CONVENTIONAL SUNGLASS LENS TECHNOLOGY
The human eye is like a camera and the retina acts as an image detector that detects light and three types of color: Blue-Violet, Yellow-Green and Red-Orange. Conventional sunglass lenses place colored filters between the image and the eye to reduce glare and ultraviolet rays. The results are limited to a reduction of light intensity with a substantially decreased sensation of color. Other lens manufacturers resort to color tinting to improve color stimulation but this type of process only improves one basic color type in the color spectrum, while decreasing sensitivity directly at the opposite end of the color spectrum
HDL-3C LENS TECHNOLOGY IMPROVES VISUAL PERFORMANCE GUARANTEED!
The patented HDL-3C decentered lens has been scientifically designed to increase visibility by equalizing the colors in the color spectrum which shortens the eye's receptors response time producing improved color sensitivity and contrast apprehension. The results are dynamic. A higher level of eye comfort, better vision and improved color sensitivity is achieved at both ends of the color spectrum with our innovative science.
The proof is in the product's performance. We are so sure that you will love the HDL-3C lens technology that we offer a '30 day no questions asked' money back guarantee. You are guaranteed these are the best sunglass lenses ever made!
HOW HDL-3 LENSES OUT PERFORM OTHER CONVENTIONAL SUNGLASS LENSES:
EUROPEAN STANDARD EN1836:
For a better comprehension of the benefits in terms of color contrast, one can examine the relative coefficients of transmittance of the colors Blue, Green, Yellow and Red. These coefficients were defined by the European Standard to provide an indication of the degree of attenuation of road sign colors as compared to the background by the effect of the filter used. Factors smaller than 1 indicates an attenuation of that specific color. Greater values than 1 indicate enhancement of the specific color and, consequently, better visibility.

Normally a smoke filter is equal or close to 1, while with other lens an increase of any of the factors is compensated by an equivalent reduction of other factors. Our smoke filter does much better as listed.
The Revolutionary HDL-3C lens equalizes the color spectrum obtaining a generalized increase of the relative transmittance factors without reduction of any color thus increasing visibility and visual performance. Only HDL-3C lenses provide increased vision in the opposite ends of the color spectrum.
