Prescription Sunglasses Lenses
Nowadays, with technology growing, you'll notice that sunglasses aren't just available with one standard prescription lens. They now come with a choice of superior polarised lenses.
There are significant differences between the lenses. Some are obvious while others won't be noticeable until you have tried polarised lenses. When shopping for new prescription sunglasses, be sure to weigh up the pros and cons of both lenses. This will help you find the perfect sunglasses.
The Difference Between Standard & Polarised Lenses
Apart from being more expensive, polarised lenses differ from standard lenses in one main way. The vertical ‘polarisers’ block the transmission of horizontal light through the lenses, dramatically reducing glare. Glare can hit your eyes from the road, the bonnet or windscreen of a car, water surfaces, and any other horizontal plane the sun can reflect off.
The difference between the two lenses is very apparent when you hold them next to one another. Although a standard sunglasses tint will protect your eyes from UV rays, it will not reduce the glare. This can be extremely dangerous when driving in conditions where glare occurs. However, with polarised lenses, glare is reduced immediately. This allows you to see better and clearly distinguish the difference between lines and textures.
Why Consider Polarised Lenses?
Even if you buy a cheap pair of sunglasses frames, it is well worth investing in polarised lenses. Like many people who have tried polarised sunglasses, you will find that you may never go back to standard sunglasses.
When you're driving, the surface glare off the road and other cars can give you eye strain and make you drowsy. However, polarised lenses will block the glare making you feel more alert so you can pay more attention to your surroundings.
Polarised lenses are also very useful when taking part in outdoor activities, such as skiing, sailing, or fishing. The glare produced from the sun’s reflection on the white snow is difficult to eliminate with standard lenses. The same goes for the glare reflecting off the water's surface. Polarised sunglasses eliminate the glare making it much easier to see the true surface of what you are viewing.
Summary
With a non-polarised lens, your eyes will still receive protection from harmful UV rays. However, polarised prescription sunglasses will not only protect your eyes from UV rays, but also from any glare and reflections on those bright summer days.
All of our prescription sunglasses are available with polarized lenses by selecting the relevant options when customising your lenses.
