Vision Sir Sunglasses Yellow

THE LENS COLOUR determines how much light will pass through a lens. To keep vision optimal, you need less light in sunny conditions and more in cloudy weather.

Brown - A superb all-round constant density lens. It provides the best combination of true colour transmission and contrast. The optimal performance is achieved in medium bright to bright conditions.

Yellow - These lenses work as light enhancers. Good for dusk and low light as well as for overcast days and evenings.
