What is Polarization
Polarization is when light strikes a surface. All the
photons are vibrating in one direction instead of in random directions. The
light travels from ‘pole to pole’ along that plane. This is what causes the
glare off of shiny objects like Automobiles, chrome, and the shiny reflection
off of water. That’s what causes the mirror like effect on top of water that
prevents you from seeing through the waters surface. This glare distorts the
color of objects and makes them harder
to distinguish.
What does a polarized lens do
Polarized lenses work by filtering the waves of light by
absorbing some of the reflected glare while letting some of the other light waves to pass through them. One way to
think of how a polarized lens would work is to think of the Polarized lens as a
window blind. A window blind will block
light that strikes it from certain angles, while allowing light to pass through
from other angles. A polarizing lens will work when it is positioned at a 90
degree angle to the source of the glare. Polarized sunglasses are designed to
filter out horizontal light and the polarized lenses are mounted verticaly in
the frames and they must be carefully aligned so they will filter out the light
waves.
How are polarized sunglasses made
The first polarized lenses were a piece of polarizing film sandwiched
between two layers of flat glass. Because glass lenses are so heavy, thinner
and lighter plastic and polycarbonate lenses have become so popular.
Early polarized sunglasses had problems with delamination,
which is the separation of the polarizing film from the glass or plastic
lenses. The making of modern lenses have solved this problem, the polarizing
film is suspended inside the mold and the plastic is melted and poured in. The
plastic then hardens around the piece of suspended polarized film, creating a
solid material, rather than a layered one. Polycarbonate lenses are injection
molded, so they are made a little differently. The heat from the injection
molding would destroy the polarizing film, so the polarizing film is applied to
the front of the lens and covered with a scrach resistant coating.
Polycarbonate lenses are the lightest and thinnest polarized lenses available.
Who benefits from polarized sunglasses
Polarized lenses work well for for boaters, fishermen,
skiers, golfers, bikers, and joggers, who require a clearer view and
elimination of glare. These sunglasses when used for driving, can reduce the
glare that comes off the car or the surface of a road. Polarized sunglasses can
also be used indoors by light sensitive people. While ordinary tinted lenses
reduce brightness, only polarized lenses eliminate glare. While the first
polarized sunglasses were used mainly by sportsmen, the general public has
realized it’s many benefits, and now they have become so popular.

Prescription Motorcycle Goggles
It used to be at one time if you wore prescription glasses you had two choices, wear contacts so you could wear regular riding glasses or wear the goggles that fit over your prescription glasses. With todays technology, we now have many choices, you can purchase glasses or goggles that are RXable, meaning that they will except a prescription. Depending on the model, some frames can except the prescription or some models have a prescription insert. They usually do have RX limitations, be careful in picking out your model and knowing what your RX limitations are. Now with Prescription motorcycle goggles you do not have to look goofy by having only one choice. There are many choices to choose from. The ones that take the insert, the insert goes in behind your goggle lens, photochromic, or lenses that automatically darken from the UV rays will not work right behind these lenses. Even clear lenses that protect your eyes from harmful UV rays will not allow photochromic lenses to work. Clear lenses are best for in the insert and just use the smoked lenses that come with the goggles. Prescription motorcycle goggles that you can have your prescription put in the frame are nice because you can pick transitions lenses if thats what you like, or you can pick a sunglass lens to be put in. There are many prescription lenses to pick from. The insert you can have plastic lenses put in, that is the cheapest, because the insert goes in behind the goggle lens, if the goggle lens is a good polycarbonate lens, than you can go with plastic if you wish. Polycarbonate is lighter, about 30% thinner and shatter resistant. If your looking for thinner than polycarbonate you can also purchase High-Index lenses, They are not impact resistant but are thinner than plastic and lighter. They are pricier than plastic or polycarbonate. High Index comes in 1.60, 1.67, and 1.70. 1.70 is the most expensive, is 50% thinner than plastic and the lightest of them all. None of the High-Index lenses, Plastic, or glass lenses are impact resistant. Not a good choice for your Prescription motorcycle goggles unless your putting them in an insert and the insert is going behind a good impact resistant lens that has been tested like MIL-PRF 31013 or ANSI Z87.1 approved for safety.
Prescription Sunglass Lenses
Polarized Gray and Brown
If you drive a car or are exposed to sunlight, these lenses are a must for maximized protected vision. Polarized lenses greatly enhanced visual acuity, color contrast and comfort by blocking blinding glare. No other lens or treatment can perform this function. The most popular polarized colors are gray and brown. But, specialty polarized colors are available.
Drivewear
Combining two of the best technologies - Transitions Photochromic technology and Nupolar Polarization - these lenses are unique. The perfect solution for daytime driving conditions from overcast, low light conditions to daylight driving conditions to outdoor bright light. Drivewear lenses start with a high contrast green/yellow color that changes to copper then dark reddish brown and will activate inside your car. 100% UVA & UVB protection.
Transitions
The best choice for everyday use, these lenses protect your eyes from damaging UV rays and glare. Clear indoors and automatically darken with changing light, they provide convenient protection. These lenses are activated by UV rays and sunlight and do not darken inside a car. Available in gray or brown and we do recommend a anti reflective coating with these lenses.
There are many more different choices then this, so many more, can not mention them all here. These are the more common choices. You can buy prescription motorcycle goggles and the choices for lenses are endless.
