Driving to work today, all I could see was the low winter sun beaming into my eyes. This inevitably caused me to slow down, bring the visor down, and also to get my sunglasses on. Sunglasses, in the winter of all time! Luckily I use polarised sunglasses.
A polarised lens greatly reduces reflected glare from water or from other surfaces. The sun’s rays reflect light in every direction, so when a ray hits a flat surface, the reflected light shines back at your eye and is magnified, causing glare. The technology within a polarised lenses blocks out horizontal light waves, allowing the vertical light waves to reach the eye. The person looking through the lens can still see clearly through the lens, with reduced brightness and glare of light, maximising comfort and visibility for the user.
So who could benefit from this you ask?
- Light sensitive individuals, including post cataract surgery patients
- Individuals who are continually exposed to bright light through windows
- Individuals involved in fishing
Reduces reflections from the water surface, ie when fishing the individual can see the fish in the water.
- Individuals involved in water sports.
Basically, anyone who gets glare doing outdoor activities who has to deal with light coming from unwanted directions. The benefits of having polarised lenses are:
- Colour perception.
Colours appear bolder and brighter
- Enhanced clarity.
Better contrast, reduced glare and less stress on the eyes results in an overall better clarity of vision.
- Better contrast
Because glare is blocked, contrast is enhanced vision, which results in better safety for outdoor activities.
- Reduced eye stress.
Since the harmful light rays are blocked and what you see is enhanced, your eyes won’t have to work as hard.
Of course, the other option is to have tinted lenses. They’re not bad either, they’re good for reducing brightness and blocking UV, but they don’t eliminate harsh glare in the way that polarised lenses do
So who do we not recommend polarised lenses for?
- Pilots, the polarised lenses may interfere with the various screens which a pilot uses within the aircraft. Can also make other airplanes less visible.
- Skiers who ski down steep slopes, the polarised lenses will reduce the visibility of potentially harmful ice patches on the slope.
Now to park up, have a lovely coffee, and start my day in an artificially lit room, away from the winter’s light.
