Negative and positive effects of polarized sunglasses

One of the most used types of sunglasses are those with polarized lenses. Polarized sunglasses have numerous beneficial effects for the people wearing them. None other type of sunglasses is capable of blocking glare like polarized sunglasses are. And as we all know sunglasses are more than just a trendy accessory, so they need to have good qualities for protecting our eyes and vision as well. This is exactly why polarized sunglasses are one of the most preferable types of sunglasses. However there are some negative aspects of sunglasses with polarized lenses which you should know about. When you know the negative and positive effects of polarized sunglasses you will be aware when they will be useful for you and when not. First of all sunglasses (in Denmark we call those solbriller) with polarized lenses are mainly designed to block reflected sunlight also known as glare. This type of light is horizontal and this is why the other types of sunglasses are not capable of blocking it properly. Only the sunglasses with polarization have special filters in their lenses that allow them to perfectly block the reflected sunlight or glare. The major positive effects of polarized sunglasses are that they allow the person wearing them to see clearly and without any frustration whatsoever even in the brightest days. When the sun is very bright the amount of glare is significantly higher, this is why your eyes are getting frustrated and tired when you spend a lot of time in the open in the bright and sunny days. Polarized lenses will improve your vision in these situations and your vision will be safe. Glare can cause some vision disorders and eye related problems, a major benefit of polarized sunglasses is that they will effectively protect you against all of those problems. Since almost every surface reflects sunlight, every time you are outside your eyes are exposed to glare, so without polarized sunglasses you are exposed to all of the dangerous effects it brings as well. This is why sunglasses with polarized lenses are your best choice whenever you are going to spend a lot of time in the open, whether it is for taking a walk, playing some kind of a sport, or even driving your car, polarized sunglasses will be an effective way to protect your eyes. Despite their numerous advantages, polarized sunglasses can be a bit of a problem sometimes. Though they are usually very useful for drivers, if the windows of a car are coated with polarization filters themselves, wearing polarized sunglasses is not advisable. In this situation the both polarized surfaces might worsen your vision and there might be an illusion that there are dark spots on the windshield of the car. Viewing liquid crystal displays or LCDs is also a bit of a problem with polarized sunglasses. Their filters will make those displays very unclear and it will be hard to read them with your sunglasses on.

Camera Lens and How to Take Care of Them

The camera lens is one of the most important parts of a camera, the image quality will ultimately depend on the lens quality. There is no such thing as the perfect camera lens because each lens has its advantages and disadvantages. Standard lens has those with a length of 50mm, the most used format. All SLR cameras come with interchangeable lens, perfect to replace this lens for the other for that particular photo.

When shopping for more lenses for your camera keep an eye on some technical definitions. The aperture is the maximum amount of light that the lens allow to pass through the sensor and the smaller this number is, the more light will pass through the sensor the better the image will be. The perfect number is one but that is not possible yet. The best around is 1.2 but that’s not necessary for the average user, above 2 and even three is good enough for a good picture.

The next feature to consider is the focal length, if you use a telephoto lens you will be prone to take blurred images because focusing on distant objects increases the movement sensitivity. The wide angle is perfect to photograph nature because you can capture more field than with the telephoto lens, each lens has its own advantage and no lens is perfect for all situations.

There is another characteristic you must pay attention to which is the zoom. A lens with no zoom is not able to approximate distant objects to you so a zoom lens is the ideal pick here. A zoom of 3x is more than enough for the home user. Fixed lens come with the advantage of possessing more image brightness than zoom lens.

Camera lens will be as good as the protection you give to them and an SLR camera lens is such an investment. It will be scratched without proper care and once scratched there is no way to fix it, you will need to buy a new one to have high quality pictures again. You can fully protect it by buying a camera hood for each lens you have. They are so cheap it makes no sense not to have one for each and does wonders to help protect the lens. This will protect the lens if the camera falls down absorbing some shock and to take damage in case something sharp collides with the lenses. Another way is to purchase a filter, the best protection move you can make for your camera lens.

The filter is placed between the lens and the rest of the world so you guessed it, the filter will protect the lens from UV rays, from scratches and pretty much anything else. Finally use the camera lens cap, some people have it but do not use it, which is so wrong. The cap will ensure that nothing will be able to damage the lens, except a big fall.

Killdeer birds are cute rather plump birds with rather long legs for their little bodies. They like to run in the open ground rather then fly over it. Seem they feel that they will miss some tasty morsel. They have a shrill kill-deer call that sometimes hurts the human ear. It most assuredly hurts other birds and wild life in the area. Killdeer are strange birds, they like or rather prefer open grassy and rocky areas that are not always by waterways.

With your binoculars take some time and look for general markings and characteristics, things that you notice right off. Do not spend a lot of time trying to memorize different aspects of the Killdeers. Just look for general information and then you will be able to quickly recognize what group these birds belong to by noticing size, general shape, colors and their behavior.

I suggest that you keep a note book of these characteristics. You can add to it from time to time. This will help you understand and learn. But be patient and note things only one at a time. Otherwise you may get tired and discouraged because you cant remember everything at once. It will all come in time as you watch these birds. Also take a look at the field marks such as a wingbar and eyering markings to tie some IDs down.

Please remember also to note what time of year you see them as well as other kinds of birds you see in your neighborhood. Then you will be able to keep track of them better next year when the return.

A good field book on birds will help, but do not try to memorize everything in it all at once. Just learn about your specific bird of interest.

Color Pattern
Golden brown color above with two dark bands across the white breast
Likes to run swiftly along the ground or will break into stiff-winged flight, has a shrill kill-deer call
