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 adjust the ADJUSTABLE NOSE BRIDGE on your Kalenji running glasses
Our RUNSPORT PHOTOCHROMIC glasses have an adjustable nose bridge.
You can use this to adjust the latter, by manually moving the nose pads further apart or closer together, to adjust them to fit the shape of your face.
Proper adjustment increases the stability, comfort and ventilation because the more space there is between the lens and your cheeks, the more ventilation the lens will get.
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.
