What are the difference between polarized and non polarized sunglasses?

 Polarized vs. non-polarized sunglasses differ in their lens technology and how they handle light. Here are the key differences between the two:

  1. Light filtration: Polarized sunglasses have a special filter that blocks horizontally oriented light waves while allowing vertically oriented light waves to pass through. This helps to reduce glare from surfaces like water, snow, and roads. On the other hand, non-polarized sunglasses do not have this specific filter, so they only provide basic protection against bright light without the glare reduction benefits.

  2. Glare reduction: The main advantage of polarized sunglasses is their ability to significantly reduce glare, which is intense, reflected light that can cause discomfort and impair visibility. Non-polarized sunglasses can reduce overall brightness but do not have the same level of glare reduction.

  3. Outdoor activities: Polarized sunglasses are particularly useful for outdoor activities like boating, fishing, skiing, and driving, where glare from water, snow, or other reflective surfaces can be quite intense. They provide clearer vision and enhanced contrast in these situations. Non-polarized sunglasses are still suitable for general outdoor use, but they may not be as effective in reducing glare.

  4. LCD screens: One drawback of polarized sunglasses is that they can interfere with the visibility of certain LCD (liquid crystal display) screens, such as those on smartphones, GPS devices, and some car dashboards. When looking at these screens through polarized lenses, you may experience distortion or reduced visibility. Non-polarized sunglasses do not have this issue.

  5. UV protection: Both polarized and non-polarized sunglasses can offer UV protection, depending on the lens material and coating used. It is essential to choose sunglasses that block 100% of UVA and UVB rays to protect your eyes from harmful ultraviolet radiation.

In summary, salt water polarized sunglasses excel in reducing glare and providing enhanced visual clarity in specific outdoor situations. However, they may not be suitable for use with certain LCD screens. Non-polarized sunglasses are more versatile for general outdoor use but lack the glare reduction benefits of polarized lenses. Ultimately, the choice between polarized and non-polarized sunglasses depends on individual preferences and the intended use of the eyewear.

what's a good pair of sunglasses for cycling?

  Choosing a good pair of sunglasses for cycling is essential to protect your eyes from harmful UV rays, reduce glare, and enhance visibility while riding. Here are some features to look for when selecting cycling sunglasses: UV protection: Ensure the sunglasses offer 100% UV protection to shield your eyes from both UVA and UVB rays. This protection is crucial to safeguard your eyes from potential sun damage during long rides. Polarized lenses: Polarized lenses reduce glare from reflective surfaces, such as water, pavement, or car windshields. This feature enhances your vision and reduces eye strain, especially when cycling in bright conditions. Wraparound design: Look for sunglasses with a wraparound design or large lenses that provide ample coverage. This design helps to block sunlight and wind from entering around the sides, preventing eye fatigue and improving overall comfort. Lightweight and durable: Choose sunglasses that are lightweight and made from durable materials. This ...

why wear sunglasses when sport?

  Wearing sunglasses during sports activities offers a plethora of benefits that can significantly improve an athlete's performance and safeguard their vision. First and foremost, sunglasses equipped with proper UV protection shield the eyes from harmful ultraviolet rays emitted by the sun. Prolonged exposure to UV rays can lead to serious eye conditions, such as cataracts and macular degeneration, making it essential for athletes to invest in sunglasses that provide 100% UVA and UVB protection. Additionally, sunglasses with polarized lenses are particularly beneficial, as they effectively reduce glare caused by sunlight reflecting off water, snow, sand, or other surfaces. By minimizing glare, polarized sunglasses enhance visibility, allowing athletes to better track moving objects like balls or opponents, leading to improved reaction time and performance on the field. Moreover, certain lens colors, such as amber, brown, or copper, enhance contrast, making it easier for athletes to...
