Sunscreen technology focuses on providing effective defence against ultraviolet (UV) radiation from the sun, which can be harmful to the skin and eyes.
Sun protection technology aims to provide a safe and comfortable visual experience, protecting the eyes from damage caused by UV radiation and improving visual quality in various environmental conditions.
A key aspect of protection is that sunglasses are equipped with filters designed to absorb or block harmful ultraviolet rays. UV filters are commonly classified into three categories: UVA, UVB and UVC. UVA and UVB are the most relevant to eye and skin health.
Polarised lenses are designed to reduce distracting reflections caused by sunlight reflecting off surfaces such as water, snow and pavement. This not only improves visual comfort, but also provides greater clarity and contrast. Also, anti-reflective and anti-scratch coatings reduce unwanted reflections and maximise light transmission through the lenses.
In addition to UV rays, some sunglasses are designed to filter out certain wavelengths of visible light, especially those considered potentially harmful, such as blue.
The choice of lens material can affect the quality of sun protection. Materials such as polycarbonate, as in the case of Paraffin, and polyvinyl acetate (PVA) are known to be lightweight and strong, as well as offering good UV protection.
Sunglasses are often classified into categories according to the amount of light they block. This ranges from lighter categories, suitable for cloudy days, to darker categories, ideal for bright sunlight conditions. All our glasses are certified category 3.
Sunglasses may also have specific designs for certain activities, such as water sports or snow sports, which require additional protection against glare and UV radiation. It is important that sunglasses comply with health and safety regulations, ensuring that they provide the protection advertised and are made from safe materials.
Sun protection technology continues to evolve. New materials and techniques are constantly being researched and developed to improve the quality, comfort and effectiveness of sunglasses.
