Sunglasses

Why do you need special sunglasses for BMX or sports?

For sports, high-quality sunglasses are crucial for protection and performance. They not only protect your eyes from harmful UV radiation but also from wind, dust, insects, and kicked-up pebbles. At the same time, a good tint improves contrast and reduces glare, leading to clearer vision and less eye fatigue.

What do VLT and Filter Category (e.g., "Cat. 3") mean for sunglasses?

These two values are the most important indicators of how dark a lens is and for what conditions it is suitable.

VLT (Visible Light Transmission)

The VLT value indicates in percent how much visible light passes through the lens. A low value means a darker tint. For example, with a VLT of 18%, only 18% of the light reaches the eye, while the remaining 82% is blocked—ideal for sunny days.

Filter Category (Cat.)

The filter category, according to the EU standard, classifies the tint in levels from 0 to 4. Category 3 is the all-rounder for sunny weather and offers high protection against glare.

Category	VLT Range	Recommended Use
Cat. 0	80-100%	Very cloudy, dusk, indoor sports (protection without tint)
Cat. 1	43-80%	Slightly cloudy days, changing conditions
Cat. 2	18-43%	Medium sunlight, all-round use
Cat. 3	8-18%	Strong sunlight (e.g., at the beach, in the mountains)
Cat. 4	3-8%	Extreme light (glaciers, high mountains). Not suitable for driving!

What should I look for in the fit of sunglasses?

For sports, a secure and comfortable fit is essential so that the glasses do not slip during fast movements. Pay attention to the following dimensions if provided by the manufacturer:

Frame Width

The total width of the glasses from hinge to hinge. It should roughly correspond to the width of your face.

Frame Height

The vertical height of the lenses including the frame. Taller lenses offer a larger field of vision and more protection.

Nose Opening

The width of the nose bridge. A well-fitting bridge prevents the glasses from sliding down your nose.

How do I properly care for my sunglasses?

To avoid scratches and maximize the lifespan of your glasses, you should care for them regularly. For cleaning, it's best to use the included microfiber pouch or cloth and lukewarm water. Avoid aggressive cleaning agents and always store the glasses in their case or pouch when you are not wearing them.
