How to Choose the Best Glasses For Mountain Biking

The vast majority of people are looking for a pair of glasses that provide a good amount of protection, perform well under various conditions, and look great.

Yes, the first two qualities of the sunglasses might be the most important, but if a person is spending a lot of money on glasses, they also want to feel very confident when they wear them. With so many options shaped for specific faces, it just makes sense to invest properly.

Shopping online can be challenging for something that comes in so many different sizes, and that is why people need to be smart about the decisions they make.

This is a guide for people who look at the top options above and still do not know which way to turn.


Fit is a challenging thing to figure out when shopping online, which is why it is always recommended to go try some on in person at first. Even if the goal is not to purchase the sunglasses in person, it still gives a pretty good idea on expectations.

Take note of measurements and use all of the knowledge online to make smart decisions to avoid having to return a lot of different options.

The vast majority of mountain bike sunglasses are going to have straight temple arms that work well with any helmet. It is obviously very important to make sure that the sunglasses fit with a helmet on because no one wants to be in a tough situation where they have to invest in a new helmet to wear the sunglasses they just bought.

A lot of sunglasses also come with adjustable solutions, so a person never has to feel like locking themselves into a certain type of fit.

Sizing adjustments might take a little bit of time at first, but they are crucial so that glasses do not move around and they feel comfortable even during long rides.

Riding Style

Not all sunglasses are created equally when looking at the shape of the lens, as well as the tint. For a person to feel very comfortable wearing sunglasses in various forms, they need to make sure that they get what works for them best.

The ultimate type of protection will be glasses that have large lenses that curve in very close to the face. Having the eye almost completely enclosed will protect a person against any debris that might kick up.

If a person is worried about getting anything in their eyes at any time, this is a necessary option.

A lot of glasses these days are very easy to switch lenses in and out of, which is always an advantage for people who do not want to spend additional money on many different frames.

With that said, having the right tint for different riding times is crucial. It is particularly crucial for those who actually need corrective lenses so that they can see in the first place.

The most basic type of glasses for mountain bike riding will be standard tint for helping with the sun. Polarized lenses are the preferred option for a more enhanced view, but non-polarized lenses can work in many instances as well.

Clear lenses are perfect for those who want protection but do not really need to block the sun at all. Finally, some lenses actually enhance vision during dusk so that people can see a little clearer.

Being stuck in a dusk situation can sometimes be worrisome for people who are riding.


Mountain bike lenses are as light and comfortable as possible these days, and companies are always pushing the limits to reduce the feel overall. In many cases, those who get the right fit are going to feel like they are wearing nothing at all.

This is good news for people who want to have protection at all times, without feeling like they are weighing the face down at all.

To get this great feel, people need to make sure that they order the right glasses, and they make the proper adjustments so that they do not move around the face.

Right off of the rack, no pair of sunglasses is going to fit a person perfectly. It takes a little bit of time and effort, but it is worth it in the end.

Final Tips When Shopping For Mountain Bike Glasses

A helmet is an essential piece of equipment for anyone out there, but so is having proper eyewear for any situation. Some people can’t ride without wearing sunglasses, as they need to be able to see as clearly as possible.

Others just need some protection for the eyes so that they stay as locked in with their vision as possible.
