Driving Sunglasses 101

If you seem to spend your life behind the wheel, you’ll know that sunglasses are an essential glovebox fodder.

As we’ve mentioned in a previous post, light acts differently when it reflects off flat surfaces like roads.

Instead of scattering in all directions it polarizes and travels in a uniform, horizontal fashion.

This creates a glare, which can be really unpleasant if you’re driving, causing you to squint and your eyes to get tired quickly.

Shades are important for any motor enthusiast.

But, did you know that not just any will do?

In fact, certain sunglasses are actually not suitable for driving.

Some glasses do not allow enough light in, decreasing visibility, while lenses of certain colours impact the spectrum that drivers can see, and the contrast they can distinguish.

Given this, here’s a two-part guide of things to think about when buying your new driving sunglasses.

Size & Style

Oversized sunnies are not a good option for motorists.

Anything that affects your peripheral vision and impacts your ability to miss things that are not in your direct line of vision are a big no-no.

Lots of people love Aviators when they’re hitting the road, and the flat profile and slimline temples do make them an attractive option.

A different style to choose would be one where the lenses wrap around the eyes slightly, to prevent any glare from the side.

Most importantly, make sure that your shades are comfortable and sit securely on your face. This will ensure you don’t have to fiddle with them or make any mid-journey adjustments.

Lens Colour

The lens colour of your sunglasses actually affects how well you are able to perceive certain colours, and the degree of contrast you are able to see.

This is important for drivers, as they need to be able see and interpret traffic lights and road signs, which are dependent on colours acting as signifiers in order to drive safely.

Pink, blue and green lenses should NOT be worn while driving – they can make distinguishing red lights difficult or impossible.

Only get driving sunglasses with lenses in these colours if there is a label on them saying they have been marked safe for driving, otherwise assume they are not.

Grey and brown lenses are best for drivers as they do not change the way that colours appear.

Some amber and yellow-toned lenses help enhance definition, but these are usually in sunglasses that have been specifically designed for driving.

Remember to get polarized lenses to help you deal with glare.

Tint Density

Tint density is also an important consideration, as it affects how much light can get through.

Even if two pairs of sunglasses have the same lens colour, they may let in different levels of light.

Different densities are suitable for different conditions, and it’s important to be aware of this.
