Fed up at not being able to read your instruments with Polarized sunglasses? You can with Zyon Sailing, This is the claim.

So on receiving the Zyon Sailing to test, this was my first interest. Sitting on front of my computer I first put on my own polarized glasses and turned my head until the screen went blank completely black. This represents the same result as a Chartplotters LCD screen.

Now using Zyon Sailing, I turned my head again and as I got to the same angle the screen started to go darker, but not very dark and you could still clearly see the screen and all the detail.

Next was time to trot off to a boat with a chartplotter, a Garmin 3210 color chartplotter with radar which we are in the process of looking at. Wearing the Zyon sunglasses below deck! at 45 degrees the screen got darker, but you did not get a totally blank screen as you would with regular polarized glasses.

You would not be wearing the glasses below deck but if this plotter was on deck in bright sunshine you would. In this case its annoying when you see a dark screen and you have to remove the glasses to see the detail.

When I tried them with my cell phone, the LCD screen was still clear and at the 45 degree angle the screen did go darker but you can clearly still read the digits, just like the plotter

First Test passed.

Its difficult to capture the test in a photograph, but the image below does capture the screen. Note the middle chartplotter image is a little darker than the left image. My impression was thats correct but in my opinion, its a little bit darker than this image, but still clear enough to read the all the details.

Rudy has taken the LCD obscuring polarization down a few notches to 96% just enough to keep the glare killing features but to allow sailors and boaters to read LCD displays and GPS plotters.

Photo Chromatic

The second test was the photo chromatic lenses.

The benefit of Photo chromatic glasses is that they change and compensate for the amount of brightness.

One issue I have, as do many boaters is when wearing glasses and then having to go below deck. Normally we forget to take them off and inside the darkness prevails, often resulting in banging your head or having to remove the glasses.

Going from below deck to on deck, I found that indeed the Photochromatic technology did compensate for the change in brightness. I did not need to take the sunglasses of when going below. This is a great benefit for boaters as we all know that the transition of relative darkness below and the harsh sunlight on deck can be hard on the eyes.

I have not had the chance to test the Zyon in bright sunshine on the water yet. The first day on the water was a bit overcast, but here the lenses let a lot of light through and you could see lots of detail. Even though lots of light came through my eyes felt relaxed. Again my cheap sunglasses were way too dark in these conditions, and the Zyon were far superior. In overcast conditions its amazing how much UV rays get through.

These Photochromatic lenses can benefit you, above deck and below deck.

Comfort & Construction

The fit and feel was good, the sunglasses did not pinch your head but still felt secure.

The hinge design uses a small pin that looks like it will stand some abuse as its fairy short. The side pieces have a joint that resembles a scarf joint and when opened up for use, the joint has no movement and behaves like a single piece.

Peripheral vision can be increased by removing the side shades.

The nose piece is a separate molding and is fixed with a stainless screw.

Peripheral vision can be enhanced by removing the side shields. I found the side shields to work well, but I can see that in some conditions you would remove them as the vision with them on was a little tunnel like. If I was on a starting line and needed extra vision I would remove them. Some sunglasses have thick side arms to block out side light and there you do not have an option.

One example of the Zyon Sailing use in the sailing at the professional level is Bribon the Spanish Royal TP52


The Zyon Sailing sunglasses are not cheap @ $250. However there are many advantages and the lens guarantee is worth looking at.

From the Rudy site

“Since the development of CR-39 and Polycarbonate over 40 years ago, there have been few advances and innovations in high impact-resistant optical polymer development.NXT® is a family of patented polyurethane optical polymers, transparent and unbreakable, originally developed for the military to provide superior protection and performance: NXT® was born in the USA in the early 1990’s when the U.S. Government contracted Simula Technologies to develop a new bullet-proof, transparent, and light-weight material capable of providing superior protection, reliability and longer lasting performance than polycarbonate. This material is also used in the windows in post Sept. 11 cockpit doors being installed on airplanes and Apache helicopter windshields panels; it is today available for Rudy Project Technically Cool Eyewear under a unique and unparalleled lens program: ImpactXâ„¢”.

Replacement Lens Guarantee “You Scratch Em, Rudy Project will Replace Em”. Rudy Project lenses are awesome, but when you are playing hard, stuff happens.

Lens Colors

The color of any lens plays a critical role in the management of light. Different lens shades and densities make it possible to enhance or preserve the perception of colors, contrast and visual acuity and can aid in glare reduction & elimination of UV rays. Every shade of lens and every treatment applied to them holds a specific function and purpose that allows you to manage your light conditions to meet the demands of your environment or activity.

Tints filter out enough of the right kind of light to reduce brightness without eliminating what you need to see. Reflective coatings reflect the color wavelength. For fly-fishing in the Caribbean Coast del Mars blue mirror is best. Yellow lenses increase visual acuity in low light conditions, best for road and trail Rose or violet makes details pop when light is flat especially against blue backgrounds best for water snow Gray green gray cuts glare preserves natural colors best for water and road Copper brown or amber universal tints that improve depth perception cut glare on sunny to partly cloudy days and minimize eye strain in haze best for road trail and water.

Specialty Lenses

For particular light conditions, Rudy Project offers technically advanced specialty lenses with high visual quality tailored to your needs. The various lenses enable you to perform and excel in any light or atmospheric condition you may encounter.

Case sunglasses protection

One issue I have with these glasses and any wrap around glasses is accidentally sitting on them. The case that is standard supply with Zyon sunglasses show below is pretty robust, and will serve to protect the sunglasses and has felt padding. The strap has two positions so you can make a loop to hang them from something, like your belt

Show below is the neck strap which has a floatation which can also save you getting neck burns from thin straps.
