Polarized lenses have become quite popular in recent years. But, are they really worth it? Do they have more benefits? While normal sunglasses can be inexpensive, polarized glasses are expensive and you would want to know if investing in them is worth it. In this article let us talk about what polarized lenses are and what are the advantages of wearing them.

We receive many benefits from the sun. But, sunlight can pose serious vision problems. Sunlight reflecting off the water, snow or flat roads can create a glare that can disturb your vision and can often be dangerous. Sun glare can reduce the vision and cause accidents, snow blindness and can even sunburn your eyes. It is well known that long term exposure to sun glare is responsible for causing cataracts. Thankfully, due to the finding of polarized lenses, you can now shield your eyes against the dangers of intense glare.

In polarized lenses, invisible filters are built-in. These filters eliminate the amount of reflecting light that enters the eye. Polarized lenses not only reduce glare but also makes objects appear sharper and clearer. This provides great comfort when you are in the sun.

Polarized lenses are available for prescription as well as non-prescription. Therefore, you can still wear polarized lenses even if you wear glasses. Not only outdoors, but polarized lenses can also be worn indoors by light-sensitive people. A few examples of indoor use of polarized lenses are post-cataract surgery and those continually exposed to bright sunlight through windows.

Most polarized sunglasses provide UV protection as well. Protecting eyes from sunlight is important to maintaining healthy eyesight. Just as we put on sunscreen to protect our skin, it’s critical that we protect our eyes from UV rays too. It is great that today’s polarized lenses come with UV filters as you can receive many benefits by wearing them.

There are two types of polarized lenses: 0.75 mm and 1.1 mm. The 0.75 mm lenses work great for casual sports and everyday wear when resistance to breakage isn’t a big concern. The thicker lenses provide enhanced glare reduction and higher polarization, and it’s all worth the cost.

The quality of a polarized lens mainly depends on the quality of the lens material. Optical grade lenses are highest in quality and made out of mainly CR39 or mineral glass. Next, the quality of the polarized film and the way it adheres to the lens determines the efficiency of the filtration. High quality polarized lenses use a higher quality polarized film, sandwiched between the two lenses so that the film is perfectly aligned in the worn position. Once the lens and the films are made, an anti-reflective coating is applied to prevent reflections and glare.

Polarized lenses can make it comfortable to perform different tasks in the sun. Starting from walking, driving to complex tasks such as painting, sports, and even gardening can all be easy and safe if you have your vision clear and fine. Once you try these lenses, you will never regret the cost you bore.
