Your Eye Health Matters — Brought to You by ROYALTAIL
Sunglasses are a staple in every wardrobe. They elevate your look, shield you from glare, and reflect personal style. But beyond aesthetics, there’s a crucial reason to wear them: UV protection. Without proper UV shielding, even the most stylish shades can leave your eyes vulnerable to long-term damage.
At ROYALTAIL, we don’t just design fashion-forward sunglasses—we craft eyewear that protects your vision for years to come. In this guide, we’ll walk you through everything you need to know about UV protection in sunglasses, why it matters, and how ROYALTAIL ensures you’re covered in both style and safety.
What Is UV Radiation?
Ultraviolet (UV) radiation is a type of invisible light emitted by the sun. There are three main types:
-
UVA: Penetrates deep into the skin and eyes; associated with aging and long-term damage.
-
UVB: Can burn the skin and cornea; a major contributor to eye conditions like cataracts.
-
UVC: Blocked by the ozone layer and generally not a concern.
Unprotected eyes are highly sensitive to UVA and UVB exposure, which can cause immediate discomfort and long-term harm.
What Is UV Protection in Sunglasses?
UV protection in sunglasses refers to the lens’s ability to block out 100% of UVA and UVB rays. This is often labeled as UV400, meaning the sunglasses block all light rays with wavelengths up to 400 nanometers—including all UVA and UVB rays.
✅ ROYALTAIL Guarantee: Every pair of ROYALTAIL sunglasses is built with UV400 lenses for full-spectrum protection, certified and tested to meet international safety standards.
Why UV Protection Matters for Your Eyes
Most people understand the importance of sunscreen for skin. But your eyes need just as much protection—if not more. Without proper UV filtering, prolonged exposure can lead to serious conditions such as:
-
Photokeratitis (Sunburned Eyes) – Caused by intense UVB exposure
-
Cataracts – Clouding of the eye lens, often due to UV exposure over time
-
Macular Degeneration – Damage to the retina that can result in vision loss
-
Pterygium (Surfer’s Eye) – A growth on the white of the eye, common in UV-heavy environments
Protecting your eyes with UV-blocking sunglasses significantly reduces the risk of these conditions and keeps your vision healthy long-term.
How to Know If Sunglasses Offer True UV Protection
Not all sunglasses labeled “UV protection” offer adequate shielding. Here’s how to ensure you’re getting genuine protection:
✔ Look for "UV400" Marking
This indicates the lenses block 100% of harmful UVA and UVB rays.
✔ Buy From Reputable Brands
Cheap sunglasses may offer dark lenses, but they don’t always include UV protection. In fact, dark lenses without UV filtering can dilate pupils and increase UV damage.
✔ Polarized ≠ UV Protection
Polarized lenses reduce glare, but not all polarized sunglasses offer UV protection. Make sure you check for both.
✔ Choose Certified Products
All ROYALTAIL sunglasses undergo third-party testing to ensure UV compliance and optical quality.

Who Needs UV Protection the Most?

-

-
❄️ Snow & Water Enthusiasts – Snow and water reflect up to 80% of UV rays

👁️ Contact Lens Wearers – Need an extra layer of physical protection
