Sports sunglasses should not be chosen in the same way as everyday sunglasses. In high-speed sports, the lens and frame work together as a true protective system: relative wind can dry out the eyes and cause watering, while glare from asphalt, water and snow increases exposure to ultraviolet rays. In this guide, you’ll find the factors that really matter: protection, the right lens for the light conditions you ride in, a secure fit and integration with your helmet.
Briko sunglasses are designed in one size. Fit is not selected by size, but adjusted: the soft rubber nose pad adapts to the bridge of the nose, the temples conform to the shape of the head, and the TR90 frame remains flexible without losing its shape. This means the choice should focus on the lens and intended use rather than size.

A fixed lens has a single category and performs best when you usually ride in the same conditions. A photochromic lens automatically adapts to changing light and is the most convenient option on routes that alternate between sun and shade, such as wooded sections or climbs through valleys. Interchangeable lenses, on the other hand, allow you to carry two different configurations and choose the most suitable one before setting off, based on the weather.
In addition to the category, lens colour also matters, as each tint enhances contrast differently. Clear lenses and pink or yellow tints help in low-light conditions or on uneven terrain. Mirrored lenses and darker tints are designed for bright sunlight. Sharp Lite technology focuses specifically on this aspect, enhancing colour contrast and the perception of details.

On the road, a wide field of vision and a frame that remains stable at high speeds are essential.
For gravel and mountain biking, side protection from dust and debris and a lens that enhances contrast in wooded areas are particularly important.
For urban use, the focus is on balancing protection with a more understated design.
For Lifestyle, lightweight construction is key, as the sunglasses remain on the face for hours.
In high-speed sports, the frame must remain secure even when you sweat and move your head. Adjustable temples and the rubber nose pad are designed for this purpose, distributing pressure without creating uncomfortable contact points. A wraparound design adds side protection against wind, dust and insects, while TR90 absorbs impacts while remaining lightweight.
Adjustable temples allow the fit to be tailored to the shape of the head, providing a more secure, stable, and comfortable fit during every sporting activity.
The soft, flexible nose pad adapts to the shape of the nose bridge for a customized fit and enhanced grip, even when worn under a helmet.
The ultra-lightweight TR90 frame is flexible and impact-resistant, adapting naturally to facial movements while maintaining its shape over time.
Cylindrical polycarbonate lens technology. Category 2 (18–43% light transmission) or Category 3 (8–18% light transmission). Anti-fog treatment and 100% UV protection.
Sunglasses and helmets should be considered as a single system. The temples need to fit beneath the straps without creating pressure on the temples, the top of the frame should not interfere with the helmet shell, and the nose pad should maintain its grip while wearing the helmet. Briko sunglasses are designed to integrate with Briko helmets and most helmets available on the market.
Before setting off, check that:
✔ The sunglasses remain stable when you move your head
✔ The nose pad sits comfortably without leaving marks
✔ The temples do not put pressure on the sides of your head
✔ The lens should protect the eyes without restricting peripheral vision
✔ The overall fit should work with the helmet without creating pressure points
Clean the lenses only with a microfibre cloth, avoiding paper tissues and rough fabrics that could damage the surface treatments. Store the sunglasses away from impacts and scratches when not in use. Micro-scratches that interfere with vision, loose temples or a deformed frame are signs that it may be time to replace the sunglasses or the lens.
Most Briko sunglasses are designed in One Size. Comfort and fit are ensured by adaptive features such as an adjustable rubber nose pad, ergonomic temples, and TR90 frames—a lightweight, flexible material that adapts to the natural movements of your face during sports activities.
Yes. Briko offers lenses designed to deliver optimal performance in every lighting condition. The different filter categories, from Cat. 0 to Cat. 3, cover all needs: from low-light conditions to the brightest sunny days. For greater versatility, some models feature photochromic lenses that automatically adapt to changing light conditions, covering ranges such as Cat. 0–2, Cat. 1–3, or Cat. 0–3. Sharp Lite technology enhances contrast and detail perception, while all Briko lenses provide 100% UV protection and an anti-fog treatment for consistently clear vision.
In low-light conditions, Category 1 lenses are the ideal choice, allowing 43 to 80 percent of light through. If your ride involves very different conditions, for example starting in the dark and returning in bright sunlight, the most convenient solution is a photochromic lens that automatically adapts to changing light.
A photochromic lens is the most practical choice when light conditions change during your ride, as it adapts automatically. Interchangeable lenses are better suited to those who ride in very different conditions and prefer to choose their lens configuration before setting off, or those who want a dedicated lens for bright sunny days and another for low-light conditions.
Polarised lenses significantly reduce glare from wet asphalt and reflective surfaces, improving visual comfort in bright conditions. Keep in mind that polarisation can make some LCD screens, such as cycling computers, more difficult to read.
All Briko lenses feature an anti-fog treatment. The frame design also promotes airflow, which is essential for limiting condensation when you stop after intense effort or tackle a climb at low speed.
If you wear prescription glasses, there are two options: contact lenses or a prescription lens adapter, available for selected models. Check the product page to see whether the model you are interested in supports this option.
Yes. The rubber nose pad maintains its grip when a helmet is worn, while the temples are designed to fit beneath the straps without creating pressure. When wearing the sunglasses, make sure the temples are not compressed between your head and the helmet shell.
Use only a microfibre cloth and, if necessary, water. Avoid paper tissues, clothing and aggressive cleaning products, as these can scratch the lens and compromise the anti-fog treatment. Store the sunglasses safely away from impacts when not in use.
Some models are supplied with multiple lenses and state this in the product name, such as REVERB SHARP LITE 3 LENSES and STARLIGHT 2.0 3 LENSES. The magnetic lens-change system allows you to replace the lens in just a few seconds, even while wearing gloves.
