POLARISATION
GLARE PROTECTION
Polarised lenses are specially designed to reduce glare from surfaces such as roads, water and snow, as well as blocking harmful UV rays. Reflective glare distorts the true colour of objects and makes them harder to distinguish, often causing eye strain and making you squint. Our selection of sunglasses fitted with polarised lenses are useful for driving, fishing, boating and beach sports where glare can interfere with outdoor activities.
