TECHNICAL INFORMATIONS
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)
Photochromic lenses.
These glasses have category 1-3 photochromic lenses, which means they change category depending on the weather.
The lenses tint in about 30 seconds (45 seconds to deactivate).
The perceived brightness does not change much even when the outside brightness level changes.
For example, when cycling, the change in tint is almost imperceptible.
The tint changes smoothly and the eye adapts at the same time
A cold temperature will activate (tint) the lens more quickly.
HIGH DEFINITION LENS
These high-contrast road cycling lenses have been specially designed to enhance the most common colours you see on your bike rides. This gives blues, greens and greys more contrast so that you can make out more details.
Tests showed that cyclists greatly preferred these lenses over classic category 3 lenses (with a grey or brown base)
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 at the bottom. 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).
