Since spring has arrived, it’s the perfect time to consider updating your eyes’ sun protection. Outdoor activities and enjoying the sunlight are on everyone’s agenda as warmer weather invites us back outside. Consider choosing a pair of polarized lenses to protect your vision and reduce those annoying instances of bright glare.
Polarized vs. Unpolarized Light
Unpolarized light is everywhere around us, coming from sources like the sun, light bulbs, and even flames. These light sources emit vibrations or waves that move in all directions. When the direction of these vibrating light waves is altered—such as when they hit a smooth surface and reflect—the light becomes partially polarized. This is also known as glare, which occurs when too many waves of light become partially polarized and oriented horizontally toward our eyes.
Excessive exposure to partially polarized light can be harmful to your vision. Overexposure to bright light and glare can cause squinting, eye fatigue, and even temporary loss of vision in severe cases. You’ll know your eyes are being affected when you’re outdoors in a bright environment and find yourself shielding your eyes from flashes of glaring light.
