Cycling sunglasses are part of looking good and staying healthy on the bike.
Yes, other bike shoes, kit, socks, and helmet are a part of your biking experience. However, it is equally important to protect your eyes during your training rides and even your races.
When you decide to shop around for glasses, there are several factors you should keep in mind.
Of course, you can use your casual sunglasses, but if you’re a frequent rider, I’d recommend at least buying cycling-specific glasses.

1. Oakley Flight Jacket Prizm Road — Best Sunglasses for Cycling

The Oakley Flight Jacket cycling sunglasses were aerodynamically engineered that makes this pair of sunglasses ideal for cycling, running, and any other outdoor activity.

The sunglasses come in standard, Prizm, Prizm Polarized, and Photochromic lens options.
As mentioned before, standard lenses keep out 100% of UV rays and dim the sunlight if you’re biking in the middle of the day. Just be sure you can still see road bumps and pot holes with these lenses.
Oakley’s Prizm is best used for bright light conditions since it can transmit 12% of light. Instead of staring at bright colored buildings or light bouncing off the road, the lenses make the color look warmer and richer. You’ll be able to appreciate your surroundings because you won’t be squinting. The base color for this lens is purple.
The Prizm Polarized lenses essentially work the same as the Prizm lens. It’s best for bright light condition and makes all your surrounding look inviting and cozy. The base color for these lenses is orange. And the other difference is the light transmission. This one transmits 17% of light.
The last lens these glasses offer is photochromatic. This means that the lenses automatically adjust to whatever light condition you’re riding in. The contrast between using and not using these glasses is neutral. And, the base color for these lenses is clear.
The frame material, O-Matter (patented), is lightweight and durable so you can use them for cycling seasons to come.
This pair is ideal if you think you have a medium or large-sized face.
Cyclists who have bought the pair of sunglasses like it because it protects their eyes from the wind, sun, and any road debris. And on top of that, they never fog up and breath very well because of the lack of framing around the top. Cyclists say that the glasses are a bit large and can make them look like a bug, but for functionality, it works.
2. Oakley Jawbreaker — Best Road Cycling Sunglasses

The Oakley Jawbreaker cycling sunglasses look aggressive and mean with its taller and wider lenses to provide extended upper peripheral vision. This would be ideal for not just cycling and running but also any other recreational outdoor activities.
Like the previously reviewed glasses, this one comes with Oakley’s Plutonite lens that blocks 100% of all UVA, UVB, UVC and harmful blue light. And the glasses have Oakley’s Switchlock technology that enables you to swap lenses quickly.
To ensure that you have the best fit, the glasses have unobtanium nose bombs and ear socks to keep your glasses from slipping. And, this grip increases as you sweat. The glasses also have adjustable temple lengths so it can fit nearly any head and can be worn with any helmet.
Unfortunately, this pair of sunglasses doesn’t offer as many lens options has the last one, but it doesn’t make it a horrible option. If you only ride in a few types of weather conditions, then these glasses could work well for you.
The Prizm lens that comes with the glasses is great for medium light conditions and the lenses increase the contrast. It does give the road a slight purple tint since the base lens color is purple. But for your surroundings, it actually brings out the nicer and warmer color of green grass. And the sky looks less sharp in its brightness.
The Photochromic is best used for any type of road condition and the contrast is neutral since it depends what you’re riding through. Different from the Oakley Flight Jacket, these have a black lens base color for its Photochromic option.
Cyclists who have bought the pair or happy with it and like it because they provide great coverage and actually adjust well to the majority of face sizes out there. They are bigger than other cycling sunglasses brands, but they do give you the best coverage. Cyclist like that Oakley sells the pair for interchangeable lenses for early morning or night riding. And, the ventilation is well designed and works well. Some feel like the sunglasses come in limited size options and those with smaller faces feel the glasses slide down.
3. POC DO Blade Cycling Glasses

The DO Blade was designed with a sports frame, injected with Grilamid to make the glasses lightweight and durable. The lenses can be changed according to whatever condition you’re riding in.
These glasses can be adjusted to fit any rider’s face shape and size. The glasses have adjustable nose pieces and rubber inserts for smaller faces and shapes. The nose piece and rubber inserts are made of hydrophilic rubber so that the grip increases as your sweat or ride through the rain. The ensures that the frame stays firmly in place throughout your entire ride.
The design team created the lenses specifically for cyclists in mind. The lens tints increase the contrasts on the road surface and help riders spot bumps, holes, and debris on the road. The anti-fog and ripel treatments on the lens helps prevent fog from forming on the lens and repels dirt and grime off the lenses. And, the treatment makes the water pearl off if you’re riding in the rain.
All lenses are great for all-around light conditions and can be interchanged if needed.
Cyclists who have bought these glasses like them because they are light, look nice and have a wide field of vision. The lenses are great for all road conditions and there are enough options so cyclists feel comfortable riding no matter what the weather or cloud coverage is. On the road, the glasses really do a great job of blocking dirt getting into cyclists’ eyes.
I’d recommend this pair of sunglasses to anyone who needs good coverage and not too many lenses.
4. 100% Speedcraft — Best Perfomance Cycling Glasses

