Shield Sunglasses are sunglasses that are composed of one continuous lens spanning the distance normally covered by two separate sunglass lenses and a nose bridge. Shield sunglasses often have the shield cut and finished from exactly one piece of lens material, whereas traditional sunglasses may utilize multiple lens elements. In rare cases, two lenses are fused together side-to-side to create a shield lens, but this manufacturing method leaves an unsightly seam with some distortion as well.
Shield-style sunglasses are popular sport sunglasses prized for their unparalleled field of vision, lightness, and easy on-and-off design. Most shield frames either only have frame material at the temple, or occasionally on top of the frame. There is usually negligible frame material along the bottom of the frame as that typically inhibits a maximum field of vision. This is how shield lenses achieve the best FOV.
Because the shield sunglass lenses stretch continuously across a wearer’s face, it is possible to have an enhanced field of vision in front of the sunglass frame’s nose bridge.
Normally the field of vision in front of the nose bridge is cut off, and prevents quality perception of depth, because with closer distances the brain is only processing an image from one eye. Shield sunglasses allow vision directly in front of the wearer’s nose bridge, enabling a stereoscopic view of the road ahead, enhancing depth perception.
Shield sunglasses also enhance peripheral vision because the lack of rims along the edges of the lens means an obstructed view of the environment and any important subjects, such as a ball, other players, even pedestrians, bikes, and cars.
Polarized shield sunglasses apply a layer of polarization to shield lenses that removes horizontal waves of light which cuts glare and making objects in the field of vision easier to see. Shields have the added bonus of offering the most unobstructed vision, and when coupled with polarization technology, offers the most unobstructed glare cutting than other sunglasses.
Typically, the lens material and frame material used in polarized shield style sunglasses are from different materials. Polycarbonate,Trivex and occasionally nylon for lenses, and plastic, nylon, or grilamid for frame or temple materials.
Occasionally prescription shield sunglasses can be created by fusing a shield lens with a prescription portion. Oakley makes the best solution, and Bolle offers the only other available prescription sunglass shield solution. Both can be head in either polarized or non-polar variants.
