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.

Disadvantages of bifocal glasses

The disadvantage of bifocal glasses is that the different areas are clearly spaced and the appearance is not beautiful. The medium distance is fuzzy, and the adaptation period is needed, there is a prismatic jumping phenomenon. The focal distance between the upper and lower lenses is different, with a clear dividing line. The main disadvantage is that when the line of sight moves from far to near, there will be interference like jumping, and the middle distance object image is blurred.
