To clean the optical lenses of your glasses, screens, etc. look no further, VU is really the ultimate in quality. The product does what you ask him, he cleans all without leaving traces. Simply spray a low, guaranteeing a long service life of the bottle. This is my third purchased, each I kept it for months while I use it almost daily. So it is that the eco wipes. One last point: unlike other competing products, the smell does not bother me, it's a good plus point.
