PRESCRIPTION SPORTS GLASSES WITH PHOTOCHROMIC LENSES

For all athletes who practice disciplines with frequent light changes or simply chose the photochromic lens as a companion of adventures to practice their favorite sporting activity, many eyewear manufacturers have created sports glasses with photochromic lenses. The real problem arises when the athlete uses prescription lenses to practice his favorite sport.

DEMON has therefore created a special line of prescription sports glasses with photochromic lenses.

The eyewear looks like a normal pair of glasses with an open frame below, but on the inside, we find a removable clip attached to the frame in which the lenses will be applied.

The vision clip represents the economic and at the same time high-performance solution for those who want a prescription sports glass with photochromic lenses without the high cost of the graduation of the main lens typical of curved sports frames generally in base 8.
The optical clip of the prescription sport glasses with photochromic lenses it is located behind the main curved lens, this allows to maintain the photochromic characteristic of the glasses seen sport and at the same time use graduated lenses for perfect vision.

Technical characteristics of prescription sport glasses with photochromic lenses:

• Photochromic Lenses:  These are special lenses which, when exposed to UV radiation or to sunlight in general, generate a reversible chemical reaction which leads to their darkening. Once the radiation of light disappears, or enters closed environments, the lenses gradually return to the initial state of transparency. The convenience of this type of lens has endorsed the need to make weather forecasts before dedicating yourself to your outdoor activity and deciding which pairs of lenses to wear in case of rapid changes. These lenses are particularly appreciated for those who practice MTB. The predilection of athletes who in their own path are faced with various areas of Light / Dark, Wood / Light is to use photochromic lenses, among these who practice Mountain Bike and Trail Running. They can also be used for training, marathons, ultramarathons and disciplines that involve a very prolonged use in sunlight. They can also be used for sailing and for flight as a paraglider.
  There are 3 types of photochromic lenses present in the line of sight sport glasses with photochromic lenses:

• Photochromic 2-4 Lenses: This special lens has a similar starting color (a shade of darkness more) than the photochromic lens DCHROM and under maximum work can re achieve category 4. It ‘photochromic lens best performing currently on the market for those who practice hiking and mountain climbing. In fact, it offers a significantly greater protection to extreme light conditions typical of high mountains compared to other lenses more suitable for other types of sport.

• DCHROM Photochromic Lenses: they have a slightly darker base starting color than the other smoke photochromic lenses and reach category 3 during maximum work. In addition to the remarkable speed of clear dark change, they will surprise you for the remarkable sense of relaxation that they can provide your eyes, even on days with very strong solar radiation.

• Photochromic Smoke Lenses: they have a completely transparent base color and in the maximum work phase they reach 2.5 category. These lenses are particularly recommended for those who use glasses even indoors as a simple protection, for those who use glasses for night excursions and at the same time make a daily use in the hours of sunshine.

• Unbreakable lenses: The photochromic lenses mounted on prescription sports glasses are made of top-quality polycarbonate. Polycarbonate is lighter than using conventional materials. It also has un breakability as a key feature. Using sport-sight glasses with unbreakable photochromic lenses is a safety you can’t do without. The lens in the event of a very strong impact distributes the shock throughout its surface preventing the creation of small fragments that could damage the eye.
• Removable Optical Clip: The optical clip is the special view holder on which to apply the corrective lenses through your trusted optician. The clip can be removed at will, in fact the glasses can be used as normal glasses even without using the clip, if you intend to practice your discipline using contact lenses.
• Ultralight frame: All sport sight glasses with photochromic lenses are made of TR90, a special composition of Nylon and Carbon Fiber which makes the glasses 20% lighter than frames made with conventional materials. It also makes the glasses more resistant to high and low temperatures, more elastic and more durable over time. The TR90 is an-allergic material, like the GRIP rubber parts in soft Megol. The rubber parts, besides giving stability to the glasses, help to counteract all the vibrations and micro movements generated by sudden changes of direction.
