Why use Polarised lenses?

We've all experienced glare in our daily lives. You have probably noticed it on the sea at the beach, bouncing from the roadway or bonnet or on a boat reflecting from the surface of the water. Glare is uncomfortable and can be annoying, but reflected at just the wrong angle, glare can be dangerous, such as times when driving.

On polarised sunglasses, the filter creates vertical openings for light. This means that only light rays that approach your eyes horizontally can fit through those openings. As a result objects look crisper and clearer, and details are easier to see.

People who use polarised sunglasses for long stretches of time often say they are less tired than usual after hours of battling sun glare. Only polarised lenses can block out this dangerous, blinding glare. It can take 6-7 seconds to adjust to glare and becomes progressively worse as you age.

If glare impaired your vision for just three seconds whilst driving at 30mph, you would travel blind for 132 feet.

We stock a full range of polarised sunglasses in all our practices. Our experienced dispensing opticians can fit a frame to your shape, reduce glare and give clear vision.
