Which type of lenses are known to be very reflective and obscure the wearer's eyes?

Mirror coated lenses are designed with a reflective coating that significantly reduces glare from surfaces like water, snow, or roads, making them ideal for outdoor activities. The coating gives the lenses a shiny, reflective surface that not only obscures the wearer's eyes from view, but also enhances aesthetic appeal for some users.

One of the main features of mirror-coated lenses is their ability to reflect light rather than letting it pass through, which can create a striking look while simultaneously offering some level of privacy. This characteristic makes them particularly popular for sunglasses, as they help in reducing the amount of visible light that reaches the eyes.

In contrast, polarized lenses reduce glare without a mirrored effect, while gradient lenses offer different shades across the lens, and photochromic lenses adjust to light conditions but do not specifically obscure the eyes. Each of these types serves different purposes, which highlights the unique characteristics of mirror-coated lenses in visibility and reflection.
