Many patients assume dark lenses automatically protect their eyes.

Why UV Protection Matters in West Georgia
People living in Carrollton and throughout West Georgia spend a lot of time outdoors.
Whether you're:
mowing the lawn
golfing
fishing
hiking
coaching youth sports
driving for work
your eyes receive UV exposure every single day.
Because UV damage builds over time, protecting your eyes isn't just important during beach vacations.
It's important year-round.
This is one of the reasons we encourage every patient receiving an eye exam at West Georgia Eye Care to own a quality pair of UV-protective sunglasses.

Some do.
Some don't.
At West Georgia Eye Care, we offer complimentary UV testing for your current sunglasses.
Bring in any pair.

Whether you purchased them from an optical shop, department store, sporting goods retailer, or gas station, we're happy to check them.

Why Polarized Sunglasses Can Make Your Phone Screen Hard to See
Ever put on polarized sunglasses and suddenly your phone screen looks dim, weird, or even completely black? This is a common for local Carrollton polarized wearers and totally normal side effect of polarized lenses, and it comes down to simple physics.
Here's the easy explanation:
Your phone screen already sends out polarized light. Most phone screens (and many other LCD screens) are built this way on purpose. It's part of how the screen controls brightness and image quality.
Polarized sunglasses only let light through in one direction. They're designed to block glare, so they filter out light waves that don't line up a certain way.
When your phone's light and your sunglasses' filter don't line up, they can cancel each other out. Think of two window blinds stacked on top of each other. If the slats line up the same way, light passes through fine. If one set of slats is turned sideways compared to the other, barely any light gets through at all.
That's exactly what's happening between your phone screen and your sunglasses lens.
Frequently Asked Questions in Carrollton
Are polarized sunglasses automatically UV protected?
No. Polarization and UV protection are separate features. Always check for a UV400 or 100% UV protection label separately.
Where Can I Buy Quality UV-Protective Sunglasses in Carrollton?
If you're unsure which sunglasses provide real UV protection, our optical team at West Georgia Eye Care can help you compare lens options, explain polarization, and ensure your next pair protects your long-term eye health.
Do I need polarized lenses every day?
Not necessarily. Polarized lenses are most helpful when you're around glare-heavy surfaces like water, snow, or roads. For everyday wear, UV protection matters more than polarization.
Can dark sunglasses without UV protection hurt my eyes?
Yes. Dark lenses without a UV coating can cause your pupils to widen, letting in more UV rays than wearing no sunglasses at all.
Is UV400 the highest level of protection?
Yes. UV400 blocks essentially all UVA and UVB rays, which is the current standard for full UV protection.
Why does my phone screen look dark or weird through polarized sunglasses?
Your phone screen already emits polarized light, and your sunglasses filter light in one direction too. When the two don't line up, they can cancel each other out, making the screen look dim or black. Tilting your phone or your head usually fixes it, and it's not a sign that anything is broken.
