It is very important for a person to protect his eyes from exposure to the sun. A lot of light which comes from the sun may cause some harm to the human eye especially for those with sensitive eyes. It is therefore important that one gets to know all about sunglasses lens types so that he can get those that will be best for his eyes.
When you are able to understand the differences in the various lenses there are, you will be in a position to make a good decision when purchasing a pair for yourself. We all enjoy spending some time out in the sun but do not stop to think how this could affect us. With the great sensitivity of the eyes, extended periods exposed to the sun could have devastating effects. This is the reason why one should have all relevant information about these items which can be very helpful.
The different lenses in sunglasses normally give different levels of protection to the human eyes. The protection given by a regular lens is not as good as that given by a polarized one. They however help to some extent because they are uniformly tinted and thus cut down on the light that reaches the eye. As for the polarized ones, the tint is tiny and occurs as a ray of parallel lines. When the sun rays hit these surfaces, they bounce off as waves.
The polarized type of lenses cut down on the glare that occurs as a result of reflection by certain surfaces like water or objects such as metal objects with a shining effect. Translucent objects may also cause glare when they reflect light. The gadgets can hence be used by those who experience sight problems while in bright areas. The items make an object appear clearer and less shiny.
With the polarized devices however, you may find that LCD displays get distorted and you do not see things clearly. You may also notice a rainbow effect in case the windows of your car for instance are painted. The items are however good because they help a driver to see the road ahead clearly when driving under the scorching sun.
Apart from the polarized and regular lenses, there are also the super durable serilium lenses. These are mostly used by those who seek a thrilling experience or an adventure. They are made using a certain type of poly-carbonate which is manufactured in a way that it gives very good clarity.
The item is generally very light and very comfortable when put on. The poly-carbonate is widely used because it is very strong in nature and can withstand flying gravel. The sunglasses of this type therefore not only protect one from the bright light of the sun but from gravel as well.
When making a selection of the items, consider the number of layers there are. Layers do not work very well with lenses because they affect the vision. When the number of layers between the eyes and the object being viewed is increased, the chances of that image become distorted are higher. The optical accuracy is also reduced. One should find out all the necessary information he or she can concerning these items before acquiring them.
