Abstract: A defog lens for vehicles includes a lens barrel, a lens, and a hydrophilic layer. The lens barrel has an opening toward an object side. The lens is disposed in the lens barrel and is located at the opening. The hydrophilic layer covers a surface of the lens and includes silicone compounds. Water droplets condensed on the lens could form a sheet film sticking to the surface of the lens and hard to form spherical water droplets, thereby improving the problem that the field of view of the conventional lens is blocked by spherical water droplets, effectively improving the clarity of the image captured by the defog lens, and therefore the defog lens could be applied to various environments.
