Smith Optics Witness

Carbonic TLT Lens

The Smith Optics Witness have carbonic TLT (tapered lens technology) lenses. Engineered to be the most impact resistant lens material in the world, Carbonic TLT lenses are optically corrected to maximize visual clarity and object definition. Carbonic TLT polarised and non-polarised sunglass lenses are ideal for sport and casual use.

TLT - Tapered Lens Technology

The Smith Optics Witness come with TLT lenses. Tapered Lens Technology corrects distortion by progressively tapering the lens from the optical center towards the outer edges. Light waves that would normally bend or distort creating an illusion of an objects size or position are thereby delivered straight to your eye resulting in zero distortion and true optical clarity. What you see is what you get.

Polarised Lenses

Polarised sunglass lenses block out a lot of scattered and reflected light (glare). For example, if you look at water in a pool with a standard lens, it is difficult to see an object under water clearly. This is due to the fact that the surface of the water is reflecting light from all different directions. Smith Optics polarised lenses filter those reflected rays so you can see below the surface of the water much more clearly.

Smith Optics polarised Lenses are manufactured using a special material designed to block out glare and only transmit useful light to your eyes. This optically engineered polarising material is a very thin membrane sandwiched between two pieces of optically ground lens material to filter out 99 percent of all reflected light for maximum eye protection.

However, there are some limitations to the use of polarised lenses, some drivers discover that polarised lenses can cause distortions in liquid crystal displays (LCDs). Onboard clocks and other instrument displays may be temporarily unreadable.

Advantages: fantastic for all water sports, especially fishing, where the polarising filter allows vision through the surface reflective glare.

Grilamid TR90 Frames

The Smith Optics Witness sunglasses have grilamid TR90 frames that are light weight and extremely tough. TR90 frames have a high bending strength and strong resistance to chemicals and UV damage. Grilamid TR90 sunglasses frames will maintain their shape under all temperature conditions.

8 Base Lens Curvature

The Smith Optics Witness have an 8 base lens curvature. The base curve is the radius of the sphere measured from the back of the sunglass lens. Sunglasses typically come with either a 6, 7, 8 or 9 base lens curvature.

Sunglasses with an 8 base curvature will wrap around your face to protect you from the elements.

Category 3 Lenses

The Smith Optics Witness have category 3 lenses that meet the AS/NZS 1067:2003 standards for lenses. Category 3 sunglasses offer high sunglare reduction and good UV protection.  The majority of the sunglasses sold through out Australia are category 3 sunglasses.

Smith Optics Micro Bag

The Smith Optics Witness comes with a micro fibre bag. The Smith Optics micro fibre sunglasses bag is great for cleaning the lenses of your smith sunglasses or for protecting your sunnies from scratches.
