Not all sunglasses lenses are the same: each type offers specific features in terms of protection, visual comfort and aesthetic appeal. In this guide, discover the differences between UV400, polarised, mirrored and photochromic lenses, with practical advice on choosing the solution best suited to your needs.
At Centri Ottici Isolani, we select certified, high-quality lenses, designed to guarantee total UV protection and clear vision in all light conditions.
UV400 lenses
UV400 lenses offer the highest level of protection against UVA and UVB rays, blocking 100% of harmful radiation. They form the basis of any high-quality pair of sunglasses.
Benefits:
• total protection from UV rays
• prevention of eye strain
• safety for sensitive eyes and children
You can find out more about UV protection in the section dedicated to Prescription Lenses.
Polarised lenses
Polarised lenses eliminate glare from surfaces such as water, tarmac and glass, improving contrast and clarity. They are ideal for driving, sport and outdoor activities.
Benefits:
• reduced glare
• more natural colours
• greater safety whilst driving

photochromic lenses automatically darken in sunlight and return to a clear state indoors. They are perfect for those who frequently move between shaded and very bright areas.
Benefits:
