I still remember the first time I put a pair of sunglasses on my son’s little 9 month face… despite my best intentions, it was off and on the sidewalk before I could even say “keep these on!”. Looking back, I think he hated that the lenses completely darkened his view of the world. Sometimes we forget that this change can be quite jarring for a chi...

Even prior to creating toucca kids, my wife experienced this first hand. Whenever borrowing my polarized sunglasses, she NEVER failed to commen...
Before we dive in and better understand how polarized lenses work and why you would want this feature for your little one’s sunglasses, let’s go back to the history books to see when the first sunglasses were invented and how they have evolved over time. Sunglasses are by no means a modern marvel; this contraption has been around through the centur...
The short answer is no. There are two general types of polarized lenses in the market today: 0.75 mm lenses and 1.1 mm lenses. While both types provide glare reduction, the different thickness of the polarizing film used can improve the durability of the lenses. The 0.75 mm lenses are made from thin sheets of film and are not as durable and impact-...
For those that have read this far, Bravo for getting through the history lesson! I’m sure some of you are thinking, “Great, toucca kids sunglasses are polarized! But how do I tell if sunglasses are polarized? How do I confirm this and how exactly does polarization work?” There is aneasy polarized sunglasses testthat you can perform, and fortunately...
Let’s start with some basics: According to the Merriam-Webster Dictionary: light: noun a: something that makes vision possible b: the sensation aroused by stimulation of the visual receptors c: electromagnetic radiationof any wavelength that travels in a vacuum with a speed of 299,792,458 meters (about 186,000 miles) per second; specifically: such ...
Ask students to explain how this “light” is polarized. Then ask students about the polarization of light and other electromagnetic waves. Then go through the four ways to polarize light: transmission, reflection, refraction and scattering. In this lesson, we focus on transmission and reflection.
Polarizing sunglasses cut road glare better in some positions than in others. When light reflects from water, asphalt, or other nonmetallic surfaces, it becomes polarized—that is, the reflected light is usually vibrating more in one direction than others.
