Ski Goggles- Shape
Shape
The lenses of snow goggles are divided into two categories: cylindrical mirrors and spherical mirrors. Cylindrical mirrors are more common in the past, while spherical mirrors are relatively new in the past two years. Spherical mirrors are superior to cylindrical mirrors in several aspects. .
1) Wide field of vision, because the spherical design is more ergonomic.
2) The field of view is larger. Due to the protrusion of the spherical surface, the space between the lens and the human eye is greatly increased, which will bring several benefits. The air coming in from the large ventilation hole has enough circulation space, which will cause it to be difficult to start. fog. The spherical surface increases the distance between the lens and the human eye, and also prevents the steam from the human eye from encountering the cooler lens quickly, which has an anti-fog effect.
3) The spherical lens design is closer to the shape of the human eyeball, so that when the eyeball rotates, no matter what angle the line of sight is perpendicular to the lens, the possibility of parallax is reduced. The lens is farther away from the human eye, and it will be more difficult to touch the eyeball under accidental impact.
4) Of course, in terms of aesthetic effect, the spherical mirror looks cooler. The focusing effect of the prominent spherical mirror makes the surrounding scene concentrate on the lens, and the scene with the lens effect is presented on the lens. Therefore, when buying snow goggles, spherical lenses are recommended first, but spherical lenses are generally more expensive.

5) The ski goggles equipped with spherical mirrors have a wider field of view, and the general thickness is 1.4MM, but the convex parts of the spherical mirrors are easy to be scratched. There are two thicknesses of cylindrical lenses, one is 1.4MM, the other is 0.8MM, and the impact resistance of lenses with different thicknesses is different. The international requirement for the thickness of the lenses of ski goggles is not less than 1.27MM.
The cost of 1.4MM cylindrical mirror and spherical mirror is almost the same, and the impact resistance is also the same. It is a wrong understanding that everyone thinks that the cylindrical mirror is not good when choosing.
