HDL-3C Stands For…

• Improved Color:
  The HDL-3C lens equalizes the colors in the color spectrum, producing improved color sensitivity and contrast apprehension. A unique aspect of HDL-3C technology is that it really brings out the colors you see, without artificially tinting everything else in order to do so. Reds and oranges become incredibly vivid and blues become deeper… it’s almost like turning up the contrast control on the world around you! It’s an amazing effect that you just don’t see with any other sunglasses.

• Improved Clarity:
  The HDL-3C lens is a decentered lens designed to increase visibility and eliminate distortion. The HDL-3C lens technology costs more to make (5 to 15 times more than the other high-end polycarbonate lenses on the market) but these lenses are truly the finest optics available anywhere. We feel it’s well worth the price, and believe that once you try a pair on, you’ll agree.

• Improved Comfort:
  The HDL-3C lens technology achieves these dynamic results without stressing the physiological vision system… they can be worn all day long without any eye strain. The polycarbonate lenses are not only the best material optically, but are also very lightweight and impact-resistant. Most VedaloHD styles feature a hingeless design and rimless frames, providing physical comfort, maximum coverage, and no frame interference. Titanium models are the ultimate in light weight… they only weigh 12 grams! This is the ultimate design for headset comfort. Flying is demanding enough without being distracted by uncomfortable sunglasses!

• Improved Acuity:
  ‘Visual acuity’ is defined as the capability of the eye to discriminate between very small objects or objects that are very close together, and depends on the difference of luminance and chromatic contrast of the filter and objects viewed. Higher visual acuity means the person will have better visual performance and safety in activities requiring fast visual response, such as flying. Increased visibility of certain colors, combined with the correct light transmittance, results in enhanced visual acuity. This is particularly important for flying when you need the maximum perception of moving objects, cloud formations, other aircraft, ground landmarks, and runways, as well as the ability to read maps and instrumentation. HDL-3C filters reduce the amount of light reaching the eye in order to reduce glare (like nearly all sunglasses) but they’re unique in their ability to improve both color and color contrast throughout the spectrum. This improves visual performance.

Other Important Features:

• Choice of Tints:
  We have three lens tints to choose from, all of which use the same great HDL-3C technology to achieve stunning visual performance… you can choose the one that best matches your particular usage.

• Great Looks:
  Nobody wants to wear ugly sunglasses, no matter how good the lenses are. VedaloHD frames feature the best in fashion and high-quality workmanship, in a variety of styles.

• Durability:
  The best scratch-resistant coating has been applied to protect the lenses. Please use the free micro-fiber sleeve provided with all our glasses to clean lenses so as not to rub off coatings with an abrasive cloth.

• UV Protection:
  Never wear sunglasses with less than 100% protection from ultraviolet rays, which cause cataracts and other eye damage. All VedaloHD HDL-3C sunglasses provide complete UV protection up to 440nm. They are blue light and infrared effective and exceed all American, Australian, and European optical standards (including traffic light standards).

• Accessories:
  All VedaloHD HDL-3C sunglasses come with a free hard case to protect your investment, as well as a free Micro-Fiber sleeve that not only provides additional protection but acts as the best cloth for cleaning your VedaloHD sunglasses. Please don’t use any other cloths as they are more abrasive.

• Satisfaction Guaranteed:
  If you don’t agree that these are the best lenses you have ever owned, return them within 30 days for a full refund — no questions asked! Please be sure to give them a few days on your face… the increased visual performance these lenses offer is nothing like your eyes have experienced before, so some folks find it takes a little getting used to at first. We’re sure that it won’t take long before you won’t want to wear anything else! VedaloHD stands firmly behind the quality of their craftsmanship. If you have a quality issue with a VedaloHD or ColorEyes product, they will fix or replace your sunglasses for a year!
