Lenses: Summer sun on the horizon

Hoya says its Polarised lenses effectively block reflections and eliminate annoying glare from the sun while increasing contrast and providing better comfort outdoors, even on extremely bright days. The product is available in a large variety of design, coating and material options and gives the opportunity to upgrade patients from conventional tinted lenses. The lenses have a polarised efficiency of over 98%, come in three colour choices and are said to offer contrast-rich vision.

Younger Optics says its NuPolar product sets the global standard for prescription polarised lenses. The company notes that, although there are currently no international standards that govern the quality of polarised lenses, NuPolar offers strong performance in eight crucial categories: polarising efficiency, heat stability, film adhesion, colour uniformity, axis alignment, thin film placement and transmittance.
