IMPACTX lenses
ImpactX® lenses are unbreakable (thanks to their unique semi-rigid structure) and self-tinting (lightening) depending on weather conditions, making them ideal for changing light conditions. These lenses were originally developed for military and aviation applications to be ultra-lightweight, bulletproof, and transparent, providing significantly better protection and reliability compared to polycarbonate or polyamide lenses. The semi-rigid structure of ImpactX® lenses ensures optimal physical protection for the eyes against external impacts while minimizing the severity of injuries that may result from falls or blows. 

ImpactX® photochromic lenses features

• Darkens in seconds according to light intensity
• Guaranteed lifetime shatter resistance + best protection for your eyes against injury
• Excellent scratch resistance
• Exceptional image quality that improves visibility and reduces eye fatigue
• Protects against harmful UV radiation

When choosing glasses, consider how well the lenses are suited to the main area of use (e.g., sport) and environment. (photochromic) Impactx 2 lenses:
LE 73 Impactx photochromic 2 black (filter category 1->3; light transmission 74% – 9%).

FOTONYK glasses are lightweight (253g – 275g depending on the presence of protective rubber pads) and durable. They have exceptionally comfortable and easily adjustable nose pads, which means that these glasses can be adjusted to suit any face shape. The nose pads can also be used to adjust the height and distance of the lenses from the face. The extremely simple lens replacement system allows you to quickly replace one pair of lenses with another when weather conditions change. Fotonyk glasses have a special easy-to-open and close air vent that ensures better air circulation and visual performance and helps prevent the lenses from fogging up.

Fotonyk glasses come with lens protectors (bumpers) that can be replaced and removed if desired. They are made of soft and durable polymer and provide additional protection for the face in case of a fall or collision. If desired, protective bumpers in different colors can be purchased to make the glasses even more personalized.
