When shopping for sunglasses, you’ll see two terms pop up often: polarized lenses and UV-protective lenses. While both offer important benefits, they serve very different purposes. At Adair Eyewear, we work with clients every day who want high-end sunglasses that not only look refined, but also protect their eyes in the ways that matter most.
This guide will walk you through the key differences between polarized and UV-protective lenses, so you can make an informed decision about what to wear and why. Whether you’re headed out on the water or simply driving across town, the right lens makes a noticeable difference.
What Are Polarized Lenses?
What’s the main purpose of polarized lenses?
Polarized lenses are designed to reduce glare. Glare happens when light reflects off flat, reflective surfaces such as water, glass, sand, or pavement. That intense brightness can distort vision and cause eye strain, especially during outdoor activities.
How do polarized lenses work?
These lenses contain a special filter that blocks horizontally oriented light waves while still allowing vertical light to pass through. Imagine it like a window blind that narrows the direction of light, helping your eyes process clearer, more accurate visuals.
Benefits of Polarized Lenses
- Reduces eye fatigue during long exposure to bright light
- Improves contrast and sharpness in high-glare environments
- Ideal for activities like boating, fishing, skiing, and driving
- Enhances depth perception and color definition in sunlight
Are there any downsides to polarized lenses?
While incredibly effective for glare reduction, polarized lenses may make certain LCD screens harder to see. That includes car dashboards, ATMs, and phone screens. In some cases, they can also reduce visibility of icy patches on roads or slopes.
Brands at Adair Eyewear that offer polarized lenses:
These brands are available through our boutique and can be fitted with custom prescription lenses if needed. If you find a pair of our frames that you love that aren’t one of the aforementioned brands, no worries, we can cut polarized lenses to go in most frames we offer.
What are UV-Protective Lenses?
What’s the primary purpose of UV-protective lenses?
UV-protective lenses are designed to block ultraviolet radiation from reaching your eyes. Unlike polarization, which affects visible light, UV protection shields your eyes from the invisible rays that can cause long-term damage to your vision and skin.
How do UV-protective lenses work?
These lenses either contain a special coating or are made from materials that absorb or reflect UV rays. Importantly, UV protection has nothing to do with how dark the lens is. Clear lenses can offer full UV protection if they’re made properly.
Benefits of UV-Protective Lenses
- Protects against UVA and UVB rays
- Reduces long-term risk of cataracts, macular degeneration, and other conditions
- Helps prevent premature aging of the skin around the eyes
- Essential for year-round protection, even on cloudy days
What should you look for?
Always check that your sunglasses offer “100% UV protection” or are labeled “UV 400”. This indicates full protection from rays up to 400 nanometers in wavelength, covering both UVA and UVB.
Designer brands at Adair that offer UV-protective lenses:
- Persol UV-protective lenses
- Maui Jim UV-protective lenses
- Rudy Project UV-protective lenses
- Randolph Engineering UV-protective lenses
- Costa UV-protective lenses
We carry a wide selection of both prescription and non-prescription UV-protective sunglasses in-store.
Do Polarized Lenses Automatically Offer UV Protection?
No, they don’t. This is one of the most common misconceptions we hear. Polarized lenses and UV protection serve different purposes. While many high-quality sunglasses offer both, some polarized lenses do not include UV protection. And some UV-protective lenses are not polarized.
If you want the full benefit, glare reduction and protection from harmful radiation, look for sunglasses that clearly state they offer 100% UV protection or UV 400, in addition to being polarized.
Which Is Better for You?
The answer depends on how you plan to use your sunglasses:
- If you spend a lot of time outdoors near water, snow, or roads, polarized lenses will improve comfort and visibility.
- If you’re mainly concerned about eye health and long-term protection, UV-protective lenses are essential.
- For the best experience, especially in Texas sun, choose lenses that offer both.
