Polarized

Sunlight causes glare, which leads to a loss of depth perception and other problems related to vision. For reducing glare from bright reflective surfaces like water, land and snow, polarized goggles are used. Polarized shades are different from tinted ones in the sense that tinted lenses are not able to completely protect one’s eyes from the harsh glare regardless of how dark they are.

Not all shades have UV protection, so it is best to check out the specifications first. While polarized glasses are not suitable for viewing LCD displays, they are great for outdoor sports. Cooling glasses are useful for reducing headache and eye strain when one is out in the sun. Just as sunglasses are colloquially known as sunnies in Australia, New Zealand and Britain, cooling glasses are used as a synonym for shades in Southern India. There are two major reasons: the first being, dark shades are able to protect the eyes from the sun; and secondly, the name works as a pun in a playful way that denotes a stylish demeanor.
