How to choose sunglasses

Every time the sun starts shining brightly, we rush to buy our sunglasses—but not all of them offer the same protection, nor do they suit everyone equally well.

Choosing the right pair isn’t just about following the latest trend. It’s important to consider protection, comfort, and how well they fit your face shape.

What may seem like a simple accessory can actually make the difference between protecting your eyes or unknowingly damaging them forever.

In this step-by-step guide, you’ll find all the key points to help you choose the trendiest sunglasses for this summer—with no mistakes.

Sun Protection Comes First—Even for Your Eyes

Before thinking about colors, shapes, or brands, you should know that UV protection is the most important factor.

Sunglasses must filter ultraviolet (UV) rays, which cause cumulative and irreversible eye damage.

A pair of sunglasses labeled with UV400 protection blocks 100% of UVA and UVB rays—an essential marker of quality.

Sunglasses sold in the EU must also carry a certification mark that guarantees the product was manufactured under minimum safety standards.

Types of Lenses and Filters in Sunglasses

Not all lenses offer the same level of protection or are suitable for the same lighting conditions. Their filtering capacity is categorized from 0 to 4:

• Category 0: Very light lenses, only suitable for indoor use.

• Category 1: Ideal for overcast days.

• Category 2: Suitable for moderate light, perfect for urban use.

• Category 3: Designed for sunny days—ideal for driving or walking in intense sunlight.

• Category 4: For extreme light conditions such as snow or high altitudes. Not recommended for driving.

Which Frame Shape Suits Your Face Best?

Choosing sunglasses that suit your face is also important—it lets you showcase your favorite style while enhancing your natural features.

• Round face: Square or rectangular frames help define the face.

• Square face: Round or oval frames soften sharp angles.

• Oval face: A versatile face shape that can pull off almost any style.

• Long face: Oversized frames or thick temples help focus attention on the upper part of the face.

• Heart-shaped face: Thin frames or aviator-style glasses work best to balance out the top of the face.

How to Choose Sunglasses Based on Material

Sunglasses can be made from a variety of materials: plastic, acetate, metal, or even wood—each with its own pros and cons.

• Acetate: Lightweight, durable, with matte or glossy finishes.

• Metal: Sleek, minimalist, and long-lasting—perfect for elegant styles.

• Plastic: Budget-friendly, though quality can vary—some are sturdy, others more fragile.

• Mixed materials: Combine different components to improve durability or enhance specific design features.

Which Lens Color Is Best?

Lens color isn’t just about aesthetics—it also affects how light is filtered and how well you can see under different conditions:

• Gray: Reduces glare without distorting colors—one of the most versatile options.

• Brown or amber: Enhances contrast, great for driving and outdoor sports.

• Green: Softens light while preserving natural colors, ideal for most outdoor activities.

• Yellow or orange: Improves visibility in low-light settings—not suitable for strong sunlight.

• Mirrored lenses: Reflect sunlight, ideal for bright environments and add a trendy look.

Practical Tips Before Buying

• Don’t judge by price alone: High-quality sunglasses aren’t always the most expensive. Always check for UV protection and CE certification.

• Choose polarized lenses for driving or sports: They reduce glare on water or asphalt, improving comfort in high-reflection environments.

• Trust your face shape: The best-fitting sunglasses are the ones that highlight your natural features.

• Follow your personal style instinct: The trendiest pair may not match your look—go for sunglasses that add a unique touch to your everyday style.

• Trends may change, but some styles are timeless: Aviators, wayfarers, cat-eye, and rectangular frames never go out of style.
