Riding mountain bikes on bumpy trails means you need eyewear up for the challenge. Quality glasses specifically made for mountain biking protect your eyes while improving what you see on the path ahead.
Read on in this article which will guide you to what features to look for so you can find the perfect pair of glasses for safe and fun rides.
See the Trail Clearly
Your mountain bike glasses must above all give you excellent vision on the trail. Lenses should be very clear, help you identify hazards, and not distort the scenery.
See Small Obstacles
Quality cycling lenses allow you to spot even tiny sticks, rocks, and dips far down the trail. Lesser lenses can blur your sight and hide dangers that could cause a crash. Top lenses are made from strong polycarbonate or Trivex plastic rather than cheap materials. They resist scratches and deliver crystal clear optics with no warping. This allows recognizing obstacles early so you can pick the best line down technical sections.
Many quality MTB lenses also have an anti-reflective coating. This reduces glare from sunlight so you maintain excellent clarity. Significant glare can be blinding and make seeing the terrain ahead difficult. So quality glasses cut glare for a perfectly clear view.
See in All Light
Some sunglasses are too dark to ride with in dense woods. Their lenses don’t allow enough light transmission to spot roots and holes on shadowy trails. Other shades are too light for exposed ridge lines. Bright sunlight overloads your vision rendering obstacles invisible.
The best mountain biking lenses adapt to lighting conditions by auto-adjusting their tint. Photochromic lenses start lighter then darken when hit by sunlight. This single pair of glasses works great from dark forests to open meadows. Other lenses are swappable. Carrying an extra light and dark pair allows switching to suit different light levels. Either way, your vision stays optimized across changing trail conditions.
Built Sturdy for the Trail
Hard crashes and loose branches can crack weak frames. But lenses made for mountain biking stand up to years of aggressive rides.
Withstand Hits
Mountain bike crashes happen. Poor quality plastic lenses can easily crack or shatter when you go down, exposing your eyes to harm.
Quality cycling glasses have sturdy frames and shatterproof lenses built to withstand hits. The best are made of Grilamid or Optyl thermoplastic that flexes substantially without breaking. Others feature polycarbonate lenses which resist fracturing on all but the biggest impacts. These durable materials mean your glasses stay intact after crashes so they keep protecting your vision ride after ride.
Grip Tight
Even the most rugged glasses do no good if they shift around on technical sections. Proper stabilization with rubber pads ensures your eyewear won’t move even hitting big jumps or fast rock gardens.
Look for pliable nose pieces and temple tips made of sticky rubber or silicone. These grip your nose bridge and upper cheeks firmly in place over variable terrain. Quality construction keeps the glasses solidly positioned instead of bouncing around exposing your eyes to harm. Integrated head straps also reinforce stability on downhill runs.
Block Harmful Rays
The sun’s rays are much stronger when reflected off surfaces like water or snow. And trees don’t block all UV light. So quality sun protection is vital on mountain bike rides.
Block UV Rays
Without proper eye protection, UV exposure contributes to conditions like cataracts or macular degeneration over time. It can also cause short-term sunburn on the cornea.
All quality cycling glasses clearly state they offer 100% UV protection from harmful UVA and UVB rays up to 400 nanometers. This completely stops eye damage from the sun’s strongest rays even on all-day rides. Any tint level still provides complete UV blockage, so clear lenses work great for dusk/night riding.
Adapt Tint
Some lenses adapt their darkness when more sunlight hits them. As ride conditions change, photochromic lenses automatically transition from light to dark tints. This handy feature means one single pair of glasses works great from dark forests to exposed meadows with no swapping.
For those not wanting autoin-tinting, many glasses offer interchangeable lenses instead. This allows manually switching from a lighter lens for wooded climbs to a darker tint for open downhill runs. Either auto or swappable models allow a single frame to excel across changing light conditions.
Stay Put, Stay Comfy
If your mountain biking glasses are uncomfortable or ill-fitting, you won’t wear them enough to get their protection. Prioritize a custom fit for all-day comfort.
Grip Your Face
Even if glasses have shatterproof lenses, they do no good if bouncing around on your helmet. Proper stabilization with rubber pads ensures eyewear stays firmly over your eyes the entire ride.
Look for pliable nose pieces and temple tips made of sticky rubber or silicone. These grip your nose bridge and upper cheeks solidly despite heavy trail vibration. Integrated head straps also reinforce stability on aggressive downhill runs. Quality sticky pads customized to your face prevent slippage so protection stays optimal.
Flow Air
Lenses fogging up with sweat or moisture severely reduces trail vision. On hot uphill pedals, inferior glasses trap heat and condensation making seeing ahead impossible.
Quality cycling frames maximize airflow circulation behind the lenses. Open-cell foam pads allow passing air rather than sealing it out completely. Vents carved into lens bodies channel humidity up and away. Keeping internal air flowing freely ensures no bothersome fog accumulates even on the toughest climbs.
Fit Your Helmet
Mixing incorrectly sized cycling glasses and helmets leaves dangerous gaps in protection. Eyewear arms should tuck seamlessly under helmet straps with no overhang. Lens width should not exceed the helmet face opening or debris can sneak under.
When shopping, make sure to bring your preferred helmet. Try on multiple sizes and models of glasses to understand the interface. Temple arm angle, lens surface area, orbital shape all impact helmet pairing. Getting lenses flush within your lid ensures nothing penetrates from the sides. Dialed fitment prevents unwanted debris blowing into suddenly exposed eyes.
Stay Lightweight
After long days of riding over bumpy terrain, heavy glasses with bulky frames become uncomfortable. The increased mass compounds vibration and strains delicate facial nerves.
Seek out lightweight but durable materials like Grilamid polymer for the frame. Quality thermoplastics like Grilamid resist cracking better than cheap plastics while still keeping mass down. This balances impact resistance against wearing comfort over long periods. If available, weigh different models to compare relative heft.
Prioritize lenses fitting flush within stabilized rubber pads. Outsized lenses may protect better but greatly increase weight and instability. Find the ideal balance of coverage versus mass that suits your riding needs.
Find Your Perfect Fit
While seeing all the technical features above helps narrow the choices, you still need to try shades on in person. Everyone’s face shape and ride style differ slightly. Make sure to test sizes and models at the store. Check that frames pair seamlessly with your helmet and deliver the visual coverage you want. Tiny details like grip patterns supporting all-day comfort matter too.
Don’t neglect small touches like venting channels or adjustable nose pads that customize fit. Take time to test spectacle arms tucked neatly under your helmet straps. Try glasses right over your typical eyewear if needed. Investing time upfront to test shades helps find that perfect pair to bring clarity and protection to all your future mountain bike adventures.
