This review is for the Revant Optics HC3 Elite Holbrook Replacement Lenses. Revant's "HC3 Elite" lenses, seem like a competitor to Oakley's new "Prizm" lenses, but we'll talk more about that later. Check out my Frogskins review here: Revant Optics Frogskins Polarized Lens Review | Oakley Forum Full Disclosure: I was in need of some replacement lenses for my Frogskins and looked at Revant Optics. Revant Optics was nice enough to send us these HC3 Elite lenses free since they were eager for us to try them, despite me telling them I would be brutally honest. Kudos to them for having confidence in their products, and a brave marketing team. Here is the link to the lenses in this review, and a shot of all the lenses when they arrived: Polarized HC3™ Stealth Black Replacement Lenses for Oakley Holbrook | Free Shipping, Revant Optics As I mentioned in my other review, these lenses came in a Revant Microfiber bag, which is pretty similar to the ones Oakleys come in. First impression of the elite lenses, out of the box, was that they seemed no different than anything else. Basic black lenses, though I do prefer an Iridium or "MirrorShield" coating as Revant calls it, which is a reflective coat on the lenses. Just a personal preference, but I would like to see that in the future on these lenses. For this review, I used my Clear/Chrome Iridium Holbrooks. After unboxing the lenses, I popped them in to see what all the hype was about. The fit was perfect, pretty much the same as the original Oakley lenses. The lenses look very dark as they are the "Stealth Black" color, though I still would prefer a mirror coating (Fine, I'll let it go ) Revant describes their "Elite HC3" lenses on their site as: " HC3™ lens technology enhances your vision with high clarity, comfort and contrast to reduce eyestrain and allow you to see the world in vivid accuracy." Finally after popping them in, I went for a stroll outside. At first in the daylight, I noticed no difference. To me it seemed like normal Black lenses. Then, I switched back to my standard lenses, and BAM! I noticed a huge difference. Especially in high sunlight environments, I noticed that where my standard Oakley lenses would whitewash out most colors (I.e the blue in the sky around clouds, due to the sunlight), my Revant lenses showed a vivid blue and outlines of clouds. Now in the interest of honesty - I have not tried Oakley's new Prizm lenses, though it sounds very similar to these lenses. I was comparing the HC3 Elite lenses to standard Oakley lenses, and saw a noticeable difference. I will try to capture some pictures of this, but it is extremely difficult through a camera. Overall, I definitely see the application of these lenses. The contrast and color is undeniably better compared to standard Oakley lenses. To be honest, going in I had fairly low expectations, since I wasn't buying most of the marketing language selling me on "High Definition Lenses", but I will eat my words and say I am very surprised. Right now, the HC3 is only available in select frames, but I do look forward to them expanding further, and hopefully adding a "MirrorShield" Iridium coating, since this is a must have for a lot of people. Now let's open it up to Questions, comments etc!
