Review on Men's SmartVLT Silver Titanium Sunglass Replacement: Accessories for Sunglasses & Eyewear by Yung Kitamura

I find these lenses a good deal for the price ($23). They're definitely thinner than Oakley lenses, which means they still appear to be of decent quality. . However, the reduced thickness makes my goggles feel less stiff than with the original lenses (lens and frame work together to provide overall stiffness). The fit is good and the lenses stay firmly in place with no extra movement. I bought the photochromic ones as I mainly use them for mountain biking and cycling and getting in and out of the woods. It's difficult to find a lens that works in all conditions. Haven't noticed them getting too dark yet, but they should cut off the highlights pretty well. One weird thing about them is that they have a weird rainbow effect when I look at my phone, which of course doesn't bother me, but it's weird.
