How Sunglasses Prevent Squinting

While our eyes are capable of absorbing light, any extreme brightness will need some type of protective wear.

Usually, we squint in order to reduce the amount of light that is entering our eyes. This can cause headaches and other pains. Not to mention early onset of wrinkles.

Sunglasses are crucial to prevent this from happening. A darkened lens helps to absorb the bright light, while the UV filter protects our eyes from the dangerous UV rays.
With that said, you should always check the label for the 100% UV protection logo before purchasing any sunglasses. Even the cheapest sunglasses have the logo, therefore you could afford these no matter what you budget is.

Obviously, your eyes matter more than fashion and the frame should fit close enough to your face.

Tests that have been conducted on manikins have shown that even lenses with the 100% UV logo have allowed sunlight to get around the side of the eyes due to the gaps in spaces.

It is recommended that large wrap around sunglasses be used for the best protection.

Depending on what you will be using the sunglasses for is the determining factor for how dark the lens should be. If you will be where there is a large amount of sunlight, such as in the snowy mountains if you are a winter sports enthusiast for example, then you will need very dark lenses.

For more average daily usage, you can use lighter lenses and still be protected. For frequent drivers, lenses with darker shading at the top and lighter at the bottom allow them to still see the dashboard while reducing the glare from the sun.

The lenses do not always have to be a dark black in order to protect you from the sun.

* Grey colored lenses are becoming very popular, and they reduce the most amount of color distortion.

* Brown and yellow lenses are also gaining recognition due to the fact that they reduce glare while helping block the sun. The only downside is that they tend to make everything have a weird shade of yellow which might counteract with your eyes after a while.

If you do purchase cheaper quality lenses, if they do not have the UV filters then you might as well not be wearing any sunglasses at all. They have to have the UV filter or else your eyes will be subjected to the hazardous UV light. While some consumers enjoy buying the designer frames, stay clear from the ones with very small lenses and thin arms.

They might look stylish while worn, but they are not protecting you at all from the effects of the sun on your eyes.
