SPECIAL FOCUS Health& Safety lightweight fit with even weight distribution. Injection-moulded hard and soft components around the brow, nose and on side arms not only increases comfort but ensures eyewear stays put. Adaptable features such as lens inclination and extendable side arms allow wearers to achieve the ultimate close fit (to keep hazards out) and find a position that means they can work comfortably, confidently and with as little distraction as possible. Lens optical quality reduces eye strain, fatigue and headaches (optical class 1). Lenses with excellent optical quality are free of aberrations and imperfections – allowing the wearer to see using as close to natural vision as possible. Low-quality safety eyewear can result in poor optical clarity, one of the biggest factors in eye fatigue due to tiny distortions in the lens. The type of environment in which the work is undertaken should influence the lens shade(s) selected. For example, are employees working indoors under harsh, bright lights? Are people frequently moving between indoors and outdoors, between light and shaded areas or are they working outside in the sunshine where the intensity of the sun can be a hazard in itself? The selection of lens tint that is right for the environment together with the highest quality of lens engineering and performance all positively affects compliance. Compatibility with other PPE such as respirators, hearing protection or helmets should also be taken into consideration. Let’s talk about fogging Due to the way that safety glasses or goggles should fit, close to the head keeping dirt and debris out, it can cause moisture build up, especially if the wearer is doing a physical job which can result in the lens fogging. How you choose which coating you need depends on the environment and the application being performed. Some coatings offer anti-fog performance on the inside, where it is most needed, and a scratch-resistant hard coat on the exterior of the lens. Others are anti-fog and scratch resistant on both sides making them suitable for environments with high humidity. However, not all anti-fog coatings are created equal. The tests conducted for the coating performance are optional tests for manufacturers, requiring the anti-fog coating to perform for a minimum of 8 seconds on first use. Where many coatings fail is in the longevity of the anti-fog performance. Traditional hydrophobic anti-fog coatings are soap-based, washing off after a handful of cleans, making the eyewear ineffective and unusable. As soon as lens coating performance diminishes, employees try to compensate and compliance drops rendering the eyewear useless. Therefore, it is important to look out for manufacturers of permanent hydrophilic coatings that have been bonded onto the lens and last the life of the eyewear. When ‘wearability’ is designed into safety eyewear, employees are more likely to keep it where it should be, on their face and in front of their eyes. It is possible for employees to have high-performing, comfortable, properly fitted specs or goggles that keeps dust and debris out, in a style and design to ensure there is something for everyone.
