I wanted a set of cycling glasses which I would use first thing the daybreak and additionally which would darken as the sun rises. I thought about the Oakley jawbone as well as the Rudy Project Rydon that includes photochromic lenses. Adjustability For me personally could not get the Oakley jawbone to suit absolutely comfortably. The sunglasses arrived provided with two nose accessories yet I could not get a excellent fit.. Even so the almost unlimited adjustability of the Rudy Project Rydon shades, the temples along with the nose bridge are exceedingly variable, resulted in I could get to fit properly without difficulty. Exchangeable lenses I personally wear the sunglasses for both mountain cycling together with road cycling and in addition needed a set of glasses that I could actually replace the lenses on. Both of those pairs of sunglasses take a completely different procedure but the Rydon was indeed certainly the most convenient to interchange ones lenses. With the Oakley Jawbone this seemed like I was doing major procedure with the glasses and I also could possibly be troubled about replacing your lenses in the open. The specific Switchlock technology is extremely easy however it seemed like the actual body comes to pieces to merely change the particular lenses. Unquestionably the Rudy Project system of simply pressing the particular lenses in and out is way less difficult as well as the lenses continue to stay firm. I favor make use of the clear photochromic lenses whilst out road cycling and use the red-colored photochromic lenses while out off-road cycling. This particular red lenses provide you with greater contrast as opposed to transparent lenses and are generally greater for picking out roots along with other difficulties over the tracks. Typically the Rudy Project Rydons continue to be fog free whilst biking although I’m exhaling heavily on hill ascents and only have a tendency to fog up if I stop and exhale really hard. Nevertheless they immediately clear if I begin moving once more or else remove them quickly from my face. Prescription Lenses Yet another major added bonus for my situation was the availability of an click-on click-off insert for my prescription lenses. I commonly wear lenses while cycling for long intervals, but yet generally when I’m going out for a hour or two cycle then this ability to easily click-on the insert is a major benefit and I also do not want to use a set of contacts just for a brief cycle. In comparison to some less expensive eyeglasses, the Rudy Project Rydon did appear quite expensive at first, but considerably cheaper versus the Oakleys. However with a bit of looking around on the net I purchased all of them through www.sportandspeed.co.uk. Exceptional service and even delivered next day. As a whole, I am extremely delighted with the sunglasses and the guarantee with the lenses will make sure that the Rudy Project sunglasses will remain my best cycling glasses for a long while.
