When contemplating the purchase of a pair of aviator sunglasses, a lot of people don’t give a thought about the lenses and merely consider how “cool” they look once they use them. While looks may seem to become important, ale the lenses to supply adequate protection for your eyes is far more important.
A top quality pair of oversize aviator sunglasses starts with selecting the lenses. The lens material will need to have a uniform composition and be perfectly transparent. Additionally, the lenses has to be ground and treated in a way concerning provide maximum defense against harmful uv radiation.
Do you know the Choices In Lens Material?
In most cases you will find three choices in lens material:
Plastic
Polycarbonate
Glass
In the beginning the only choice for lenses was glass, but because technology improved plastic then polycarbonate became designed for making sunglass lenses. With several choices on the market available it may be confusing regarding which would be best for you.
Plastic Lenses
Plastic lenses are becoming popular for the reason that they’re light-weight and thus more at ease to wear. They get rid of the problem of glass lenses which sometimes slip down onto your nose and having to constantly push it well up.
One of many issues with plastic lenses, however, is that they can easily be scratched. To resolve this problem plastic lenses have a scratch resistant coating put on the lens and, if kept clean, will remain scratch free for a long period.
Polycarbonate Lenses
The 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 a considerable ways as well as the lens would not break or shatter.
Glasses with polycarbonate lenses are called safety glasses simply because they perform a good job in protecting your eyes from injury. They may be impact-resistant as the lenses are constructed with a really soft, pliable material; however, they’ll scratch quickly without the right 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 most likely will shatter.
On the other hand, glass lenses provide the absolute best visual acuity. Visual acuity is the acuteness or clearness of vision, which suggests whatever you see through glass lenses will probably be sharper as compared to every other lens material.
Live view screen Displays (LCDs)
Today we’re 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 with a vertical axis the information shown on these screens can be tough or impossible to find out with polarized lenses. Polarized lens were created to remove vertically polarized light waves, meaning trying to view an LCD screen with polarized glasses or sunglasses is a concern.
The solution, obviously, would be to wear aviator sunglasses that aren’t polarized. In fact, the only real advantage for wearing polarized sunglasses happens when happen to be on the water which in turn allows you to see some depth in to the water.
Your best option For Pilots
A pilot’s eyes are their most important asset, and pilots have to be able to see everything as clearly as you possibly can, like the LCD displays which give flight and navigation information in their mind from the aircraft’s panel.
Which means aviator sunglasses with non-polarized glass lenses will be the best choice for pilots. In reality, these would be also your best option for anybody who drives a vehicle by having an LCD instrument panel also.
