Tints: Available in Grey, Brown or Green. These are ideal for sunglass choice and are solid tints. They meet the Australian Standard for UVR Protection and include a hard multi-coat. Grey lenses provide a high degree of glare reduction and are suitable for bright light activities. Brown lenses enhance contrast on hazy or overcast days and are suitable for everyday use. We do not recommend you use any tinted lenses for driving at night, or in conditions of poor visibility where light is at a premium.
