Not too rounded and with a large focal length, Johnny is made with extremely soft-touch material. It will pamper you with warm and enveloping colors.
Gradient lenses are those whose color 'opens' downwards. The choice of these lenses has to do with both aesthetics and comfort as they are more comfortable when looking at the near zone (car instruments while driving, mobile phone screen, etc.).
CLEANING: use a damp cloth and a normal neutral detergent and dry with a soft clean cloth. Avoid the use of solvents.
