![]() ![]() IR, just beyond the red end of the spectrum, is also invisible and harmful to us. Unfortunately this is a false assumption… it is not how dark or light the lenses are that determines their effectiveness in blocking these harmful uv rays, but rather the coatings applied to the lenses!” Infrared (IR) “Lens tint is sometimes confused with how dark the lenses are, and some people feel that the darker the lenses the more effective they are. Overexposure to UV light damages skin and eyes, which is why we wear sunscreen and sunglasses that block UV light.Īll quality safety eyewear and sunglasses block 99.9% of UV light regardless of lens tint. In addition to causing color distortion and potential eye strain and damage, blue light may also increase cancer risk and have connections to diabetes and obesity.” ( Benefits of Copper, Orange, Yellow and Brown Lens Tints) Ultraviolet (UV)īeyond blue light in the visible light spectrum is UV light. “More research is needed, but exposure to blue light clearly has a significant impact on general health. In addition, electronics like cell phones, TVs, and computer monitors emit blue light and can contribute to sleep deprivation. Prolonged exposure results in quicker eye fatigue than different types of visible light.īlue light also suppresses Melatonin, a hormone our brain releases to help us sleep. Because blue light scatters easily compared to other visible light, we have more trouble focusing on it. While we won’t go into detail on each type of visible light, blue light does deserve some attention because of its potential negative impact. That range starts with blue on one end and ends with red on the other, with yellow and green combining in the middle to make up the range most natural for us to see and process. If visible light is broken out through a prism, we can see a rainbow pattern showing the spectrum of light colors visible to us. Visible light, also called white light, makes up a relatively small range of light waves humans can see. ![]() General knowledge of visible light transmission (VLT) is also helpful. Specifically, having a basic knowledge of visible light (white light) and the two light ranges on either side of it on the electromagnetic spectrum, infrared (IR) and ultraviolet (UV). Understanding light exposure can help you understand the value of lens tints and how to choose the best color. Choosing the best lens tint depends on the environment and lighting conditions combined with the unique needs and preferences of the wearer. With a range of colors and gradients, every option holds specific purposes and benefits. From frame style and color to lens coating and safety standards, there’s exactly what’s needed for any situation. Today’s safety eyewear comes with seemingly endless combinations of features. ![]()
