The purpose of polarized sunglasses
Polarized sunglasses are specific eyewear intended to decrease glare from surfaces like water, snow, and glass. Polarized sunglasses can be used for specific games and driving to help participants see more clearly and keep away from potential risks.
What are polarized lenses?
Polarized lenses are an extraordinary choice for anyone who spends time outdoors. In case you're working outside, particularly while doing high-glare exercises around water or snow, polarized lenses help diminish glare and give extra clearness while protecting your eyes.
There are a variety of choices for eye protection, and polarized lenses are just one probability. Just like staying in the sun for hours to protect your skin, your eyes also need protection.
Benefits of polarized sunglasses

3. help to minimize glare
4. Reduce eye fatigue
5. enhance visual comfort
6. reduce harsh reflections
Disadvantages of polarized sunglasses
Although polarized sunglasses are very suitable for protecting your eyes from strong light and reducing glare, there are some disadvantages.
Disadvantages of polarized lenses
1. watch the LCD screen
3. Low light conditions and night driving
Whether it is psychological or neurological, some people insist that lenses make them feel dizzy or perplexed, while others persist in that they create artificial 3-D effects.
For these people, the way the photoreceptor cells at the back of the eye receive vertical light signals may be different from the rest of us. 4 In this case, tinted lenses may be the best choice.
Some occupations need workers to be able to read certain numbers on the LCD. Avoid using polarized lenses for special workers as the numbers on the LCD often interfered with by polarized sunglasses.
How polarized lenses work?
Polarized lenses have a wide selection of colors, contingent upon the material of which the lenses are made. Darker colors give more significant levels of polarization.
Polarized lenses have an uncommon compound applied to filter light. The molecules of the chemical are arranged in a row to prevent some light from passing through the lens. Consider it as a mini shutter hung in front of the window. Only the light passing through the shutter openings can be seen.
On polarized sunglasses, filters create vertical openings for light. This means that only light that enters your eyes perpendicularly can pass through these openings. For example, the lens will block all horizontal light waves reflected from a gleaming lake or shiny car hood. Therefore, the image you see with polarized lenses is darker than usual, but the object looks clearer and it is easier to see the details.
The most common colors for polarized lenses are brown and gray. However, depending on the eyewear manufacturer, there may be many other colors to choose from. Blue, yellow or other colorful colors are also very popular.
How to identify the polarized lenses?
1. Try to observe the reflective surface with and without lenses.
2. The other method is to check polarized lenses through look at the LCD screen.
Polarized lenses are a good choice for people who often spend outdoors. Not only can they reduce brilliant reflections and unnecessary glare, but polarized lenses are also conducive to help advance visual clarity in bright environments.
Bear in mind polarized sunglasses cannot protect you from looking directly at the sun. Even if the outside is not particularly bright, you should always take protective measures to protect your eyes from harmful UV rays.
When buying sunglasses, don’t just think about appearance. Polarized sunglasses are one of the few sunglasses options you must keep your eyes healthy in the sun.
