Glare is one of the most talked-about issues when it comes to external factors that affect proper visibility for the eyes. Polarized Sunglasses were specifically designed to tackle the glare that comes from the sun. When the sun hits horizontal surfaces such as water, land, or the hood of cars, it tends to cause a glare. his can be quite discomforting and at times even dangerous.

Wearing polarized sunglasses goes a long way in protecting the eyes from this frustrating glare caused by the sun hitting reflective surfaces. Since most of the reflective light that goes into the eyes is horizontal, the polarized lenses filter out virtually most of it. They allow only the light that comes in vertically to get into the eyes.

In essence, polarized sunglasses help you see better and reduce eye strain on bright and sunny days. People who love fishing or going to the beach will find them useful. But not only them, basically, everyone that spends time outdoors on sunny days.

BENEFITS OF POLARIZED SUNGLASSES.

Polarized lenses have various benefits such as;

  • Protection from blinding glare and reflection.
  • Protection from eyestrain.
  • Visual clarity and minimal colour distortion.
  • Protection from extreme light conditions, which can be harmful.

In addition to the above advantages, polarized sunglasses can be worn indoors by people with light-sensitivity, those that have just had cataract surgery, and those exposed to sunlight through windows.

DISADVANTAGES OF POLARIZED GLASSES AND WHEN NOT TO USE THEM.

Even though polarized glasses offer a range of benefits for people that spend most of their time under the sunlight, some people don’t feel comfortable wearing them. They claim these glasses make them feel dizzy, while others claim that the glasses create an artificial 3-D effect. Whether their claims being psychological or otherwise, people like this should opt for tinted lenses.

On the other hand, in some instances, polarized glasses are not advisable. These instances include anything with a liquid crystal display(LCD) as they can interfere with visibility. For example;

  • Automated Teller Machines(cash machines).
  • Cell Phones.
  • Wristwatches.
  • Car dashboard controls.

A point worth noting is that often at times, people confuse polarized lenses for photochromic lenses. Questions about which one is better also frequently pop up. However and although these glasses are similar, they are actually not the same and serve different purposes in different scenarios.

NOTE

Polarized lenses do not give you UV light protection. Just as you look to protect your eyes from glare and reflection, you should also look to protect your eyes from harmful UV light.
