Generally, the difference between polarized and non-polarized sunglasses lies in how they impact and protect your eyes when exposed to the sun. Polarized sunglasses are able to reduce the amount of glare and sun haze you will be exposed to while in a sunny environment, while non-polarized sunglasses will not.
Benefit to Polarized Lenses
A valuable benefit polarized lenses offer is almost complete protection against the horizontal glare from the sun, making the suns reflection almost unnoticeable, resulting in a clearer more defined vision. The intensity of the emission of the sun waves is much higher than the scattered ones. Therefore making this kind of light far more harmful for the eyes and especially for those who are driving.
Polarized lenses are used to block the intense light from sun waves reflected off of flat surfaces. The reasoning behind this is that polarized sunglasses are created with vertical polarization, while the light from the sun that is reflected off of flat surfaces is horizontally polarized. Also, various polarized lens colours are made and each of them offer different benefits under various circumstances.
Benefits to Polarized Glasses
- Reduce Glare
- Enhance Contrast
- Light Sensitivities
- Reduce Eyestrain
Benefits of Non-Polarized Sunglasses
Non-polarized lenses have a dark shade which in deed does reduce the intensity of light coming toward the eyes. However unlike polarized lenses, they are not able to counter and protect the wearer from horizontal polarization. Non-polarized lenses are unable to take into account that in which the direction the light is coming from, deeming them less protective than polarized lenses.
Even though polarized lenses improve visibility and are able to provide far better protection from the suns waves, there are some disadvantages. For example, polarized lenses may actually reduce visibility when looking at an image that is being produced by a liquid crystal display (LCD).
If you are one to be constantly under the sun partaking in activities such as jogging, outdoor sports, fishing or any outdoor activities, polarized sunglasses are most definitely the better choice for you when purchasing new sunglasses.
