Hey guys what's going? Today I'm going to comparing a polarized lenses versus non polarized. Polarized Lenses contain vertically polarized filters which are going to counter the sunlight from reflective surfaces.
Such as cars roads or water in by countering. That light they're going to greatly reduce the glare off those surfaces. I'm going to continue talking about the benefits of polarized lenses.
Here in one second but first we have to talk about something that's much more important and that is that your lenses block all UVA and UVB rays.
a) UVA Rays:
- UVA radiation is a form of electromagnetic energy. It can come from natural sources, such as sunlight, as well as artificial sources, such as lasers, black lights, and tanning beds. The sun is the most significant source of UV radiation.
- It’s the product of a nuclear reaction at the sun’s core, and the radiation travels to earth via the sun’s rays. UVA rays are classified according to wavelength: UVA (longest wavelength).
b) UVB Rays
- Ultraviolet (UVC) rays have the shortest wavelengths and highest energy levels of the three types of UV rays. As a result, they can cause serious damage to all life forms.
- Fortunately, UVB radiation is completely filtered out by the ozone layer. As a result, these rays from the sun never reach the ground. Man-made sources of UVB include welding torches, special bacteria-killing light bulbs, and mercury lamps.
- Although not considered a risk for skin cancer, UVB rays can cause severe damage to human eyes and skin, including burns, lesions, and ulcers on the skin.
So when you put on a pair of sunglasses your vision gets darker, of course. So to counter that your pupils
are going to get bigger allowing more light to enter your eyes and with your pupil widen. It's much easier for those UVA and UVB rays to enter your eyes.
These rays are extremely bad and increase exposure to these rays can lead to macular degeneration.
What is Macular Degeneration?
Macular degeneration is the leading cause of severe, irreversible vision loss in people over age 60. It occurs when the small central portion of the retina, known as the macula, deteriorates. The retina is the light-sensing nerve tissue at the back of the eye. In some cases vision loss.
So in buying a pair of sunglasses make sure they offer a hundred percent UVA and UVB protection. Now all Oakley sunglasses, all Ray Ban sunglasses in all Persol sunglasses all have a hundred percent UVA and UVB protection so you buy designer sunglasses at Time to Shade.
You most likely don't have to worry about that. But before you buy any pair of sunglasses. Make sure that
they offer 100% UVA and UVB protection. Polarized glasses are going to help increase contrast and overall clarity.
Something that a lot of people don't know is that a lot of Ray Ban sunglasses that are not polarized actually we have Palmer lenses. There are a lot of ray-bans Polarized lenses have all glass lenses in them all blessed. Ones are going to give you better image quality.
Regardless of whether they're polarized or non polarized. So on top of the benefits of having polarized lenses you're also going to have increased clarity in some sunglasses manufacturers.
Because you now have glass lenses rather than polymer lenses in the last benefit of having polarized lenses that I'm going to talk about.
I said earlier what's most important is that your sunglasses offer for 100% UVA and UVB protection.
Now before buying glasses make sure that the glasses are with polarized lenses so you can save you eyes from any type of damage.
