There is an amazing amount of science behind sunglasses and we are very proud of our efforts to distill the science into the sun protection for you. Beyond the frame style that compliments and completes your look, it’s really about the lenses. We’re passionate about styling but driven to offer the very best protection for your vision.
We make great sunglasses, the foundation of which is the lens. Polycarbonate lenses provide remarkable protection from the harmful light portion of the spectrum commonly referred to as ultraviolet rays. Although there are competitors that want you to believe their lenses are unique by giving them names from outer space or denoting mystical properties, we just offer the facts regarding eyewear that performs genuinely and sparing you the marketing hocus-pocus.
Since the introduction of our original Mela-Lens® over four years ago - Sundog Eyewear has undertaken a leadership position in sunglass lens performance. We recognized the importance of filtering the blue light portion of the spectrum in addition to dangerous ultra violet light to provide maximum protection, clarity and comfort.
Based on the patented science of Dr. James Gallas, renowned physicist and inventor, the original Mela-Lens® was formulated with Melanin, nature’s own protection from blue light. The new TrueBlue™ lens represents the evolution of Photoprotective Technologies' patented filtration of blue light.
The Science – a fascinating foundation
Light behaves like a wave which is defined by its length and frequency. We can only see light within a certain range of wavelengths and frequency. Different wavelengths are visible (seen as different colors) and invisible. Until recently, the sunglass market has been focused on the portion of the light spectrum that we don’t see as color, called ultra violet - which is a source of damage to the eye. All good quality sunglasses block ultra violet light. Of increasing concern to human vision are the wavelengths that are collectively referred to as High Energy Visible light.
There is now growing awareness about the impact of the blue light portion of the spectrum on both the front of the eye (the lens) and the back of the eye (the retina and macula). There is also medical community recognition that links blue light exposure to human vision health issues. As a result, quality lens manufacturers are starting to address the issue of blue light to varying extents.
The TrueBlue™ Advantage
The human body naturally produces melanin and ocular lens pigment; together these substances are nature’s way of defending the eye from invisible and visible light.
The TrueBlue™ lens is the only non-prescription sunglass lens in the world to incorporate both melanin and ocular lens pigment, to provide ultimate eye protection and vision performance.
