Gentle Remind
The instruction about not suitable for driving at night or other low-light conditions for SUNGLASSES only, night vision glasses is for sure suitable for use at night or rainy day.
Night vision glasses cut about 10% to 20% glare from headlight depends on environment.
No such night vision glasses can block 100% glare of headlight because it is contrary to the theory of optics.
Transmittance demand of driving at night is not same as driving at day time.
If more glare are blocked the vision will be more dark, which is dangerous.
Just like gray color sunglasses can cut more glares but it will make the vision darken.
DUCO yellow night vision glasses will not only change light from white to yellow but also balance glare and vision, cut the glare and increase brightness.
It is surely better than naked eyes watching glare when drive in night.
It is also recommended to use for driving in rainy day or dusk.
