Also, don't attempt to clean AR-coated lenses without wetting them first. Using a dry cloth on a dry lens can cause lens scratches. And because anti-reflective coating eliminates light reflections that can mask lens surface defects, fine scratches often are more visible on AR-coated lenses than on uncoated lenses.

In order to understand polarization, we must first understand light. Light is delivered in waves, and light waves that vibrate in more than one plane are referred to as unpolarized light. Polarized light waves, on the other hand, are light waves in which the vibrations occur in a single plane. This light travels in both vertical and horizontal directions. Horizontal light tends to be more problematic because it creates unwanted and potentially dangerous glare by bouncing off of different surfaces. In terms of polarized vs. non-polarized lenses, this is a key distinction. Polarized lenses transform these light waves (so they become polarized), and as a result less disturbing to your vision. Non-polarized lenses don’t filter light in this way, so the glare is much more noticeable.

AR coatings are especially beneficial when used on high-index lenses, which reflect more light than regular plastic lenses. Generally, the higher the index of refraction of the lens material, the more light that will be reflected from the surface of the lenses.

Circular polarization

Both benefits are due to AR coating's ability to eliminate reflections of light from the front and back surface of eyeglass lenses.

Typically, a production line includes multiple washing and rinsing baths, including ultrasonic cleaning to remove any traces of surface contaminants. This is followed by air drying and heating of the lenses in special ovens to further remove unwanted moisture and gases from the lens surface.

The visual benefits of lenses with anti-reflective coating include sharper vision with less glare when driving at night and greater comfort during prolonged computer use (compared with wearing eyeglass lenses without AR coating).

The first step in the AR coating process is to meticulously clean the lenses and inspect them for visible and microscopic surface defects. Even a tiny smudge, piece of lint or hairline scratch on a lens during the coating process can cause a defective AR coating.

The lenses are then loaded into special metal racks with spring-loaded openings so the lenses are held securely but with virtually all lens surfaces exposed for the coating application. The racks are then loaded into the coating chamber. The door of the chamber is sealed, and the air is pumped out of the chamber to create a vacuum.

Anti-reflective coatings (also called AR coating or anti-glare coating) improve both your vision through your lenses and the appearance of your eyeglasses.

Polarised and unpolarised lightvs unpolarizedlight

To see if a pair of sunglasses are polarized vs. non-polarized sunglasses, there is a quick little test you can do yourself. First, put on your sunglasses and take a look at your phone screen. If you see a rainbow in your line of vision obstructing your view of the screen, then the glasses are most likely polarized lenses vs non. This is a simple way to distinguish between polarized sunglasses versus regular. Most companies use traditional polarized lenses, but at Felix Gray, we use thinner polarization, which we specifically designed to work with modern devices. This way you can look at your screen with minimal distortion every time and still get the benefits of polarized sunglasses.

Most premium anti-reflective coatings include a "hydrophobic" surface layer that prevents water spots from forming and makes the lenses easier to clean. Some AR coatings also include an "oleophobic" surface layer that repels skin oils and makes it easier to remove smudges from the lenses.

The ability to eliminate glare is drastically different for polarized versus non-polarized sunglasses. That’s because polarized lenses are specifically engineered to reduce glare and ensure you can see clearly even in the direct sun. This glare created by the sun can be annoying and even dangerous in some situations. Therefore, polarized sunglasses work to eliminate this glare that interferes with your vision.

Additionally, another advantage of polarized vs. non-polarized is that polarized lenses have several benefits for your eyesight. These advantages include enhanced comfort, reduced eye strain, and even improved visual clarity. All of these factors are important to note when buying sunglasses polarized vs. non-polarized.

You’ll notice clearer vision while in direct sunlight when wearing polarized sunglasses vs. non-polarized sunglasses. By cutting out the glare, the polarized lenses will help you see better outside.

Applying anti-reflective coatings to eyeglass lenses is a highly technical process involving vacuum deposition technology.

