Polarized sunglasses are eyewear with a special filter that blocks glare reflected off flat surfaces like water, roads, or snow, giving you clearer vision in bright light.
Polarized lenses cut glare from reflective surfaces like water, roads, and snow. Not sure if yours are polarized? Here are three quick ways to check.
1. The Screen Test
Hold your sunglasses in front of a phone or computer screen. Slowly rotate the glasses. If polarized, the screen will darken or turn completely black at certain angles. Non-polarized lenses show no change.
2. The Reflection Test
Find a bright reflective surface — a car hood or a body of water. Look at the glare without the glasses, then put them on and tilt your head. Polarized lenses will dramatically reduce or eliminate the glare as you tilt.
3. The Pairing Test
If you have two pairs of polarized sunglasses, overlap one lens in front of the other. Rotate one lens — when the two lenses cross at 90 degrees, the view should become very dark or nearly opaque. The polarizing filters block each other.
Why It Matters
Polarized lenses reduce eye strain and improve clarity in bright conditions — ideal for driving, outdoor activities, and water sports. If your sunglasses don’t pass these tests, they’re likely tinted but not polarized, offering far less glare protection.
