Although lengths may range from 120 to 150 mm, there are some common industry standards:135, 140, 145, and 150 mm. The temples are long enough to extend beyond your ears, so the ends can be changed to match the contours of your head behind your ears.

You can choose driving goggles.
The goggles partly filter the far-light from the car. Products sold online include glasses with yellow lenses and yellow translucent shades that clip onto car shades. Shades block out oncoming far-light, while glasses prevent rearview mirror glare from vehicles behind. Most of the light emitted by car headlights is short-wavelength ultraviolet and blue light. The yellow polyester blocks them while allowing the longer wavelengths of red and green light to pass through, making the headlights softer when seen through the goggles without reducing the brightness of the road and the surrounding environment.
