I use these as night driving glasses to reduce glare and starry headlights.  I've been satisfied and feel that 3 pair are a good value.  I keep one in each vehicle and gave 1 away to my parents to try.  Had delivery issues with the original purchase - but one quick phone call to the seller and the issue was resolved easily.  Glasses seem pretty durable (metal frames with spring-hinged legs) so I think I'll have them for a while.  They are supplied with a soft bag that is used to clean the lens.
