Key difference: The Polarized and Non Polarized Sunglasses differ in their designs and structures. The polarized sunglasses are designed with a special type of lenses which block the horizontal light coming from the sun, whereas this type of design is absent in the non-polarized sunglasses, hence they are not able to filter out the glare.

The sunglasses are developed in order to protect the eyes from the harmful sun’s radiations and extreme brightness. They have been in use in several sectors and fields for many years as they are applicable in some of the critical works and occupations. The polarized and non-polarized sunglasses have the tendency to protect the eyes from the high intensity UV Rays.

The polarized sunglasses were first developed for the fishermen, in order to catch and view the fishes from the lower levels. These are a special type of glasses which selectively block the glare. These are specifically developed to view those images which are away or not able to view from a finite distance due to the sun’s brightness. Polarized lenses are especially designed to protect the viewer’s eyes from horizontal glare created by the sun. The polarized sunglasses have been enjoyed for years, by experts, boaters and fishermen in order to reduce the unwanted glare from water. Also, these are now becoming more famous among sportsmen, including skiers, golfers, bikers and joggers, as well as the general public.

Non Polarized sunglasses, also function similar to that of the polarized sunglasses, but have some limitations. They protect the eyes from the harmful sun radiations and reduce the brightness, but along with that they also give a darker effect to the images. These sunglasses are designed and developed to filter out all the light due to which the image looks darker. They are available in uniform shades of dark colors which darken all light passing through them, regardless of the direction (polarization) of the light. These are generally preferred by everyone, as they are cheap in price. They have the ability to fulfill the basic function of protecting the eyes from the harmful bright intensity and light.

Now as the trends are changing, the polarized and non-polarized sunglasses are being used in daily lives. There exists a wide difference between the polarized and non-polarized sunglasses. The polarized sunglasses are more effective and preferred by the experts as they have the tendency to minimize the glare and provide a clear image; on the other hand this is not possible with the non-polarized sunglasses. The design and structure used for the polarized sunglasses are different than that of the non-polarized sunglasses. They use specialized types of quality substances which have the tendency to selectively block the light path, as compared to that of the non polarized sunglasses in which the light path is entirely blocked. The non-polarized lenses are quite cheaper as compared to the polarized ones, and often people choose the non-polarized sunglasses. Polarized sunglasses are much more expensive to manufacture than the regular non-polarized ones. That is why the polarized sunglasses are more expensive than regular ones.
