Your Lenses and UV Radiation
- What are the risks of UV radiation?
Protecting your eyes is just as important as protecting your skin. The risks are real: UV rays are invisible to the naked eye but are present all the time, even in cloudy weather. Systematically failing to protect your eyes can cause problems in the long term such as keratitis (a chronic disease of the cornea) and early cataracts (opaqueness of the crystalline lens that can lead to total or partial blindness). Wearing protective eyewear, either sunglasses or regular glasses, is therefore recommended to protect your eyesight.
What are the criteria for good UV protection?
UV protection depends on the material used to make the lens, not its tint. An un-tinted lens can therefore provide 100% UV protection. Sunglass lenses do not always offer the necessary protection just because they are tinted. Tinting reduces brightness but does not stop UV rays. Effective protection means choosing a material that filters 100% of UVA and UVB.
- For sport
Certain lenses are particularly suitable for playing sport. They offer better, sharper, more comfortable vision and therefore help to improve your performance. These are mainly polarised lenses, photochromic (variable-tint Transitions) and polycarbonate lenses. Their specific added value can really change your vision. But be careful: not all lenses are suitable for all sports.
Follow our advice!
- Transitions variable-tint lenses
Transitions variable-tint lenses are suitable for sports where you repeatedly move in and out of shady and bright environments, such as mountain biking in a forest, or running. The wearer can therefore keep their sunglasses on, knowing that they have continuous protection from UV with the right tint for the conditions.
Transitions variable-tint lenses are also recommended for open-air sports played in variable conditions, such as tennis, running, golf, etc. The transition from cloudy to sunny conditions is smooth, and the wearer is untroubled by any change in the weather.
- Polycarbonate lenses
Polycarbonate lenses, made from an extremely impact-resistant material, offer the best level of shock resistance.
These lenses are ideal for sports with a high risk of a fall onto a hard surface, such as mountain biking or roller blading. The extreme resistance of the material ensures optimal protection from small stones being thrown up and potentially damaging the lenses.
Polycarbonate lenses are also recommended for shooting and hunting (protecting against the risk of recoil, being knocked by an elbow, the impact from a bullet, etc.).
