One of the questions we are asked from time to time is why we don’t put the lens ‘category’ in the description for each model. It’s partly because not all our brands provide this information and in reality almost all brown and grey (or ‘smoke’) lenses are Category 3. Primarily, sports sunglasses categories signify the density of the lens tint and there are 5 categories in total:
Category 0 is a clear or very light tint lens – mainly used for impact protection. Many Safety Eyewear glasses have a clear lens.
Category 1 is typically a yellow or pale / light tint. Not ideal for sunny conditions but OK in overcast skies.
Category 2 is typically the orange, rose, blue and red lenses. Fine for partially sunny conditions giving a good amount of protection against sunglare.
Category 3 is for strong sunlight and the most common category because almost all brown and grey (or ‘smoke’) lenses are Category 3. Shop leisure style sunglasses.
Category 4 is typically a very dark grey or brown lens – ideal in mountains or desert where the sun is intense and there are high glare conditions. See our Category 4 sunglasses. They are not to be used when driving as the density of tint can make it dangerous to do so. All the Category 4 sunglasses we sell are clearly described as such.
It’s important to recognise that the tint or colour has nothing to do with UV protection – the UV filter applied to lenses is actually clear so even a clear lens can be UV400 rated (the maximum protection from UVR). Every single sunglass or eyewear model that Sunglasses for Sport sells on the website is UV400 rated.
