Purchasing a new pair of stylish sunglasses is easy, most people pick the expensive brands that 'look the best', but have you ever checked EN conformity or considered what lens colour is the most suitable for a pair of holiday sunglasses? Probably not, and that's because the risks associated with leisure are slim.
However, when it comes to safety glasses; the environment, lens colour, lens coating and EN conformity are detrimental to the users' safety, comfort and ability to work. In this blog, we're going to explore the different lens colours available in Pyramex Safety Eyewear and the environments best suited.
What are the most popular lens colours?
Clear Lens Safety Glasses
OK, we know we've started boring, but there's a reason clear safety glasses are our most popular choice. Allowing 92% light transmission, Pyramex clear lenses offer the highest visibility out of all glasses. Blocking out 99.9% of UVA/UVB light, clear lenses are best suitable for general purposes indoors.

Grey Lens Safety Glasses
Next up; grey lenses. In comparison to clear lenses offering 92% light transmission, grey lenses come in much lower, at only 23% visible light transmitted. Grey lenses are much more suitable for working outdoors, particularly in bright sunlight, offering protection from excessive glare, along with UVA/UVB protection. Not so suitable for working indoors, as visibility would be hindered in dark environments.

I/O Mirror Safety Glasses
Finally, we have I/O lenses (Indoor/Outdoor); as the name suggests, these safety glasses are perfect for users who are frequently moving from indoors to outdoors and vice versa. Allowing 50% light transmission and reducing glare, these lenses offer good visibility in both environments, and also help the eyes adjust to different lighting conditions.

While we have provided three options; working indoors, outdoors, or a mix of both, it's important to note that these might not necessarily be the best fit. In one of our blogs, we discuss what to consider when selecting appropriate safety eyewear. As an example, Pyramex also offer an Amber lens. Similarly to clear lenses, Amber lenses are also very popular for indoor use, but help enhance contrast if the environment is poorly lit. Assessing the environment and risks is critical in specifying appropriate PPE, especially safety eyewear.