The 100% Speedcraft was made with its signature lens that has a cylindrical shield that features 360-degree visibility on the bike. The glasses also have ultra-grip rubber nose and temple pieces that help give you all-day comfort. And the lower air scoops increase ventilation and reduce moisture on the lens.
When you order this pair of sunglasses you also get a hard case, microfiber cleaning bag, nose pad, and a clear replacement lens. Not every brand offers this and if you don’t already have a glasses case then this would just be a “gift” to yourself.
Although if you didn’t have a glasses case, you could go to a drug store and buy one yourself.
The glasses durable since the lenses are high-impact resistant and the lenses are made of light-weight polycarbonate. The lenses also have a 5-base cylindrical shield lens so you can see peripherally and protect the side of your face.

Going on about the lenses these have the HYDROLIO lens treatment which repels water, dirt, and oil while you’re riding. No matter where you find yourself, you’ll be sure that your vision won’t be blurred.
Curious of the specs of the lens?

This pair of sunglasses give you a deep and wide field of vision since the lenses are wide and tall. When cyclists use these glasses, they can see further than when they used a different brand.
To ensure each cyclist has a precise and comfortable fit, the glasses have an adjustable nose pad and temple tips. Cyclists have reported little to no complaints regarding the fit of these glasses.

7. Smith Attack Max — Best Road Bike Glasses

Smith Attack Max cycling glasses features a larger lens for maximum visibility, fast lens interchangeable technology, two ChromaPop lenses, and two-position nose piece. This would make these glasses a good option for cyclists maxing-out their miles during the summer.
The ChromaPop is a patented Smith lens technology. The ChromaPop lens filters two specific wavelengths of light that cause color distortion. As a result, you get a bright, crisp vision and can to see the road or trail in exceptional detail.
The Smith MAG technology lets you very quickly swap your lens between both of the included ChromaPop lenses. Don’t worry if you only have seconds to change, the technology makes it possible.
Cyclists who have bought the Smith Attack Max cycling sunglasses because they have ChromaPop lenses and are frameless. Cyclists who are in the aero position or riding in the drop bars can easily see ahead without craning their necks to see the upper part of their vision. They also like well-designed peripheral vision coverage. And, there isn’t a center “pole” between the left and right eyes to get in the way.
Some cyclists compare the field of vision to ski goggles. It’s wide and crystal clear where to go.
Cyclists love that it comes with a hard case that carries both lenses and a microfiber sleeve.
The only downside might be the price for some and lack of color options.
I recommend this pair of cycling sunglasses to those who are interested in the ChromaPop technology or want to try a frameless option. The field of vision really is wide and if you’re nervous about seeing things on the road, you won’t need to be since there are few design structures.
If you’ve had trouble seeing over the top of framed sunglasses before, then this pair would be a good option. You won’t have to crane your neck while down in the drop bars or aero bars.
8. Tifosi Aethon — Best Sunglasses for the Money

Tifosi Aethon provides full coverage protection with a sporty style for those who need high-performance eye ware. This pair of glasses comes with a removable brow bar for your unique look and feel.
All the standard lenses by this company have UV protection so you can comfortably ride on the sunniest of days in the summer. And, the lenses have a glare guard so that it reduces the strain on your eyes. The glare guard is an extra coating on the lens.
The lenses were made with your vision in mind and what you need to see on the road. That’s why the lenses were optically decentered. This eliminates distortion and prevents unwanted magnification while riding.
The lenses are also vented so that it increases airflow. This helps prevent fogging and keeps your face cool.
Finally, the lenses are made with polycarbonate material, which is scratch-resistant and nearly shatterproof. Still, be careful with your glasses, but you won’t have to sweat over a fall off the café table.
This pair of sunglasses come in AC Red, Clarion Blue, or Clear colored lenses. The AC Red is great for all conditions your ride in and have 41.4% light transmission. The Clarion Blue is a mirrored lens so it really blocks out the sun and only transmits 14.7% of light. And, finally, the Clear lens is best used for late-night riding or riding in cloudy conditions.

10. Bolle Bolt

The Bolle Bolt glasses were designed for cyclists who do light to medium riding. It does meet the demands of the sport with interchangeable lenses but is a less intense version of the B-Rock models.
Compared the B-Rock, this one only has an adjustable nose piece instead of both nose and temple. For the nose piece, the shape and the angle of the nose piece can be adjusted to accommodate any shaped nose bridge. The nose pads are hypoallergenic and durable so you can be sure that you can use these glasses for several years.

