Protection
It is important to differentiate between visible and invisible light (partially UV)
All our glasses protect from 100% of UV rays.
Even with a transparent lens, you will be protected; however, you may get glare. This is where the categories (0 to 4) come in.
Category 0 lets nearly all light through, while category 4, on the other hand, is very dark (ideal for high altitudes)
LENS
These glasses have a category 3 lens, meaning that it will absorb between 82% and 92% of visible light.
Category 3 is perfect for riding in sunny weather.
Not suitable for riding in overcast weather in winter. 100% UV protection, compliant with standard ISO 12312-1.
The mirror effect is aesthetic only. Beware of scratches, which are more clearly visible on a mirror lens. Keep them protected in their case.
HOW TO CARE FOR YOUR GLASSES
To keep your lenses in good condition and thus benefit from good vision quality, it is important to follow the following rules:
- always store your glasses in a protective case, particularly during transport
- never wipe your glasses when dry; always wash in soapy water first
- never wipe your glasses on your T-shirt or cycling jersey
- wipe/wash your lenses with a microfibre cloth only
CHOICE OF NOSE
These glasses come with several nose pieces.
There are two goals, the most obvious one being to adapt the frames to your face.
The second goal is less widely-known, but just as interesting: adjusting the nosepiece also adjusts the ventilation. The tighter the nose, the "higher" the glasses sit on the face and thus the further apart. This will give you better ventilation, which can be useful in summer.
REMOVABLE FRAME
The PERF 500 have a removable frame on the bottom part.Beyond the style component, which is a personal choice, this again allows you to adjust the ventilation based on your activity. When the lower part is removed, there is greater airflow inside the frame.
To remove the lower part, gently pull it sideways (not downwards).
