These sunglasses also help enhance the normal light filtering capacity of our eyes. They are a form of protective eyewear designed primarily to prevent anything from causing discomfort to the eyes. Almost 99% of the “glare” that is created when the sunlight bounces off surfaces is blocked by the polaroids in your sunglasses.

Disadvantages of wearing sunglasses
Let’s begin by looking at some disadvantages of using sunglasses, because nothing can be all pros and no cons :
1. Fake goods in market
With the growing demand for sunglasses in today’s market, everybody wants something nice and cheap. But the problem with using cheap goods is that the manufacturing companies do Is that they use cheap polaroids and market it telling it will block all the UV rays but in reality it will only be balck or dark in color and does not provide any protection towards the sunrays. Now because these are black in colour, the pupils tend to dilate more and hence will end up getting more affected. These dark sunglasses that cause you to squint more must be avoided unless it’s been purchased from a trusted company. So, while they may fiter out the ambient light and the glare, the additional exposure towards the UV light increases the risk for cataracts, macular degeneration and even development of ocular melanoma which is a rare cancer. We have to keep in mind that polarization has nothing to do with UV light absorption, for the prevention of UV rays, these sunglasses come with an additional UV rays blocking filter or substance.

These chemical agents tend to prevent certain frequencies of light from entering the eyes, they also hinder some amount of lights emanating off LCD screens, although it may not be that evident from a direct line of view, at certain angles the visibility will also be completely zero. This is a problem for the people who have LCD screens at homes for tvs, or as their desktops at home or offices etc. this restriction is not limited to LCDs alone, heavy machine operators are also restricted from using the polarized glasses because of the way the filtration process works out as it hinders them from having proper vision.
