When considering purchasing a set of aviator sunglasses, a lot of people don’t provide a thought about the lenses and just consider how “cool” they are after they hook them up to. While looks may seem to become important, the ability of the lenses to supply adequate protection for the eyes is far more important.
A top quality couple of oversize aviator sunglasses starts off with the selection of the lenses. The lens material will need to have a uniform composition and stay perfectly transparent. In addition, the lenses should be ground and treated in such a way as to provide maximum defense against harmful uv radiation.
What Are The Choices In Lens Material?
Most of the time there are three choices in lens material:
Plastic
Polycarbonate
Glass
At first the only option for lenses was glass, but because technology improved plastic and then polycarbonate became available for making sunglass lenses. With many choices in the marketplace available it could be confusing as to which would be best for you.
Plastic Lenses
Plastic lenses are becoming popular for the reason that they’re light-weight and for that reason more comfortable to use. They get rid of the problem of glass lenses which sometimes slip down onto your nose and having to constantly push them back up.
One of many difficulties with plastic lenses, however, is they could be scratched. To resolve this challenge plastic lenses have a scratch resistant coating placed on the lens and, if kept clean, will continue to be scratch free for some time.
Polycarbonate Lenses
The benefit of polycarbonate lenses is they are thinner, lighter and shatterproof. Because they lenses are impact resistant you might drop a steel ball around the lens from quite a distance and the lens wouldn’t normally break or shatter.
Glasses with polycarbonate lenses are known as safety glasses because they do a great job in protecting your eyes from injury. They may be impact resistant since the lenses are made of an extremely soft, pliable material; however, they will scratch effortlessly without proper care.
Glass Lenses
Glass lenses are heavier than either plastic or polycarbonate lenses and therefore are scratch resistant eliminating the necessity for a scratch resistant coating. However, drop a pair of glasses with glass lenses and so they very likely will shatter.
On the other hand, glass lenses provide the very best visual acuity. Visual acuity may be the acuteness or clearness of vision, meaning whatever you see through glass lenses will be sharper than with any other lens material.
Lcd tv Displays (LCDs)
Today we have been surrounded with devices like smartphones, car dashboard displays and computer screens which use liquid crystal displays to provide information to us.
Because LCDs make use of a polarizing filter having a vertical axis the data shown on these screens can be tough or impossible to determine with polarized lenses. Polarized lens were created to remove vertically polarized light waves, meaning attempting to view an Vast screen with polarized glasses or sunglasses is an issue.
The perfect solution is, needless to say, is always to wear aviator sunglasses that aren’t polarized. In reality, the only real advantage for wearing polarized sunglasses occurs when you are on the lake which allows you to see some depth to the water.
The best option For Pilots
A pilot’s eyes are their most critical asset, and pilots need to be able to see everything as clearly as you can, like the LCD displays which offer flight and navigation information in their mind in the 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 your best option for everyone who drives an automobile with an LCD instrument panel too.
Recommended Manufacturers
Today the 3 leading manufacturers of non-polarized glass lens aviator sunglasses are:
