TECH SPECS
The patented HDL-3C™ lens technology was designed specifically for the Aviation Industry. This new science was developed to improve visual acuity and increase safety in the cockpit environment. By examining what visual acuity means to pilots and by analyzing a FAA safety report (DOT/FAA/AM-30/6) on Sunlight's association to aviation accidents, we can identify the reason the HDL-3C™ lens was developed to aid pilot's in the cockpit.
Visual Acuity
Visual acuity is the capability of the eye to discriminate between very small and very close objects. Higher visual acuity means better visual performance and safety in those activities requiring fast visual response. Visual acuity depends on the difference of luminance and chromatic contrast of the filter and objects viewed. An increased visibility of certain colors combined with the correct light transmittance results in enhanced visual acuity. This is particularly effective when flying; as it improves the perception of moving objects, cloud formations, other aircraft, ground landmarks, airport runways, as well as aiding in reading maps and all instrumentation. HDL-3C™ filters reduce the light reaching the eye in order to reduce glare but they also improve the color and color contrast throughout the color spectrum that improves visual performance.
"Glare from natural sunlight can be visually debilitating and lead to operational error that can result in mishaps. In some cases, use of appropriate sunglasses would have minimized the affects of glare on vision performance. However, when using sunglasses there should be a proper balance between visibility of objects inside and outside of the cockpit environment." The FAA states that proper sunglasses should:
-
Include lenses "that are free from distortions and imperfections." The HDL-3C™ lens is the highest quality lens on the market. Intercast Europe is the world leader in crafting the finest optical lenses and they produce the HDL-3C™ lens in Italy. The HDL-3C™ lens costs 6 to 15 times more to produce than other high-end conventional sunglass lenses due to the innovative science built directly into the lens itself and the quality optics of this lens. This lens is also de-centered which eliminates distortion found in other lenses.
-
Use lenses that "have adequate transmissivity (approx 15% transmission)." The HDL-3C™ lens block glare and allows pilots ample light transmission due to the increased chromatic contrast our new science provides. Because of the increase in visual acuity with this patented technology discussed above, we offer more ability to cut glare (less transmittance) while allowing the eyes to see better than many lenses that let in much more light. Our Copper-Rose HDL-3C™ lens has a 13 % light transmittance yet it is fantastic to wear inside the cloud deck while reading all instrumentation (no need to flip up anymore!). Our smoke lens has a 12% light transmittance yet allows pilots to read all instruments in sunlight.
-
Use lenses that "do not that do not alter color perception (e.g., neutral gray)." This is exactly what the HDL-3C™ lens technology is all about! ALL other conventional lenses resort to tinting of their lenses to achieve an enhancement of one of the colors in the color spectrum that directly results in the reduction of color sensitivity on the other side of the color spectrum! An example (complete chart in Data & Facts) of this is the leading aviation brown-copper lens that gives our eyes a coefficient of 1.42 in the red spectrum (1= naked eye and anything above that gives better visibility and visa versa) but has a coefficient in the green of .83 and of .85 in the blue. The FAA recommends the conventional premium gray lens for they have a more even coefficient with .98 in red, 1.04 in green and 1.26 in blue. The innovative HDL-3C™ lens allows all color sensitivity to improve with a coefficient of 1.54 in red, 1.04 in green and 1.59 in blue! Yes, like a plasma high definition for your eyes!
-
"The use of larger lens sizes and wrap-around frames can prevent sunlight from entering peripherally and affecting the pilot's vision." We are proud that all COLOREYES™ sunglasses offer an 8 base design which means they all offer the most complete wrap around protection available on the market. We also offer many large aviator styles such as the Argento and Duello styles that offer the maximum coverage and are best for looking down to read your instrumentation.
-
"The use of polarized sunglasses should be discouraged, since they can reduce or effectively eliminate the visibility of instruments that incorporate anti-glare filters or can interfere with visibility through an aircraft windscreen due to striations in some laminated materials (39). Polaroid sunglasses can also mask the sparkle of light that reflects off shiny surfaces, such as another aircraft's wings, fuselage, or windscreen, which could reduce a pilot's reaction time in a "see and avoid" traffic situation. The HDL-3C™ lens is non-polarized for it was designed for the best performance optics available for pilots. Try on a pair- we guarantee you will love them and our proof is in the product's performance!
OTHER INFO and FEEDBACK
MAIN FEATURES OF HIGH DEFINITION LENSES BY COLOREYES™:
Patented HDL-3C™ Technology: Through tri-stimulus color contrast techniques; this scientifically advanced lens improves the eye's capability to discriminate colors while emphasizing the chromatic differences in the visible spectrum and providing 100% UV protection (UV 400).
HDL-3C™ stand for: HIGH DEFINITION LENS improving COLOR, CLARITY, COMFORT:
Improved Color: The HDL-3C™ lens has a filter built directly into it which equalizes the colors in the color spectrum increasing the eye's receptors response time producing improved color sensitivity and contrast apprehension.
