Damage is often spotted in eye exams and can contribute to vision problems.\r\nPhotochromic performance is influenced by temperature uv exposure and lens material and can vary among brands\r\nTransitions lenses provide UV400 protection, % reduction of 100 UVA and UVB ,helping to preserve your long-term eye health.\r\nUVA are the most prevalent and penetrating rays during all daylight hours throughout the year causing wrinkles, sun spots,skin cancer\r\nUVB causes more sunburn but more prevalent in the middle of the day\r\nUVC rays are absorbed by the ozone layer and generally don\u2019t reach the earth\u2019s surface. there are germicidal disinfectant uses of man-made UVC radiation such as in hospital settings.\r\n\r\nThere is a mandatory safety standard for sunglasses and fashion spectacles in Australia. Since 1 July 2019, all sunglasses and fashion spectacles, including uniformly tinted, polarizing, photochromic and gradient tinted lenses sold in Australia must be tested and labelled according to the Australian\/New Zealand Standard for Sunglasses and Fashion Spectacles (AS\/NZS 1067:2016 Eye and face protection: Sunglasses and fashion spectacles). \r\nFor outdoor workers, tinted eye protectors are available that meet the Australian standard for occupational eye protectors (AS\/NZS 1337 Personal eye protection: Eye and face protectors for occupational applications) and provide UVR protection and reduced glare outdoors. Untinted eye protectors marked 'O' also have sufficient UVR protection for outdoor use. Eye protectors are not assessed for their suitability for driving.\r\n\r\n ","link":"https:\/\/www.peterdarcy.com.au\/tag\/tints\/","name":"tints","slug":"tints","taxonomy":"post_tag","meta":[],"yoast_head":"\n
