The sun can be incredibly bright and damaging to the eyes which is why most of us take precautions by wearing a pair of UV-protected sunglasses. These lenses work to shield our eyes from harmful UV exposure, reducing the risk of causing damage such as cataracts, macular degeneration, temporary blindness, and photokeratitis. But, mostly, they help us see a little better on bright days by eliminating glare.
That is until the sun is too bright and the painful glare keeps us squinting. If sunglasses were made to protect the eyes, then how does this happen?
Polarized sunglasses may offer relief.
What are Polarized Sunglasses?
Polarized lenses are designed to prevent the glare from the sun or other light from reaching your eyes. To gain a better understanding of how they work, we need to get a deeper understanding of how the eyes see.
Your eye can see things because your eye is perceiving light rays that are reflecting off of an object. On its way to your eye, this light is often scattered thanks to different angles and surfaces between what you are looking at and your eye. However, in areas where there are flat surfaces and not enough angles to scatter the light, it reaches your eyes in a much brighter fashion. You typically see this happen when dealing with smooth or highly reflective surfaces – snow, metal surfaces (such as reflections off of cars), peaceful waters.
Regular UV-protected sunglasses don’t prevent the scatter of light, allowing it to still hit you right in the eyes. Polarized sunglasses, on the other hand, are coated with a special chemical that filters some of the light, making it a lot easier to see in bright conditions.
Benefits of Polarized Lenses
There are several benefits of polarized lenses that can make them a great alternative to UV-protected sunglasses. These include:
- Highly improved vision on the brightest days, offering clearer vision in bright light.
- Reduced glare and reflections from things like snow, metal, and water on a bright day.
- A greater amount of contrast with little distorted colors.
- Diminished eye strain due to bright lights.
Who Should Wear Polarized Sunglasses?
Anyone can benefit from polarized sunglasses, but those who spend a lot of time outdoors may benefit the most. The polarized coating darkens the lenses and it makes your outdoor vision much more clear and comfortable.
Keep in mind that these lenses may not be for everyone. For instance, they cannot be combined with reading glasses. Therefore, it is best if you speak to your eye doctor to discuss your lifestyle, your needs, and the best choice for your eye health.
