This visor helps so much for night driving. I have not been able to drive at night due to the glares off headlights but now with this I can. This totally takes the glare off the oncoming lights. I cannot drive without it. I drive a convertible bug and this Ifits easily on the visor. I don't use the daytime one too much since always wearing sunglasses but it does work as well. I recommend this for anyone who has a hard time driving at night because of light glares.
