Why you need polarised lenses for boating, sailing and watersports

Polarised sunglasses were first invented by Polaroid in 1935. It’s why a lot of people still use the term ‘Polaroid lenses’ when then mean ‘polarised lenses’.

Polarised lenses are different to standard sunglass lenses; they have a special film either sandwiched between two other layers of the lens or applied to the front of a lens. What this special film does is eliminate glare reflected off a surface like a pavement, road, snow or water.

Lightwaves from the sun travel in all directions but when sunlight strikes a surface like water it becomes concentrated – this polarised light as it is called causes glare. Non-polarized sunglasses only reduce the amount of light entering the eye; they don’t block glare. Polarised lenses block glare and allow only useful vertical light to enter so you can see much more clearly.

Glare makes it difficult and uncomfortable to see and can cause eye strain. It also distorts the true colour of objects and makes them harder to distinguish. With polarised sunglasses you get glare-free vision, clear contrasts, more natural colours and reduced eye fatigue. Because prolonged exposure to glare on the water causes eye strain it can in turn lead to headaches – another reason why watersport enthusiasts should wear polarised lenses.

Glare also causes a mirror-effect on water.  As a polarised lens will eliminate glare on the water it means you can see down below the surface. This will be especially useful for sea fishing. The popular polarised lens colours for boating & sailing are:

Grey – Good for bright / strong sun conditions.

Brown – Another good colour for bright sunny weather but adds contrast and helps sharpen the field of vision.

Amber – Also adds contrast and ideal for mixed weather and overcast conditions.

Yellow & Yellow-Amber – High contrast colours ideal for dull conditions and low / poor light.
