Sunglass Rob goes over some key things to know when buying your next MTB sunglasses—the dos, the donts, and the definitely nots.
Comfort and lightweight frames should be top of mind for mountain bike sunglasses. Most sporty or MTB-specific frames are made of a lightweight and comfortable nylon called TR-90. Different brands have different names for this material; Oakley’s O-Matter is one example.
Rob emphasizes to avoid acetate or metal frames for mountain biking. Acetate frames like on the Ray-Ban Wayfarer are great for casual wear, but they’re slightly heavier and not as flexible so they’re not ideal for mountain biking. Metal frames, on the other hand, are lightweight but break easily in a fall and can even pierce your skin if you’re in a bad crash.
You want your temples to fit comfortably and not be too long or too short. Look for straight temples or with a slight hook to them, as these are best for helmet compatibility. You also want rubberized grip on the temples and nose pads. Make sure your sunglasses of choice have grip in at least one of those places, but preferably both.
Wind, dust, and other random debris can get kicked up as you’re on the go so having a wraparound or 8-base frame will protect your eyes more than a flatter frame. Rob notes that a lifestyle look has been more popular for MTB lately, so if you’re after that more everyday style, opt for a 6-base frame so that you still have some coverage on the bike.
Rob’s #1 tip for MTB lenses? Less stop, more pop!
Contrast-enhancing lenses, like a rose or amber tint, are the most important thing to look for. They’ll give you the ability to go in and out of shadows without losing the details of your environment. It’s better to go lighter rather than darker for MTB, since your eyes will adjust to a lighter tint but a dark lens can muddy the trail.
Rob says it’s important to not go for a grey lens. This is something he sees a fair amount, but grey lenses don’t provide contrast enhancement and might cause you to miss a rock or bump in the trail.
Luckily for you, most brands have their unique contrast-enhancing lens. For Oakley, it’s PRIZM Trail, which is designed specifically for a mountain bike environment. These lenses are made to boost the contrast in the colors that your eye is most sensitive to while also filtering out the noisy, distracting colors. PRIZM Trail helps you to react quickly to your surroundings, making for a safer ride.
Similarly, SMITH proprietary lenses are called ChromaPop and heighten contrast, allowing you to pick up on all the necessary details on the trail. There’s also 100%’s HiPER lenses, another great contrast-enhancing technology.
Photochromic lenses, better known as transition lenses, are great for mountain biking because the lenses darken as more UV light comes in contact with the lens, and lighten as sunlight lessens. A common misconception with transition lenses is that they will change instantly. If you are riding in and out of shadows, they’ll start changing right away but will still take a bit of time to adjust. However, they are a great option to meet multiple riding conditions. Another plus to photochromic lenses is that you don’t have to bring multiple pairs of sunglasses or lenses to change out.
Another alternative to photochromic lenses, interchangeable lenses mean you can get one frame for multiple sports or lighting conditions and switch out lenses as needed.
We get asked a lot if polarized lenses are good for mountain biking. The answer is no. As Rob explains, a polarized filter that blocks glare usually results in a darker lens, and we explained why darker lenses aren’t a good option for mountain biking earlier.
The other reason is that studies have shown polarized lenses can throw off depth perception. Being able to judge your distance from oncoming terrain is crucial in mountain biking since your reaction time is related directly to what you perceive on the trail. Besides, there’s usually very little glare on your typical trail anyway, so there’s no need for a polarized lens.
Rob’s biggest caution tip is to avoid glass lenses. We love tempered glass for everyday sunglasses, but it’s too much of a liability in MTB. You can damage your eye or even lose it if you take a tumble.
Aside from not getting glass lenses, we already suggested avoiding acetate or metal frames, dark grey lenses, and polarized lenses for mountain biking.
