Making the case for polarizing lenses with Blue Revo coating

The Cádomotus Omega skate helmet has - besides all the specific characteristics you expect in protective head gear – an integrated visor. Omega is a helmet and goggles all in one. Nearly all skaters wear glasses to prevent eyes tears at high speeds, particularly those on skating on natural ice whose tears tend to freeze! If you wear glasses, you use them to see more detail. But these glasses, they give you something extra.

Specific Conditions

What's so special about a skate glasses? Dedicated to meeting the demands of conditions you’ll encounter during skating, when the speeds are high and everything is flying past you fast. In addition, and specifically if you’re skating indoors on ice, there is a lot of white light in rinks. Then there’s skating outdoors, skating on natural ice on a cloudy day. The ice gives off much glare and exposure flare, and that can really hamper your line of sight.

Polarized Lenses Filter Glare

Light has many interesting features, especially when it reflects over a horizontal field of vision, like a skating rink. Normally light is scattered in all directions, but when light is reflected from water, snow or ice, light moves along an axis. That’s what we call polarization. Ask any speed skater whose been exposed and they’ll tell you, this light is sharp, you can’t deny it. A vertical polarizing lens, such as the Aero Speed Skyfall lens, which is available with the Omega helmet, filters this light, thanks to the Blue Revo coating.

Blue Revo Coating

The Blue Revo coating is similar to the coating used for Ice Iridium Oakley’s and is used by Cádomotus in the Skyfall lens in the glass. Skyfall is one of three Aero Speed magnetic lenses Cádomotus makes for the helmets. Blue Revo is a special metal oxide coating which gives the lens specific properties, depending on the circumstances in which the lens has to perform. This coating is not only designed specifically to filter harsh glare, but also to give more contrast.

High Contrast

These glasses provide more contrast in conditions where with flat white light, such as in the indoor ice rinks, and also at high speeds. This is a distinctive for Blue Revo coating vs. uncoated glass. It prevents everything for you – glare and flare - and you will be surrounded by a white haze and helps you to focus. It is this focus that give your eyes rest and allows you to optimize your filed of vision when you’re skate to the limit.

The Skyfall Lens

This lens is perfect for skaters because the polarizing filters are reflecting light from the ice, so you won’t be blinded, and it increases the contrast in colors at high speed, allowing your eye to maintain crisp focus. It’s easy to see how these lens are “in for the win!”

Three Aero Speed Lenses Available

The Cádomotus Omega speed skating helmet is designed in combination with the Aero Speed lenses. Their precise fit follows the aerodynamic lines of the skate posture and form. The lenses magnetically attach to the helmet, fixed around your forehead. In addition to a clear view, it’s also a snap to change out or take off completely.

The available options:

  1. SkyNight. A neutral, clear lens
  2. Skyfall. A yellow lens with Blue Revo ® coating for increased contrast and glare reduction. Suitable for indoor ice rinks, in white light, and misty conditions.
  3. Skylight. A lens with a dark gray tint for lower contrast and eye protection in bright light.

Curved Lenses, The Risks and The Solutions

It’s never a good idea to buy “cheap sunglasses.” If you've ever worn a cheap pair of glasses, you may have noticed that things just don’t
seem right, or that you got after a while headache. Worse, bad glasses deceive your eyes. Objects don’t appear to be where they really are. And your eyes overcompensate and need to normalize again after you’ve used bad lenses. Sound familiar?

Glasses can deceive? A Quick History…

Around the 13th century, people began to make the first lenses. Literally polished stones, glass balls or even water. The idea was simple: the glass was centered and placed in a vertical position to the eye. Easy to calculate, easy to make.

In fact, many lenses follow this to idea to this very day. The lenses are relatively flat, with vertical curves centered in front of the eye. This isn’t a problem, until the application of different lens shapes, as in skating, where the glasses should follow the shape of the head, because we want to adhere to the laws of aerodynamics as much as possible.

In the 80’s, manufacturers were forming lens in many different shapes, and this round lens became popular, especially because athletes could appreciate its benefits – the wrap around. Sealed glass around the head was perceived as more aerodynamic, wind was channeled around the eye and vision improvements were realized, which is certainly crucial in any sport. But other problems occurred.

Round Glasses Bend Light

With the advent of the wrap-around style, lenses were now being made in a cylindrical manner to give full coverage to the face. And that’s where the problems started. Once lenses are more anatomical in form to your face, light rays start to bend.

Distortion of The Image

When light reaches your eyes in a distorted, bent way, you start to lose depth perception and sense of your surroundings based in reality.
This happens because the light is displaced from its normal line through the curved lens, changing your perception of where the objects
in your field of vision really are. (Think of the warning on your rearview mirror in your car.) With glasses on your head, this sense is amplified. You get the feeling that something is not quite right. This results in even eyestrain or headaches or worse – crashes! You can easily test whether you have prism lenses. Just look at an object with and without glasses and see if the image through the lens is deformed.

Sometimes this is ok, if you’ve ordered lenses consciously created with prism. But that’s rare, and it’s a technique used to help those with lazy eyes, for example. It’s not something you want in your lenses if you don’t need it.

The poor form of prism is what you find in cheap lenses. Uncompensated, curved lenses and distorted light paths ensure that your eyes have to work harder to focus and reflect reality, even in good weather. Your eyes are pretty good at working to correct situations like this and present your mind with a clear picture, but the result has been shown in research: eyestrain, headaches, it may even damage your eyes during prolonged use.

Light Waves Bend Back

For each problem, there is a solution. To resolve the prism effect, distorting the light waves, you have places in the lens come further forward than others. You direct the light. Here there are some complicated calculations needed to place the light in the right corner of your eyes. Directing light for vision is tricky because the rays of light come through your lens at a certain angle, and they must come out again at that same angle. It’s a three-dimensional problem, thus it’s pretty complicated to solve for.

But, in the world of science, anything is possible. The offset – pushing the lense further forward in some places - is called the point of 'decentralization'. A decentralized lens is a lens in which the optical center is no longer the mechanical center. The sides of the glass are thicker, so that the light waves, in spite of the curved glass, can again be forced into their own position. All of the prism effect that was caused by the circular glass is corrected by this technique, so your eyes do not have to do more themselves. This means that your eyes remain relaxed and sharp, they don’t get tired or strained. This is obviously extremely important during exercise and while skating.

The Omega skate helmet features Aero Speed lenses made according to these most modern techniques. The lens is completely formed around your head so it’s comfortable and gives you a great field of view. The lens is decentralized so that, despite the extreme curve, it provides maximum peripheral vision.
