According to statistics, more than half of the users in Malaysia use tissue paper or cloth to clean their lenses when they are dirty. Some will use lens cloth to wipe which is not right as well. Lenses have grains of sand or dust, dry wiping the lens will damage the lens and in the long run significant scratches will be visible with our naked eyes. So, clean lenses with water.
For high lens usage users, it is recommended to clean minimum once a day, giving it a new look. Cleaning lenses not only can extend the life of the lens and frame, it can also give you clear vision.
