Peeper Window Fresnel Lens
AVOIDING TRUCK BLIND SPOT ACCIDENTS
Side-swipe accidents involving trucks of all types, are mostly caused by mirror blind spots and happen on highways around the world. Invariably side-swipes happen at the moment a vehicle is alongside a large truck, coach or van when a lane change manoeuvre is made by either of the two vehicles.
In the case of US trucks, there is a driver blind spot on the passenger side of the cab alongside the fender mirror, near the front turning wheels. To aid driver vision into this area many US trucks have a ‘peeper window’ located in the lower section of the passenger side door. Although this window is quite small, it does allow an extra view alongside that door which is very helpful in moving traffic conditions. As a further enhancement to the driver’s vision , this window is now often press fitted with a wide angle Fresnel lens so that it affords an increased field of view in order to limit that dangerous blind spot area further still.
FIT A FRESNEL ‘PEEPER’ LENS
Fresnel lens visibility windows are visual aids for safe driving that utilize the benefits provided by the wide angle optical properties of Fresnel lenses. 
Our lenses are available in a wide range of Focal Lengths and Focal Point positioning and they have been accredited for use at select major US trucking manufacturers.
We specialise in working with our partners and original equipment manufactures to produce soft pliable PVC and rigid (acrylic) PMMA plastic Fresnel lenses for Tractor units and other commercial vehicles. Additionally, we have the technical expertise to provide consultancy, design and manufacturing for in-vehicle ‘Peeper’ or passenger window glass applications such as water based, clear adhesive and glass sandwich Fresnel lenses.
Our lenses cover forward, rear or downward angles or a combination of views with positive or negative Focal Lengths, providing extended vision without the use of extra mirrors, expensive cameras or other detection systems