Some eyeglass lenses have factory-applied AR coating on both lens surfaces. Other lenses, particularly progressive lenses and other multifocal lenses (i.e., bifocals and trifocals), have the coating applied after the lenses have been customized to your eyeglass prescription by an optical lab.

Additionally, the glasses feature thin polarized lenses made to work with digital screens so images are always accurate. Felix Gray sunnies also come with 360-degree protection that features a super hydrophobic backside AR (Anti-Reflective) coating to ensure that no damaging light can be reflected back into your eyes. All in all, polarized lenses vs. non-polarized have many benefits for your eyes and you can get great pairs at Felix Gray. They come in various colors and styles that both look great and are highly effective. If you have any questions or concerns before buying, during your search, or after you buy your new sunglasses, don’t hesitate to contact our Customer Experience Team through email, chat, phone, or Facebook messenger. If you’re looking for incredible quality, top-rated polarized sunglasses, Felix Gray is the place for you.

Today's modern anti-reflective coatings can virtually eliminate the reflection of light from eyeglass lenses, allowing 99.5 percent of available light to pass through the lenses and enter the eye for good vision.

Polarized vs. non-polarized sunglasses create an interesting debate on how they work and which is better suited for different situations. In terms of the polarized lens vs. non, both still typically protect against both types of UV light (UVA and UVB) in addition to bright light. However, there are two key differences between polarized and non-polarized sunglasses.

While the lens racks are rotating in the coating chamber, a power source within the machine focuses a beam of electrons onto a small crucible that contains a series of metal oxides in separate compartments. When bombarded by the beam of this electron "gun" in succession, the metal oxides are transformed into vapors that fill the coating chamber and adhere to the lenses in a specific order to form a precise multilayer AR coating.

For example, regular plastic lenses reflect roughly 8 percent of light hitting the lenses, so only 92 percent of available light enters the eye for vision. High index plastic lenses can reflect up to 50 percent more light than regular plastic lenses (approximately 12 percent of available light), so even less light is available to the eye for vision. This can be particularly troublesome in low-light conditions, such as when driving at night.

Each AR coating manufacturer has its own proprietary formula, but generally all anti-reflective coatings consist of multiple microscopic layers of metallic oxides of alternating high and low index of refraction. Depending on the AR coating formula, most lenses with anti-reflective coating have a very faint residual color, usually green or blue, that is characteristic of that particular brand of coating.

Polarized or not, sunglasses are a staple of everyday life. Polarized lenses versus non-polarized have many benefits that make them worth the purchase. Sunglasses of some kind (either polarized or non-polarized) should be worn during outdoor activities in order to protect your eyes from the bright sunlight. However, there are certain situations and conditions where it is important to know when to wear polarized sunglasses vs. regular.

By eliminating reflections, AR coatings also makes your eyeglass lenses look nearly invisible so people can see your eyes and facial expressions more clearly. Anti-reflective glasses also are more attractive, so you can look your best in all lighting conditions.

If you’re looking for the perfect pair of polarized sunnies, look no further than Felix Gray. Some brands charge more for polarized lenses, but that is not the case with Felix Gray. There is no need to worry if the sunglasses are polarized or not because all Felix Gray sunglasses come with polarized lenses to ensure glare reduction (anti-glare glasses). They also filter Blue Light to enhance color and block 100% of UVA and UVB light. The UV protection combined with the advanced Blue Light filter provides the best wearing experience possible. Blue Light scatters more than any other color (fun fact: that’s why the sky is blue!). This scattering can cause colors to appear muted and washed out. Felix Gray combats this with the proprietary color enhancement feature so you can see in true color.

Anti-reflective coatings are incredibly thin. The entire multilayer AR coating stack generally is only about 0.2 to 0.3 microns thick, or about 0.02 percent (two one-hundredths of 1 percent) of the thickness of a standard eyeglass lens.
