Distinguishing genuine sunglasses from counterfeit models is essential to protect your eyesight and ensure quality, safety and durability. In this guide, find out how to distinguish a genuine product from a counterfeit, which details to check and why you should only buy from official retailers.

At Centri Ottici Isolani, we exclusively stock genuine sunglasses sourced from certified channels, complete with a warranty, official packaging and guaranteed UV protection.

Why it’s important to choose genuine sunglasses

Counterfeit sunglasses may look similar to the originals, but they do not offer the same quality or protection. Uncertified lenses can cause eye strain and distortion, and do not guarantee the necessary UV protection.

Genuine glasses, on the other hand, meet high safety standards, use high-quality materials and guarantee clear, comfortable vision.

1. Check the UV protection

Genuine sunglasses always offer certified UV400 protection. Counterfeit models often bear generic or unverifiable labels.

You can check the UV protection at our Opticians’ Centres using professional equipment.

2. Check the quality of the lenses

Genuine lenses are uniform, clear and free from distortion. Counterfeit ones may exhibit:

• abnormal reflections
• lateral distortions
• uneven colouring
• poor scratch resistance

For further information, please refer to the section dedicated to Ophthalmic Lenses.

3. Check the frames

Genuine frames are made from premium materials such as acetate, lightweight metals and technical polymers. Counterfeit frames often use cheap, flimsy plastics.

Signs of counterfeiting:

• smudged or misaligned lettering
• fragile hinges
• too light or too heavy
• uneven finishes

4. Packaging and certifications

Genuine glasses always include:

• official case
• branded cleaning cloth
• CE certification
• manufacturer’s warranty

At Isolani Optical Centres, every pair of glasses comes with official documentation and a full warranty.

5. Where to buy genuine glasses

To avoid counterfeits, it is essential to buy only from authorised retailers. Our Isolani Boutique offers a selection from the most prestigious brands, whilst the E-shop features the most sought-after and certified models.
