When contemplating purchasing a couple of aviator sunglasses, most people don’t offer a thought about the lenses and simply consider how “cool” they are after they use them. While looks might seem to be important, light beer the lenses to supply adequate protection for your eyes is much more important.
A top quality couple of oversize aviator sunglasses begins with picking a the lenses. The lens material will need to have a uniform composition and become perfectly transparent. Additionally, the lenses must be ground and treated in such a way regarding provide maximum defense against harmful uv radiation.
Which are the Choices In Lens Material?
Generally speaking you can find three choices in lens material:
Plastic
Polycarbonate
Glass
Initially the only choice for lenses was glass, but because technology improved plastic and then polycarbonate became readily available for making sunglass lenses. With many choices in the marketplace available it could be confusing regarding which will be good for you.
Plastic Lenses
Plastic lenses are becoming popular due to the fact they’re light-weight and therefore more at ease to use. They eliminate the problem of glass lenses which sometimes slip down your nose and achieving to constantly push them back up.
One of many problems with plastic lenses, however, is they can easily be scratched. To solve this issue plastic lenses use a scratch resistant coating put on the lens and, if kept clean, will stay scratch free for a long time.
Polycarbonate Lenses
The main advantage of polycarbonate lenses is that they are thinner, lighter and shatterproof. Because these lenses are impact resistant you can drop a steel ball around the lens from quite a distance and the lens wouldn’t break or shatter.
Glasses with polycarbonate lenses are known as safety glasses since they perform a great job in protecting the eyes from injury. They are impact-resistant since the lenses are constructed with a really soft, pliable material; however, they are going to scratch effortlessly without proper care.
Glass Lenses
Glass lenses are heavier than either plastic or polycarbonate lenses and so are scratch resistant eliminating the necessity for a scratch resistant coating. However, drop a set of glasses with glass lenses and they very likely will shatter.
On the other hand, glass lenses supply the best visual acuity. Visual acuity will be the acuteness or clearness of vision, meaning everything you look out of glass lenses is going to be sharper than with some other lens material.
Liquid Crystal Displays (LCDs)
Today we are surrounded with devices like mobile phones, car dashboard displays and computer screens which use liquid crystal displays to present information to us.
Because LCDs utilize a polarizing filter having a vertical axis the data shown on these screens can be difficult or impossible to determine with polarized lenses. Polarized lens have been developed specifically to eliminate vertically polarized light waves, meaning trying to view an Vast screen with polarized glasses or sunglasses is a problem.
The solution, of course, would be to wear aviator sunglasses that aren’t polarized. In reality, really the only advantage for wearing polarized sunglasses happens when happen to be on the lake which in turn lets you see some depth into the water.
The Best Choice For Pilots
A pilot’s eyes are their most important asset, and pilots need to be capable of seeing everything as clearly as possible, like the LCD displays which offer flight and navigation information for them from your aircraft’s panel.
Which means that aviator sunglasses with non-polarized glass lenses are the very best selection for pilots. In fact, these would also be the best choice for anyone who drives a car by having an LCD instrument panel too.
