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 lenses reduce the amount of glare caused by surfaces that reflect such as water, shinning metal objects or semi-transparent gadgets. A person who experiences difficulty seeing in areas with bright light can make use of these devices. They make an object appear clear and not very bright as it really is.
These devices have their downside though. While looking at an LCD display, the images might appear distorted in a way and clarity is not very good. A sign that they do not offer the best clarity is when you experience a rainbow effect for instance if your car windows are tinted. They are still very useful though to drivers because they help the driver in getting a good view where he is headed.
Another type of lenses is the super durable serilium ones. They are widely common among those looking for adventure. The poly-carbonate that is used in their manufacture is special in some way and it gives a very good clarity.
It is also very light and the materials making it are strong. This type of poly-carbonate is the only one known to be strong enough such that it can stand the impact from flying gravel. This type of sunglasses does not only protect against sun rays but also can protect one from flying gravel.
It is important that one considers the number of layers that each pair of sunglasses has before purchasing a pair. A lot of layers are not advisable to go for because they affect the vision in some way. Lenses performance is reduced by increased layers. One should therefore buy those that have few layers.
