6 Aspects Need to Consider When Newbie Buying Ski Goggles

At present, there are many well-known ski goggles on the market. For Newbie, it is really confusing. What priorities should be chosen in the end?

No.1 Anti-fog Effect of Lenses

Anti-fog Effect of Lenses

Objective selection should be made according to the actual use environment. Different brands of snow mirrors behave differently in different environments, and the products of different models of the same brand have different anti-fog and anti-fog effects. At the same time, the anti-fog effect will be different under the premise that the face material, position, design and wearing method are different.

However, in a comprehensive comparison, under normal snow conditions, the anti-fog effect is directly proportional to the price. However, in cold weather, if the face is not well equipped, no matter what brand, the anti-fog effect will be greatly reduced.

At present, some international big-name snow mirrors use double-layer lenses, which can also effectively prevent fogging caused by heat conduction inside and outside the lens; and the well-ventilated frame allows the internal air to circulate and perform automatic adjustment of the air inside the frame, which can effectively maintain heat And dehumidify to help prevent fog.

No.2 Discoloration Technology

Discoloration Lenses

At present, discoloration technology has almost become the weather vane of all-weather lenses. But objectively speaking, all the principles of color change have their degradation process, which means that it is impossible to change the color as coolly as they did when they bought it for a lifetime.

Discoloration performance will have a longer or shorter life depending on the frequency of use, the environment, and other factors. Moreover, discoloration is not a panacea, and has its application scope. The effect outside the scope is not as good as a single environment configuration lens. Moreover, the color change needs to be fast enough to be ideal, and at the same time, high-definition technology is needed to meet the vision requirements under various color differences.

No.3 Lenses Color

With the exception of this weather-resistant lens, only one basic lens is needed to cover all weather conditions. But usually everyone will choose two lenses or more to adapt to the light environment brought by different weather. This involves the issue of the transmittance of a lens. There are usually two ways to indicate the transmittance:

VLT notation: Visual Light Transmittance, the transmittance of visible light, expressed as a percentage.

CAT notation: Category Number, which indicates the classification of light transmittance.

The relationship between CAT and VLT is:
CAT-4 = 3% ~ 8% VLT
CAT-3 = 8% ~ 18% VLT
CAT-2 = 18% ~ 43% VLT
CAT-1 = 43% ~ 80% VLT
CAT-0 = 80% ~ 100% VLT

The lens is recommended to choose a coating, usually an iridium coating, the main role is to prevent glare to obtain additional light balance.

No.4 Framed or frameless

Frameless Ski Googles

Most frameless ski goggles have been advertised as being able to increase the field of vision, but in practical use, the scope of the field of vision is more related to the inner frame. The presence or absence of a frame does not greatly affect the visual field, and the lens of the frameless snow mirror is very easy to fingerprint. But frameless handsome! Beautiful! Pull the wind!

At present, most of the frameless frame structures on the market are equipped with more convenient lens switching switches, which are much more convenient than snap-on ones. Generally, only one hand is needed to complete the lens replacement without taking off gloves. However, under the guidance of veteran ski drivers, I personally recommend not to buy a magnetic type, which is indeed the most convenient to use, but the lens is easy to fall during strenuous exercise.

Framed sik goggles also have a system that makes it easy to change lenses, and you will know the benefits of framed snow goggles when you use them in the woods. Even if you accidentally get caught in a tree branch, you will not hurt the lenses. Of course, rich people can ignore.

No.5 Spherical Mirror or Cylindrical Mirror

Spherical Mirror Ski Goggles

Some people say that spherical mirrors, especially large spherical mirrors, have distortion and distortion. In fact, there are also cylindrical mirrors, but generally many snow mirror brands participating in ISPO Beijing 2018 are specifically considering fidelity to eliminate distortion.

The field of view of a cylindrical lens is indeed inferior to that of a spherical lens, but in fact, the processing requirements of cylindrical lenses are higher. To consider vertical flatness, single-board people choose more spherical lenses, while double-board people seem to consider more cylindrical lenses. Professional competitive games usually use cylindrical lenses.

No.6 Safety performance

Ski Goggles

German and American ski goggles products, which pay great attention to this technical indicator, will have impact resistance tests. The tests included dropping metal rods (greater than a pound) from four feet, and a quarter-inch steel shot running at 102 miles per hour.

By resisting the impact of heavy objects at low speeds and resisting the impact of light objects at high speeds, it is also necessary to keep the high-quality materials light and comfortable. Therefore, the value of sik goggles is really not just their appearance, the indicators behind these are very important.
