Can night driving glasses prevent blue light?

Night driving glasses are called night vision goggles. Some night-driving glasses have anti-reflective coatings. Night driving glasses reduce glare by scattering and filtering blue light. Blue light is the shortest wavelength in the spectrum and is possible to cause glare when it enters the eye.

But tests and studies have shown that night driving glasses don't improve night vision or help drivers see pedestrians faster than they won’t wear them.
