POLARISED SUNGLASSES
Polarised sunglasses help reduce certain distracting reflections, such as those from water and road surfaces. This guide explains how they work and what to consider when choosing frames and lenses.
Polarisation, UV protection and filter category are different characteristics. Check the manufacturer information, lighting conditions and intended use when choosing sunglasses; an Isolani optical centre can help you assess a suitable model.
What does ‘polarised’ mean?
polarised lenses incorporate an optical filter that blocks horizontal reflected light, which is responsible for glare on surfaces such as water, snow, glass and tarmac. This provides a clearer view, with natural colours and superior contrast.
Polarising technology is particularly useful in very bright environments, where reflected light can impair the perception of detail and cause eye strain.
Benefits of polarised lenses
Polarised sunglasses offer tangible benefits in everyday life:
• drastic reduction in glare
• greater clarity and contrast
• more natural colours
• reduced eye strain
• enhanced safety whilst driving
For those who spend a lot of time outdoors, they represent an advanced and highly comfortable solution.
When to choose polarised sunglasses
Polarised sunglasses are particularly suitable for:
• driving, especially on wet tarmac or on very bright days
• outdoor sports such as cycling, running, hiking and sailing
• activities near water or snow
• those who suffer from light sensitivity or glare
• those who want a more relaxed and natural view
For everyday use, polarised sunglasses are a versatile and practical choice, suitable for both men and women.
To understand the benefits and limitations of the different options, you can read our comparison between polarised and standard lenses.
How to choose the right model
The choice of model depends on how you’ll use them and the shape of your face. For driving, wraparound frames with dark lenses are recommended; for sport, lightweight and stable models; for everyday use, fashionable designs with certified polarised lenses.
To find the ideal size, please consult our Size Guide. At Isolani Opticians, we offer a selection of polarised glasses with high-quality lenses and frames designed to ensure comfort and protection in every situation.

Frequently Asked Questions
Do polarised lenses protect against UV rays?
Polarisation alone does not guarantee UV protection: it reduces certain reflections of visible light. Protection against UVA and UVB rays is a separate characteristic that should be checked in the manufacturer specifications. Choose sunglasses with declared UV protection and ask your optical centre if you are unsure about the lenses.
Are polarised sunglasses better for driving?
Yes. By reducing glare from the road surface and windscreens, they improve visibility and safety whilst driving.
Are polarised lenses suitable for sport?
Absolutely. They are ideal for outdoor sports such as cycling, running, hiking and sailing, thanks to their ability to reduce glare and provide high contrast.
How can I tell if a lens is polarised?
You can check this through specific in-store tests or by observing the reduction in glare on very bright surfaces. At Isolani Opticians, we can carry out an immediate check.
