|Recommendations on dark tinted goggles?||js5280|

|Wondering if people have recommendations on dark tinted goggles. I plan to do a tri whose open water course is directly into the sun and it is extremely hard to make out the buoys because of it. I do have tinted goggles but there weren't near dark enough for this swim. I notice there is a Seal Mask with tint, mirrored, and photochromic lenses. Would one of these work better? Any other brands people would recommend?|

|My swimmers train out of an outdoor pool, and have had a fair ammount of luck with the speedo ultra vision.
My personal fav, from my racing days were the "swedish" goggles (go to a swim store, they should know what you mean, you assemble them yourself and they have a little blue nose piece) which come in a gold or silver tint which are very dark and baring that they fit your face work the best of any I have tried.
|Thanks, will have to check on those options. (nm)||js5280|

|Be careful using them in an open water swim. I have used them for about 15 years and while I am used to them, they are not the most comfortable goggles out there. The catch to them is that they have no silicone or rubber seal. The eye pieces sit almost completely in your eye sockets. They are great in a pool in competition because of the low profile. If you get kicked in the face, you are going to get a black eye and perhaps even a nice cut that turns into a cool scar - trust me on that one...
I would recomend looking at the Aquaseal mask or the Aquaseal Kaiman goggles. They both come in some serious tints and are super comfortable and give you a better field of view. I still wear my swedes on occasion, but the Kaimans are the best goggles I have ever worn.

|Found this info on different lens coatings. I think I'm going to try a polarized lens and see how that works. It looks like mirrored is a good option too as it appears blocks out more light.
Usually associated with ski and swim goggles, anti-fog lenses have a special clear coating which dissipates the water droplets that form the "fog" on the inside of your lenses during strenous activity. Some goggles will also have a venting system (usually in the form of small openings along the side) to aid the no-fog process. Many of our ski goggles are no-fog (Killer Loop, Bugz and Bolle are prime examples), while all of Barracuda's swim goggles are anti-fog, and Coyote makes a few active wear sunglasses with a no-fog coating.
Polarized lenses have the benefit of filtering out reflected light and glare off water, pavement and snow. This lens works great for fishing, boating, driving or any other glare intensive activity. Polarized lenses are the best way to eliminate both glare and UV light. The principle of a polarized lens can best be described by observing the use of a venetian blind. The blind blocks light at certain angles, while allowing light to transmit through select angles. Polarization is achieved by shutting out 100% of undesirable light and allowing 100% of desired light through the lenses. Many polarized lenses feature AR coating on the back of the lens for even better clarity and reduced back glare (Anti Reflective (AR) Coating is an extremely thin layer of film that is deposited on either the front or the back surface of the sunglass lens that virtually eliminates reflections from the back of the lens). Be sure to check out the nice polarized lines from Maui Jim, Native, Costa Del Mar and Ocean Waves
Photochromic lenses have an adjustable tint that changes with the amount of available light. In bright sunlight they darken; when light conditions are not as bright, they lighten in color. Note that the photochemical response does not happen instantaneously. It normally takes (on average) one to two minutes for photochromatic lenses to adjust from very low levels of light to very bright and vice versa. Also, the tint change is usually not very dramatic. Photochromatic lenses usually range from 10% light transmission in bright light to 20% light transmission in low light. A difference of 10% transmission is not always noticeable, but over long periods of time, you should notice a significant reduction in eye strain. As a general rule, photochromatic lenses are almost always glass lenses due to the nature of the photochemical application process. Hobie and Action Optics both make a photochromic-polarized lens, while Serengeti makes all of their Drivers lenses photochromic.
Mirror-Coating and Mirrored Lenses-
Mirror coating is like the name indicates, is a mirror coating applied to the front surface of the lens. A special treatment is applied to the front surface of each lens through a vacuum process that allows the lens to take on the properties of a two-way mirror. Mirror coatings can reflect the light rays that are emitted from surfaces such as water, snow and ice therefore making the lens darker than an average un-mirrored lens. Many Mirror coated lenses may also feature AR coating on the back of the lens for improved vision and reduced back glare. Mirror coating can be applied to almost any kind of lens material.

You may have already heard about the horrible effects of overexposure to ultraviolet radiation: Melanoma and skin cancer, increased risk of cataracts, etc. Thankfully, ultraviolet radiation is a high-energy, lower-wavelength radiation (higher than that of visible light, hence the "ultra-" in ultraviolet) and as a result, it is easily reflected.
