PHOTOCHROMATIC TECHNOLOGY of Kalenji Running Glasses
The lenses are activated by UV rays and deactivated when the UV rays diminish. The lenses need time to adapt to this technology (activation/deactivation) and this adaptation period varies according the outside temperature.
Activation = 30 seconds (whatever the temperature).
Deactivation takes between 1 min (above 20°C) and several minutes (below 10°C).
In cold weather, the deactivation time takes longer.
Car windscreens block UV light.
How to clean your Kalenji running glasses
Running glasses, like eyeglasses, should be carefully cleaned with suitable products to avoid scratching the lenses and blurry vision caused by dirt.
Do not use household maintenance products, disinfectants or acetone for cleaning. These products can damage the lenses as well as the coatings.
The only products you need to apply are some lens cleaning spray, liquid soap or washing-up liquid and rinse thoroughly afterwards.
How to adjust the ADJUSTABLE NOSE BRIDGE on your Kalenji running glasses
The RUNPERF PHOTOC Running Glasses are adjustable at the nose to increase their stability, comfort and ventilation capacity.
The more space there is between the lens and the cheek, the more ventilated the lens will be.
How to choose the lens tint (category) of Kalenji running glasses?
There are several categories of running glasses.
The RUNPERF PHOTOC are category 1-3 (photochromatic).
Photochromism: capacity to change tint according to brightness.
The lens automatically adjusts to light intensity; the tint transition is smooth and not noticeable to the eye.
The more the light intensity increases, the more the lens shades (activates) and the more it diminishes, the more the lens clears (deactivates).
