How To Buy Sunglasses

Each activity has its perfect pair of sunglasses. It's essential to find the right pair so that you will be able to perform well. Wearing sunglasses will remove the handicap of getting blinded by the sun, and so you will be able to see your surroundings clearer, especially in high contrast situations, like summer or in snow. Here is a quick guide on how to get your perfect sunglasses:

Why do you need to buy sunglasses? Sunglasses will protect your eyes from the sun's harmful ultraviolet rays. They also improve your eyesight, especially when the sun is at its brightest.

In finding the perfect pair of sunglasses, you need to know what you will use them for. Each type of lens has its own purpose, and you need to buy one that corresponds to the activity you will be using the glasses for.

• If you are a skier, a hunter, or a pilot use Blue-Blockers. This type of lens has an amber-like color, and it blocks out the blue light. This improves visibility in situations where you will encounter very bright light and objects all around, such as snow and open skies.
• Polarized lenses filter out glare, which can cause blind spots. These are best for snow and water sports.
• Mirror-coated lenses greatly reduce the amount of light that enters your eyes, making you see more comfortably in very bright light. This is appropriate for situations in which you expect to be under the sun for long periods of time, such as the beach or the desert.
• Gradient lenses are gradually tinted from top to bottom, the top of the lens being the darkest. These lenses are often used for driving. Double lenses do not improve your sight in driving though, since double lenses tend to be dark in both the top and at the bottom but lighter at the middle.
• Photochromic lenses automatically adjust the darkness depending on the amount of ultraviolet light at any given moment.

Two general considerations are important, the color of your lenses and the material of the sunglasses.

• Color  Actually, there is no such thing as a perfect lens color; it always depends on your preference. The most popular lenses are gray and brown, since these are most effective in reducing the amount of light flowing in, and they also increase the contrast for more comfortable viewing.

  Yellow lenses are often used by skiers and shooters as well. This is because they help a lot when it comes to low-light surroundings and greatly reduce natural haze. It also improves the contrast of the image, making viewing sharper, which is excellent when tracking small objects and animals.

• Material  Polycarbonate lenses are very impact resistant, and also offer 100% ultraviolet protection. These are lighter and cheaper to produce than glass. Glass lenses are heavier and tend to be more expensive, but these tend to offer clearer vision than polycarbonate.

Once you find a perfect fit, go ahead and try them outdoors. If ever you experience dizziness, return the sunglasses and pick a different pair. Sometimes, it's possible that your eyes are not used to having certain color lenses, and you will experience a slight headache. Remove the sunglasses, close your eyes, and let them rest for a minute or two, then, open them up again.

Remember, your eyes are sensitive, and it makes sense to choose the eyewear appropriate to the occasion.
