Do Polarized Lenses Block Blue Light? Regular tinted sunglass lenses reduce only the ambient light that reaches the eye or the transmittance of light. A modern type of polarized lens eliminates the glare, protects against the sun’s ultraviolet rays, and even blocks the blue light.

 SunRx filtered melanin lenses are a modern invention that comes in brown tints and blocks the blue light that some doctors believe can contribute to the progression of age-related macular degeneration that can lead to blindness. Such lenses would soon become more readily available in many polarized sunglasses.

What is Blue Light?

Blue light is found in the ultraviolet spectrum of sunlight and is the actual form of ultraviolet light. It has a high radiation effect which is harmful to our eyes.

The sun is where we usually get most of our blue light, but other things can cause this ultraviolet light to harm our eyes, such as a flash from a welder torch, xenon arc lamps, high-intensity mercury vapor lamps, video display terminals, and even something as innocent as fluorescent lighting.

How Blue Light is harmful for our eyes?

The rapid growth of age-related macular degeneration is a long-term risk to blue light.

In addition to very severe issues with the eye ‘s wellbeing, even anything as basic as the sleep cycle is disrupted by blue light – just to illustrate the seriousness of that. This is because the melatonin we produce naturally regulates our nervous system. The blue light actually affects the melatonin production process of our nervous system.

What about Lens Polarized?

There are normal lenses, and then there are polarized lenses. The gap is very growing. Polarised lenses are particularly designed to block harmful blue light for this purpose. Even those tinted lenses do not keep ultraviolet light out.

On the other hand, polarised lenses work because of their fabrication and design. Its special design is unique and innovative, but it works best to protect you from the sun or any other factor leading to ultraviolet blue light.

How do polarized lenses work?

In every direction, sunlight is dispersed. But the light reflected by the surfaces appears to polarize as it reaches flat surfaces — meaning reflected light beams pass in a uniform (typically horizontal) direction. This creates an irritating and sometimes dangerous light intensity, which causes light and reduces visibility.
Polarized lenses have a special filter, which blocks intensive reflected light from this kind and reduces glare and discomfort.
Although polarized lenses enhance comfort and visibility, you can encounter instances where such lenses are not recommended. One example is downhill skiing, where you want to see the bright mirrored light patches because the light alerts you of icy conditions.
Polarized lenses also reduce the visibility of Liquid Crystal Display (LCD) images found on some digital screens such as ATMs and gas station pumps.
You may also find it harder to view the screen on your phone with polarized lenses (depending on the type of screen technology you use).
Boaters and pilots can also encounter similar problems when viewing LCDs from instrument panels, which may be a key issue when making split-second decisions based exclusively on on-screen details.

Despite these exceptions, the polarized sunglasses offer great advantages in reducing eye strain and sunlight discomfort.

Conclusion

The first step in obtaining the best possible view with polarized sunglasses is to schedule an eye test.

NEED AN EYE EXAM? Find your eye doctor and arrange an appointment.

If you have even a little bit refractive error you can see your exterior vision so clearly and comfortably with the bright sunlight using the prescription polarizing lenses.
