🕶 How to Choose the Best Wide-Fit Sunglasses to Protect Your Eyes

Why UV Protection in Sunglasses Matters

The sun’s UV rays don’t just damage your skin—they also harm your eyes. Prolonged exposure can lead to serious conditions like:

• Cataracts – Clouding of the eye lens that can impair vision

• Macular degeneration – A leading cause of vision loss in older adults

• Photokeratitis – Essentially a sunburn on your cornea, causing pain and blurred vision

Even on overcast days, UV rays penetrate cloud cover—so eye protection is a year-round necessity. Snow, sand, and water can all reflect sunlight, intensifying your UV exposure without you even realising it.

That’s why UV protection sunglasses aren’t just a style choice—they’re a health essential. But not all sunglasses are created equal. Pricey designer shades don’t always offer proper protection, and many cheap high-street options skip key features like polarisation or full-spectrum UV filtering.

Are Polarised Lenses the Same as UV Protection?

Not exactly. Polarisation cuts glare, especially from reflective surfaces like water, snow, windshields, and roads—but it doesn’t automatically mean UV protection.

Many low-cost sunglasses are polarised, but lack proper UV blocking technology. That can give a false sense of safety, because your pupils dilate behind the darker lenses, letting in more harmful rays if UV protection is missing.

That’s why all Faded Days lenses are both polarised and UV400 certified. You get the best of both worlds: clear vision and total protection.

Our Picks: Best UV Protection Sunglasses for Wide Faces

Here are the best wide face sunglasses that combine eye protection and fit.

What to Look For in Sunglasses with the Best UV Protection

When shopping for the best UV blocking sunglasses, make sure they tick these boxes:

• UV400 protection – Blocks 100% of UVA and UVB rays

• Polarised lenses – Reduces glare and improves clarity (especially around water, snow, or glass)

• Full lens coverage – Bigger lenses = better shielding

• Wraparound or wide styles – Protects peripheral vision from side exposure

Think of UV400 as your shield—it’s the highest standard available, and it guarantees that your eyes are fully protected. Look for certification or product detail listings that explicitly confirm UV400 compliance.

At Faded Days, every pair comes with UV400 lenses as standard—so your protection is guaranteed, no matter which style you choose.

What Is the Best UV Protection for Sunglasses?

UV400 is the gold standard. It blocks both UVA and UVB rays, which are the most harmful forms of ultraviolet light.

Don’t be fooled by darker lenses—lens colour doesn’t equal UV protection. Only lenses marked UV400 (like all Faded Days lenses) guarantee maximum safety.

You should also beware of labels like "UV-resistant" or "blocks most UV rays"—these vague terms aren’t enough. Always look for a clear UV400 or 100% UVA/UVB statement.
