TECHTAL KUV - ULTRA VIOLETMEDIUM IMPACT CERTIFIEDInvisible rays of radiant energy with wavelengths that range between 200-400nm.UVA and UVB rays are considered harmful to your eyes and skin that can begenerated by solar or artiocial sources.Eye protectors that are tested and meet the Medium Impact requirementsof AS/NZS 1337.1 are examined and certioed by a third-party independentcertiocation body.Independent certiocation also provides manufacturers with an individual licensenumber, which signioes registration and waives an ongoing testing program toensure product production delivers a consistently high standard of quality andperformance.BLUE LIGHTHas a wavelength of between approximately 380nm-500nm. Although one of theshortest, its highest energy wavelength can damage the retina, cause eyestrain,fatigue and headaches. Main sources are sunlight, nuorescent and LED lighting,digital screens and electronic devices.IR - INFRA REDIR rays have a longer wavelength than visible light and are also known as heatrays. Long term exposure can lead to lens, cornea and retina damage.Main source - The sun and mechanically generated such as gas welding.NM - NANOMETERThe unit measure of a light wave. 1 nanometer = 1 billionth of a meter.UV385 LENSESFilter out 100% of UV rays up to 385nm and are mainly used in clear lenses.UV400 LENSESFilter out 100% of UV rays up to 400nm and are mainly used in tinted lenses.BASE LENSRefers to lens curvature and denoted by a numeral preox. Most wraparounddesigns would generally have a measured curve of 8 plus.MEDIUM IMPACTEye protectors that are tested to Medium Impact as per the requirements ofAS/NZS 1337.1:2010. This includes subjecting the eye protector to front-on aswell as side impact by using a 6 mm steel ball projected at a speed of 45m/sec(162km/h). The Medium Impact classiocation is the highest level of protectionthat can be given to eye protectors which includes goggles.SMART VUE (PHOTOCHROMIC LENS TECHNOLOGY)Photochromic lenses darken to a sunglasses tint when exposed to sunlight or UVultraviolet and return to a clear state when indoors, away from the sun9s rays.CO-MOULDEDThe bonding of two or more materials during the manufacturing processRx READYA spectacle frame that can be otted with prescription lensesPC LENSESPolycarbonate lenses are lightweight and up to 10 times more impact resistantthan plastic or glass lenses. They also provide up to 99.9% protection from UVrays and can be further treated with a series of coatings such as anti-scratchand anti fogFRAMESThe majority of our range consist of two main types of materials.1.
