Polarized Sunglasses – Why You Should Consider a Pair

By May 10, 2015 Sunglasses No Comments

Imagine being on a vacation in which you view a beautiful lake in the morning. What you will see will more or less resemble a flat mirror with little or no details and few colors. However, as soon as you slip into your pair of polarized sunglasses, you will find that the picture changes into a much more pleasant one. The glaring mirror of a lake has been transformed into a much more soothing and detailed natural spectacle. The colors are much more distinct and the contrast is sharper as well. These effects are due to the polarized lenses that your sunglasses have. Polarized lenses filter out the unwanted rays of the sun, reducing glare and allowing your eyes to see in a much clearer way.

Not only do polarized lenses omit the glaring effects of the sun, improving sight in the process, they also filter out the harmful UV rays, which can be damaging for the eye in intensely lit environments.

Since long ago, polarized sunglasses have been used by fishermen and seafarers to protect their eyes from the glare of the sea. This is especially important given the long durations spent on the waters. However, as time has moved on, the beneficial effects of polarized sunglasses were spotted in greater significance by sportsmen such as golfers, joggers, and athletes. Their popularity has grown ever since.

Moreover, these sunglasses can also be beneficial while driving, as they reduce the glare that can come off the windscreen of a fast-approaching car. This can be especially helpful on highways where visibility is key given the high-speed environment. Moreover, they are also used by people who have sensitive eyes right after a cataract surgery.

It is important to distinguish between polarized glasses and tinted glasses. Even though tinted glasses reduce brightness, they do not reduce glare, which is the hallmark of polarized glasses. Moreover, tinted sunglasses are more of a health hazard compared to not wearing sunglasses at all. This is because they cause the pupils to dilate, and since they do not block UV light, they let more of it in, damaging the eye in the process.
