This product works great.
I use this product for driving at night in a rural area of South Carolina because there is the ever present danger of hitting a deer crossing the road.  I have found that my vision is improved when using these glasses and the lights of oncoming automobiles are not as distracting.  I bought two pairs and gave one to a friend who drives a tour bus and he can't say enough about the benefit he has noticed while using this product.  I heartily endorse these glasses.
