When shopping for sunglasses or eyewear, you’ve likely seen the term UV400 — but what does it actually mean, and why is it so important?
At Deluxe Sunglasses, every pair of our polarized shades comes with UV400 protection, ensuring your eyes are safe, stylish, and ready for any season.
In this blog, we’ll break down what UV400 means, answer some of the most commonly searched questions on Google, and explain why it’s essential for your eye health.
🔍 What Does UV400 Mean in Sunglasses?
UV400 means the lenses block ultraviolet rays with wavelengths up to 400 nanometers, which includes 100% of both UVA and UVB rays. These rays come from the sun and can cause long-term damage to your eyes.
✅ Bottom line: UV400 = complete UV protection for your eyes.
🌞 Why Is UV Protection Important in Sunglasses?
Even on cloudy days or in winter, UV rays penetrate the atmosphere. Prolonged exposure can lead to serious conditions like:
- Cataracts
- Macular degeneration
- Photokeratitis (sunburn of the eye)
- Skin cancer around the eyes
Wearing UV400 sunglasses helps prevent all of these risks.

💬 Popular Google Questions About UV400 – Answered
Is UV400 better than polarized lenses?
Not necessarily. Polarized lenses reduce glare, especially from water or pavement. UV400 blocks harmful UV rays. The best sunglasses have both.
➡️ All Deluxe Sunglasses are UV400 & polarized for full protection and visibility.
Are all sunglasses UV400?
No. Many cheap or fashion sunglasses don’t meet UV400 standards. Always check the label or buy from a trusted brand like Deluxe that guarantees it.
Do you need UV400 in winter?
