Cleaning of the lenses Summer is a sweaty and rainy season. The lenses are relatively more likely to be contaminated with dust. Frequent wiping of the lenses also makes the lenses more expensive. In daily life, you should pay attention to the cleaning of sunglasses. If necessary, you can rinse them with professional cleaners or clean water.
