Advantages of polarisation

Seiko’s PolarThin technology introduces a whole new generation of high-quality polarised lenses coupled with unrivalled aesthetic properties. PolarThin are thin and stylish but still provide protection by filtering out glare caused by reflective surfaces.

How are polarised lenses made?

Previous generations of polarised lenses are often manufactured with the polarised film bonded onto the front surface of the cured lens, then a final resin layer is laminated onto the film itself (figure 1).
PolarThin lenses are manufactured by embedding the polarised film within the lens as part of the curing process, putting it simply, an initial layer of resin is placed in the mould, the polarised film is then applied, a final layer of resin coats the film. This is cured so that all materials become bonded and the polarised film is embedded within the material itself (figure 2).
