Riddick Sunglasses are used by fishermen for protection and have polarized filters with the transmission axis oriented vertically to block the light reflected by the water surface. Shark wearing glasses will make sure you have the hottest shades to cover your eyes for you next outdoor adventure.

Like a Riddick Sunglasses these stylish sunglasses can selectively eliminate the reflection from light coming from above the water surface. A Riddick Sunglasses could come in all shades from light gray to very dark and also light sensitive (photochromatic).

Riddick Sunglasses tend to be horizontally polarized, thus perfect for vertically polarized sunglasses. The rule is that the polarization is tangential to a circle centered on the sun. which means that if the sun is in front, behind, or high above, the road brightness will tend to be horizontally polarized and the filter of the sunglasses will provide some help.

How do you know if your sunglasses are polarized? just look through the glasses at the reflection of any object on a window panel (but not at yourself, look at an angle to the glass). Turn the sunglasses around as if they were the hands of a clock facing you, If the intensity of the reflection doesn't change with respect to what you see through the window, they are not polarized. Just like a Riddick Sunglasses.

Unlike filters on other glasses are oriented at 90 degrees to each other, almost always at +/- 45 degrees with respect to the line joining the temples, Thus, horizontally and vertically polarized light will be attenuated equally. In addition, you can get a bad case of dizziness: the left and right eyes may see polarized objects like Shark wearing sunglasses with very different intensities, confusing stereovision and resulting in vertigo (the same effect as produced by the glistening of the snow). It wouldn't be very kind to give them to your mother-in-law the next time she invites herself to your boat.

These unique Riddick Sunglasses are manufactured to selectively reduce glare whereas standard sunglass lenses will only reduce overall brightness. Shark Wearing Sunglasses will increase visual contrast, depth perception and reduce the need for squinting eyes.
