How it works?
How self-clean feature works
These frames are specially designed with built-in lens cleaning pads (see cut out diagrams below). As the lens pass through the frame in the cleaning steps, the cleaning pads can wipe clean the lens surface on both sides. These pads are made from high-end microfibre cusioned with soft sponge inside. Microfibre is the same material use for general lens cleaning to effectively remove dust particle, water drop and oil. The inner sponge act as cusion to protect lens surface. It can imitate the same strength and softness as using hands to wipe lens with cleaning cloth. In addition, the frame is made from super flexible and durable material known as TR90 to support this feature.
