Not all sunglasses are equal
With the right pair of sunglasses, you’ll be equipped for any outdoor conditions. But not all frames and lenses provide the same guarantees. Discover how you can judge the performance of different sunglasses in terms of both protection and comfort.
Sunglasses give you confidence to make the most of your life outdoors. But you should be aware that not all sunglasses offer the same guarantees.
Each pair of sunglasses is composed of a type of lens and a specific frame. Lenses come in different materials, with a range of tints and technologies, while frames vary in materials, shape and design.
What makes sunglasses more comfortable?
One of the most important roles of your sunglasses is providing you with a comfortable visual experience. This means they should let you see clearly without straining your eyes – no matter what the conditions. It also means they should fit snugly on your face.
• Reducing sunlight intensity: tints, special technologies
The main way your sunglasses help your eyes against bright light is through the tinting of the lens. Tints are ranked in categories from 0 to 4 depending on their darkness. Lower ratings are for weak sunlight, while category 4 is designed for extreme sun conditions. Note that the tint is not responsible for UV protection; its role is to provide visual comfort. The lens may also use photochromic technology, meaning it automatically adapts its shading to the intensity of the light.
• Eliminating glare: polarized lenses
To eliminate dazzling glare, you should choose a polarized lens. Thanks to a special filter on the lens, polarized sunglasses do not only lower sunlight intensity; they also shield you from the discomfort of glare (More information on polarized lenses on Xperio web site).
• Choosing a comfortable fit: frame size and shape
The frame of your sunglasses should be a perfect fit for your face. Make sure the temples are just the right length and the shape suits the contours of your face. This is important not just for day-to-day use, but because the frame contributes to your visual comfort by blocking out light from the sides.
How well will my sunglasses protect me?
Beyond visual comfort, the main reason for wearing sunglasses is to protect your eyes from potential damage. Different lenses and frames will protect you to a greater or lesser degree.
• Mechanical protection: the material of your lens and frame
The material of the lens offer mechanical protection against impact. Polycarbonate lenses and frames, for example, are virtually unbreakable and therefore particularly well-suited if you play sports or do DIY, or for young children.
• UV protection: material and special lens treatments
What your lens is made from directly impacts its ability to absorb UV rays, with certain materials providing more UV protection than others. Extra protection can be gained by giving the lens a special treatment to protect fromblock UV more efficiently.

• Complementary protection thanks to the shape of your frame
The shape of the frame also plays a role in protection from UV and from external elements like dust and pollen, with certain frames being thicker or fitting more tightly to your face. Just as these designs help block out more visible light, they also protect against UV rays that could pass between the frame and your face.
As an example, wraparound frames, will be more efficient in lateral and overall protection as they usually perfectly fit on the face.
The potential combinations of lens and frame are endless, and each pair of sunglasses is designed to offer specific benefits depending on the user’s needs and lifestyle. For a better idea of how to choose a lens and frame that suits you, take a look at our online diagnostic tool.
