What Is So Special About A TAC Lens?
TAC Lens Technology
TAC (Tri-Acetate Cellulose) polarised lenses are formulated with advanced lens technology to provide superior visual clarity and polarisation. They are coated for scratch resistance and offer 100% protection against harmful UV rays up to 400 nanometers. These lenses are lightweight and highly impact-resistant, making them an excellent choice for general use, outdoor activities and even sports.
Each lens is comprised of a number of layers:
What Are Those Protective Coatings For?
Our sunglasses are designed with both durability and safety in mind. So we've utilised a lens technology that is also highly impact-resistant. In fact, our TAC polarised sunglasses can even withstand being run over by a car. So, if they can handle that level of stress, you can trust that they'll hold up to the rough and tumble of everyday life.
What Does The UV400 Filter Do?
Our TAC UV400 lenses are designed to provide the highest level of protection against harmful ultraviolet (UV) radiation from the sun. The "400" in UV400 refers to the wavelength of light that the lenses can block, specifically up to 400 nanometers. This includes both UVA and UVB rays, which are the most damaging to our eyes.
The lenses are coated with a special filter that absorbs and blocks UV radiation, preventing it from reaching the eyes. This is especially important because UV radiation can cause a range of eye problems, including cataracts, macular degeneration, and corneal damage. By wearing sunglasses with UV400 lenses, you can enjoy the outdoors while protecting your eyes from harmful UV rays.
Why Is This Even More Important For Kids?
Up to 50% of lifetime UV damage to the eyes occurs before the age of 10 and is irreversible, leading to potential long-term ailments. That is why it is so important to protect children's eyes with sunglasses that have TAC polarised UV400 lenses.
