Hi, I see other people have answered your question. They are yellow tinted and dull the glare and allow you to see despite the glare. As others mentioned they are not perfect but they allow you to maintain a level of visibility that you would not have otherwise. Mine were an impulse purchase from Walgreens so I know I paid more than I should have. They were $20. You can probably get them cheaper and in a better style. Mine are unabomber style with yellow tint.... but it's dark when I wear them. Lol
