Will yellow glasses stop me being blinded? Will yellow glasses stop me being blinded ?

In the winter I commute along a canal path, the lights from the other cyclists are blinding at times.

Will yellow glasses stop this, it's too dark for normal sunglasses?
No. What blinds you is the relative brightness of the bike lights and the fact that unlike legal car lights, many of them are pointing straight at your face.

The yellow lenses are designed to increase contrast in daylight. They work by blocking blue light, which is scattered so that it comes from all directions and makes shadows less visible.

EDIT: The spectrum of most white LEDs does have an intense spike at blue wavelength. Most of the energy is still at longer wavelengths, where yellow glasses do not do much. They will also filter your own headlight and street lights if they are white LED variety. Because of Purkinje effect, the blue part of spectrum is more important for low light vision. This is why white LEDs seem disproportionately bright and why yellow glasses restrict your vision more in dark than during the day.
