This item was first given to me as a Christmas gift 2017.  Day or night, they work beautifully! Cataracts tend to create a star-shaped brilliance that is piercingly painful to the eyes, and the immediate reaction is to close them.  Not ideal when driving. These lenses make it possible to see clearly under all/any driving conditions day/night; lightweight to perfectly fit over my prescription glasses. Ordered a second pair in case anything happens to my first set.
