Currently on nightshift and just tested out my new yellow lens glasses for nightriding and they do work by cutting down on the glare of oncoming traffic, I no longer have to stare at my own light beam to stop from getting blinded by car headlights. Wish I'd tried these years ago. Clarity is a little worse and everything has a trippy yellow/green glow to it but the fact that they also cut out the cr*p that the cattle trucks throw up is also a bonus. I would recommend them to any regular night cyclists.
