What are water-coated wipers

The principle of water-coated wiper

Putting the windshield under a microscope, it is not completely flat. There are many gaps on the surface of the glass. When it rains, water molecules will seep into the gaps.

Ordinary wipers cannot remove the water molecules in the glass gap. Water molecules in the gaps still affect light refraction, causing blurred vision.

The function of the coated wiper is to form a uniform coating on the glass surface to fill the gaps on the glass surface and make it completely flat. Rainwater can't seep into the gap, it will bounce up and form water droplets to slide down.

The below is after using water-coated wipers

Scenario experience: no loss of vision under any circumstances

When driving above 60km/h, water droplets are quickly blown away by the wind

Conclusion: water-coated wipers is more safety
