Brown tint improves contrast by blocking out blue light. Unlike blue blocker lenses, it's available for a wider choice of lens materials and reduces bright sunlight when outdoors. It works well for seeing birds, baseballs, and other objects silhouetted against the sky. Brown works well for any outdoor situation where better perception of texture, such as grass-blade orientation on golf courses or snow surface texture when skiing, is important.
Use an Anti-Reflective Lens Coating for Reduced Glare and Better Night Vision
An anti-reflective (AR) lens coating prevents light behind and above you from reflecting off the inside of your glasses and into your eyes. Headlights of cars behind and beside you, windows, lights and lamps inside a room, or overhead sunlight can reflect back into your eyes and interfere with normal vision. Because less light reflects from the front of your lenses, more gets through to your eyes, which improves night vision. Light reflection is especially acute with high index lenses, and safe driving isn't possible without an AR
