What Is Hydrophobic Coating?
It's basically a 20-30-nanometer transparent coating of titanium dioxide that is placed on the surface of the lens. Hydrophobic coatings are not something new as people are making use of this for a long time on their prescription eyeglasses.

What is an Aspheric Lens?
Traditional lenses have a bulgy, curved shape. Imagine the spherical surface of a ball. An aspheric lens is designed with less curvature than its traditional counterpart. Think: flatter and thinner. In both farsighted and nearsighted prescriptions, aspheric lenses provide a slimmer profile and minimize eye distortion without compromising optical quality. Let’s take a look at how conventional lenses are designed for far and nearsighted prescriptions:
* Lenses for farsightedness have a convex curve, meaning they are thicker in the center and thinner at the edges. The stronger the prescription, the more the middle of the lens bulges outwards creating what is often referred to as the “coke bottle effect.”
UV Protection
What is UV 400?
Simply put, UV 400 means that the lenses will block Ultraviolet (UV) waves shorter than or equal to 400 nano-meters (nm). All UV waves come in different lengths as shown in the chart below.
UVA: 320-400 (nm)
UVB: 290-320 (nm)
UVC: 200-290 (nm)
Since all of these UV rays are shorter than or equal to 400 nm, they are blocked by the lenses - keeping your eyes safely protected.
This also explains why you can still see color. The color red has a wavelength of 680 nm. Since it is greater than 400 nm, it is not blocked by the UV 400 lenses.
