Polarized Sunglasses in the Beach

Polarized sunglasses are glasses that contain an invisible filter which makes the images more clear, reducing the intensity of the glare. The people mostly wear them for driving or fishing. It is useful to use the sunglasses when you go to the beach, exposing your eyes to the sun, particularly if you spend your vacations on the beaches of Punta Cana. 

In the Caribbean is practically summer all year round, which means that having a decent pair of sunglasses is relevant and much better if the sunglasses are polarized. 

Although the polarization has no effect on the absorption of the UV rays, many polarized glasses are now combined with substances that block ultraviolet light.  These glasses are very useful when driving a car or for practicing water sports, golf, etc.  These type of lenses are used in both the sunglasses and the eyeglasses. Its main advantage is that they reduce reflections, which is an optical effect.

How they work 

This type of sunglasses is also used to reduce the effect of reflective surfaces such as snow, or the surface of a lake. The reduction in the effect of these reflections is achieved through a process called polarization. The glare is eliminated because of the polarized filter. The light reflected by flat surfaces such as water or a road, generally reflects in a horizontal way. This horizontal reflection is blocked by the filter of the polarized sunglasses. The result is a reduction of the bothersome and sometimes even dangerous glare.

Interesting fact

Have you ever seen a 3D movie? When you go to the see a 3D movie  you get a pair of glasses so you can enjoy the film in three dimensions. Those sunglasses are polarized lenses. Part of the light reflected from the screen is polarized vertically while another is polarized horizontally, having the 3 dimensions effect.

Differences between regular glasses and polarized sunglasses 

One of the differences between the regular glasses and the polarized is that regular sunglasses do not block the glare. Because of this, the polarized glasses may not be used regularly in sunglasses with clear lenses, especially if they have been prescribed to correct a problem in your vision. This is because the glasses reduce the amount of light that enters the eye. Some drivers have commented that the polarized lenses cause distortions in the liquid crystal display (LCD) in which clocks and other instruments of the car cannot be properly identified. A similar problem occurs with some people that use polarized lenses in their sunglasses in snow. These users noticed the lost of the sensation of relief and contrast between the snow and the shadows.
The polarized lenses offer greater security by eliminating the glare produced by the reflection on the wet road, dashboard or other cars.  

And also help to protect sensitive eyes (especially if you plan to spend your day on the beach) or those who have had eye surgery or refractive cataracts. In addition to this, it helps by improving the perception of the colors . As I mentioned before, it eliminates the glare that limits the vision, because it has a polarizing integrated filter. Polarized glasses provide 100%  protection against ultraviolet rays and are highly recommended for athletes and for all types of outdoor activities. Remember to bring them with you when visiting Punta Cana. 

Where to get them

If you are interested in buying polarized sunglasses, you can visit your eye care professional, sunglasses store, online stores, etc. You can buy polarized sunglasses with or without prescription.

Is good to mention that polarized lenses have now become truly popular, as the benefits are greater and better than drawbacks. It is always helpful to get a second pair of sunglasses, so why not have a second pair that makes a difference in the comfort and clarity of vision.