Best Road Cycling Glasses — Buyer’s Guide

Reasons to Buy Cycling Sunglasses
Before I get into the different types of sunglasses and how to pick one, let’s talk about why.
Some of you may be skeptical about buying cycling-specific sunglasses, which is ok.
Here are a few reasons why you might consider looking at them before completing dismissing the idea.
1. Protect Your Eyes from the Sun’s Rays
Just like casual sunglasses, cycling sunglasses protect your eyes from the elements when you’re outside.
It’s not just the dangerous UV rays, but also winds that blow-up debris and dust particles, mud, raindrops and even the occasional insects that fly into your face.
As cyclists, you spend a lot of time in the sun especially during the summer, which is why protecting your eyes is no different from your skin with sunscreen.
If you regularly wear contact lenses, sunglasses are even more important as a cyclist. The sunglasses prevent your tears from evaporating so that your eyes are moist and comfortable.
2. For the Sake of Looking Fashionable

In recent years, cycling sunglasses have stepped their game up and transformed from being protective wear to fashion wear.
Cyclists, especially ones who consider themselves “hip” seems to have the latest trendy cycling sunglasses and accessories.
Of course, you don’t need the latest and most expensive sunglasses.
However, you can be sure that there are “attractive” options out there.
3. Look “Tough” on the Road and During Races

Professional cyclists started wearing sunglasses around the mid-90s and it really started to take off after Lance Armstrong wore them during the Tour de France in 1999 (his winning year).
In addition to protecting your eyes, some professional triathletes wear sunglasses to hide how tired they are from their opponents. If your competition can’t see how weary your eyes are, they won’t know how tired you are.
Types of Cycling Lenses
The most important part of any cycling sunglasses is the lenses.
The tint of the lenses will tell what type of conditions you can wear them in.
The more expensive glasses are treated with lenses that can be used in a rand of light conditions.
Don’t worry, you don’t have to spend a lot of money to get a pair of cycling glasses. There are cycling sunglasses that have interchangeable lenses that can be swapped out accordingly.
Most cycling sunglasses that have interchangeable lenses will come with three different options.
First, you should have a standard shaded lens that will provide 100% UV protection and dims bright sunlight during the summer. But, they shouldn’t be so dark that you can’t see road surface if you’re descending through a heavily wooded or pop-hole area.
The second lens should have a yellow tinge, which is great if you need to brighten things up if you’re riding in overcast conditions. This makes it easy to spot rough spots on the road in the dim light.
And, the third lens should be clear that you can use if you are riding after dark.
Photochromatic Lens
The other option for cycling sunglasses is buying one with a photochromatic lens. This is arguably the most versatile lens for you.
These lenses will change their lightness and darkness depending on the conditions.
When these first were advertised, they might not have been great since they didn’t change fast enough if riding in and out of shad.
However, the latest sunglasses are much better and offer quick changes in tint.
These would be a good option if you want to ride in different conditions but don’t want to change your lenses every other day.
Polarized Lens
The polarized lens should help block out reflected light from the road surface, car hoods or road signboard.
This type of lens should make it more comfortable for your eyes during your summer rides.
Remember, glare is caused by horizontal reflected light waves. And, polarized lens filters these out and only allows the vertical light waves to pass through.
Orange/Brown Lens
Besides clear lenses, orange/brown lenses are another option for those who ride in low lighting conditions. The orange/brown tint helps brighten up the road ahead of you.
Cycling Glasses for the Rain
Keep an eye peeled for cycling sunglasses that have a hydrophobic coating.
If you have a cycling hat, cycling sunglasses with hydrophobic lenses are very useful. The coating ensures that water doesn’t stay on the lens and impede your vision.
Cycling Sunglasses Frame

When you finally decide to purchase your cycling sunglasses, most of your money will be going towards the frame rather than the lenses.
This means you want to make sure that the frame fits well.
Here are a few tips to ensure the frame fits:
- The tips of the arms should fit snugly around your temples.
- When you look down or swing your head from side to side the glasses should stay in place.
- Use little rubber grippers to hold the glasses in place without needing to tighten the arms.
- Look for an adjustable nose piece so that the glasses don’t slip down your face while riding.
There are a few cycling sunglasses brands that have adjustable arms to ensure a good fit.
Generally, there are three different styles of frame design: full frame, half frame, and frameless. All these options offer similar function so you have a variety to choose from that suits you and your cycling needs.
Air Vents
When you ride, heat and perspiration tend to get trapped between the lens and your face.
But, if you have airflow, the heat and perspiration get displaced and hence no fogging. But once you stop at a traffic light, you’ll notice that the lens will quickly fog up.
Look for cycling sunglasses that have air vents on the lens that allow for additional ventilation and breathability that prevents the lens from fogging up.
Prescription Sunglasses
If you wear prescription glasses, you might want to look into getting prescription lenses for your cycling sunglasses too.
Some brands can supply prescription versions of most lens styles. Other brands provide clip-on inserts which can sit behind your sunglasses lenses.
Either option works and it depends on your personal preference. And both options can be ordered through your opticians and just adds an extra expense to your bill.
This is a practical alternative to wearing contact lenses underneath your normal cycling sunglasses.
Choosing a Pair of Cycling Sunglasses
What brand and style you ultimately choose come down to your personal choice.
But here are a few features any good pair of cycling sunglasses should have:
- Frames should fit snugly.
- Air vents to provide airflow and prevent fogging.
- Lens covers your eyes completely.
- Silicon or rubber grippers on the nose piece and temples which grips more during wet conditions.
- Adjustable nose piece.
Good luck on your search for sunglasses! We hope this article helps narrow your options. Sunglasses will keep you safe on the bike.
