Defence Model

The Defence model is one of the most popular models in our range thanks to its playful design, which immediately catches the eye. These glasses are not only stylish, but also highly functional, making them an ideal choice for everyday wear and special occasions.

One of the key features of these glasses is the standardised polarised sun filters at category 3. Polarisation is a technology that significantly reduces glare from horizontal surfaces such as water, snow or roads. This means that when wearing these glasses, you will have clearer and sharper vision, which is particularly useful when driving, playing sport or spending time near water. Category 3 rating means a high level of sun protection, which is ideal for bright sunny days.

Another important aspect of these glasses is their ability to maximally suppress UVA, UVB and UVC radiation. UVA radiation can penetrate deep into the skin and cause premature ageing, whilst UVB radiation is the main cause of sunburn. UVC radiation is the most dangerous, but most of it is absorbed by the atmosphere. However, it is important to have glasses that provide protection against all these types of radiation, so that your eyes are as well protected as possible.

The 3F brand is synonymous with quality and reliability. All our models, including the Defence model, are designed with maximum comfort and protection in mind. Our glasses are made from durable materials that guarantee long life and resistance to damage. Moreover, they are lightweight and comfortable, so you can wear them all day without discomfort.

The Defence model is therefore not only a stylish accessory, but also a practical tool for protecting your eyes. Whether you are on the beach, in the mountains or simply in the city, these glasses will provide you with the necessary protection whilst also offering a modern and playful look. 3F – that is what you want!
