According to statistics, more than 50% of Malaysians use tissue paper or clothes to clean their lens when they are dirty. Some will use their lens cloth to wipe their dirty lens, which is not right as well. Dirty lens will accumulate some grains of sands and dust, and dry wiping the lens will damage the lens and in the long run significant scratches will be visible to the naked eye. Use water to wash away all small particles first before wiping them dry with your lens cloth.
For high lens usage users, it is recommended to clean at least once a day. Cleaning your lens can not only extend the life of the lens and frame, but also maintain the clarity of your view and any one time.
