What is the difference between the three sunglasses anti-UVA and UVB polarized light?

1. The damage to the skin is different: UVA has strong penetrating ability, but UVB is not easy to ignore because of its high energy and (UVB) damage to the skin is also great. Polarized light damages the skin weakly.

2. Different penetrating power: sunlight penetrates the earth's atmosphere, and a large part of UVB is blocked by the atmosphere, but UVA has a stronger penetrating power than UVB, so more than 90% of ultraviolet rays are UVA. And UVB does not even penetrate the glass easily. The penetrating power of polarized light is weak.

3. Different wavelengths: UVA and UVB are both ultraviolet rays in sunlight, and ultraviolet rays are invisible to the naked eye (if visible, it is called visible light). In a physical sense, ultraviolet and visible light are due to the different wavelengths of light. The comparison between UVB and UVA shows that UVA has a longer wavelength, while UVB has a shorter wavelength. The wavelength of polarized light does not.Basic  Plastic UVA And UVB Protective Sports Sunglasses is your good choice.
