How To Choose Sunglasses For Driving - Guide

It is important to choose the right frame and lens.

Some sunglasses are not suitable for driving. This is something that many drivers don't realize. Some sunglasses might not let enough light enter the eyes, which can impair visibility. Others may have a specific lens colour that negatively impacts the spectrum and contrast of colors distinguishable for drivers.

These and other factors are important to ensure that the driving sunglasses you choose won't increase your chances of getting into an accident. This guide includes information about frame and lens styles, tint densities and coatings, as well as safety markings.


Frame style

It's crucial to protect your peripheral vision from the sun while driving. Famous celebrities like Paris Hilton and Victoria Beckham have made over-sized frames a big problem. They can make it difficult to see the road ahead, making it more difficult to avoid accidents.

Large lenses and short arms such as those found in aviators are great for protecting your eyes from the sun. Wraparound styles can provide sun protection without blocking your vision.

You need to choose the right frame for your driving sunglasses. This is not only for safety but also to avoid being penalized in an accident where your sunglasses were involved. There aren't any guidelines regarding sunglasses frames. However, we recommend that you choose a style that allows you to see clearly from all angles.


Lens color

Different lenses have different effects on how much visible light can reach the eyes and how well the person can see certain colors. They also affect the visual contrast and how bright the colors are. The wrong lenses can have a negative impact on how well a driver sees road signs and traffic lights and can spot potential dangers.

Research shows that pink, blue, and green lenses are not recommended for driving. They can cause red lights to be difficult to distinguish. These shades are safe to drive, but sunglasses in these colors can be dangerous.

Grey and brown lenses with polarization are the best for driving sunglasses. They are neutral in color, so they don't alter the appearance of colors. Some sunglasses designed specifically for drivers include yellow-toned and amber-toned lense, which can enhance contrast and define.


Tint density

Whatever (safe!) you choose. Tint density is an important consideration, regardless of the color lens you choose. Tint density can be rated on a scale from 0 (clear), to 4 (very dark) and it is the most important factor in determining how much light can reach the eyes. For example, two pairs of sunglasses with similar density ratings, such as grey lenses, won't block the exact same amount of light if they have different densities.


You can see that 3-8% light transmission sunglasses, class 4, should not be worn behind the wheel. Class 0 is only useful for driving at night or on cloudy days. Driving with sunglasses that have an insufficient tint density or reduce concentration can lead to drowsiness and increase the likelihood of getting into an accident.


Driving and lenses that are light sensitive

Many people prefer to wear sunglasses that are light sensitive or 'photochromic'. These lenses see tint density changes depending on UV light exposure. However, Transitions or standard photochromic lenses are not recommended for car use. Windscreens can block up to 40% UV light, slow down the rate at which lenses change color and cause drivers to drive with inappropriate shades. They could be too dark or too light.



Graduated lenses

Graduated tints - which are road-safe colors and have a suitable tint density rating - are often preferred for driving. They have a darker tint at its top than it does at the bottom. You can still see the dashboard while being protected from the sun. Graduated tint works best when the sun shines high above the horizon, but it is less effective when the sun is lower on the horizon. This is because the tint density is further down the lens.


Polarized lenses

Drivers will love polarized lenses because they reduce the glare of headlights and reflect light off wet roads. You will feel more comfortable while driving thanks to the reduced strain on your eyes as well as UV protection. Polarized lenses are also useful in fogging or hazy conditions, as they can improve contrast and sharpen details.


Lens coatings

Specific lens coatings are a way to enhance the quality and durability of the sunglasses.

Lenses are polished to give them a smooth finish. However, this can reflect about 10% of the light that hits it. This is dramatically reduced by anti-reflective coating, which means that more light can be transmitted through the lens. This improves visibility. Anti-glare coating also repels grease and water, making it easier for sunglasses to be clean and clear.

Many eyewear manufacturers offer their own anti-glare coatings that are patented for driving sunglasses.

A scratch resistant coating protects your sunglasses from damage and extends their life. Scratches can cause lenses to become scratched by dirt and knocking on them. These scratches can increase glare which can greatly impact your vision.
