenses to be able to enjoy the excursion in complete safety. In fact, using unsuitable lenses at the end of the day can result in continuous discomfort as if you had something in your eye or even tearing. For maximum protection and performance DEMON has created a line of mountain sunglasses with 2-4 photochromic lenses to protect the eyes in any weather and climate conditions that guarantee perfect vision.

2-4 PHOTOCHROM LENSES FOR MAXIMUM EYE PROTECTION:

The 2-4 photochromic lenses are special photochromic lenses with a smoke base color capable of reaching category 4 during maximum work. The starting color is in very light smoke color that allows correct vision even in areas with strong shadow or with very poor brightness, and in the phase of maximum work it is able to reach category 4 with the optimal light and UV conditions generally used for Mountaineering.

The 2-4 photochromic lens exposed to UV radiation and sunlight in general, initiates a reversible chemical reaction that darkens the surface of the lens until it reaches category 4 (when necessary). Once the irradiation of light and UV is over, the lens gradually returns to its original color state. Mountaineering and Hiking: This special photochromic lens has been designed with the mountains in mind and the greater intensity of UV radiation and light rays. The idea was to create a dynamic lens for hikers and mountaineers that adapts to every change of light on their path. Whether you enter a wooded area or a shady side, the lens is designed to lighten and darken quickly to allow the athlete constant and perfect vision. The starting color of the lens is a slight smoke haze that does not oblige the athlete to have to remove the glasses in areas with low light. At the same time, category 2 prevents glare for the eyes coming out of the shadow areas. Achieving category 4 during maximum work is influenced by the intensity of UV rays and light. It is important to know that this special lens is created to reach category 4 only when necessary, thus preventing too dark a view of the path. This lens can be used in place of the category 4 lens for extreme expeditions (Everest, K2 and the like) because in terms of protection it maintains the standards of category 4, but at the same time it is dynamic in light changes.
