Changing Weather Conditions?
The Arfa sunglass / goggle fitted with NXT photochromic polarised lenses is produced in our Australian factory. The NXT photochromic lens will darken in full sunlight to CAT3(Australian Standards) and lighted in overcast, foggy or darker conditions to CAT2. Choose between either grey or copper lenses.
Grey lenses are best for salt water or harsh sun conditions, as the grey colour neutralises the sunlight.
Copper is said to be best for fresh water or low light conditions, as the copper gives you high defined vision
