When choosing a frame
When choosing a frame, it is important that it suits your face shape. It is also important that it fits snugly against your helmet and does not create a gap, as cold can then get in at your forehead and cool you down. The ski goggles should also not pinch anywhere. When it comes to goggle size, you can start by considering the size of your head and helmet. If you have a small head and helmet, you should look for goggles with a slightly smaller frame and vice versa. Ski goggles that have a thin frame or a completely hidden frame provide better peripheral vision, which can be beneficial in most situations.
If you wear glasses when skiing, you can advantageously use OTG (Over-The-Glasses) goggles. This type of frame is designed to accommodate a pair of glasses underneath. Some "regular" frames can also fit glasses underneath, it simply depends on the model and size of your glasses. OTG frames have a cutout in the foam edge for the eyeglass temples and are also often deeper than regular ones.

The shape of the lens
The shape of the lens indicates how the lens is curved. The lens is either spherical or cylindrical.
Spherical lenses are curved both vertically and horizontally. This means the lenses provide better peripheral vision and there is less risk of dazzling reflections. In addition, fogging does not occur as easily with these lenses as more air can fit between the lens and your face.
Cylindrical lenses, on the other hand, are curved horizontally but are flat vertically. This lens shape is cheaper to manufacture, which means a lower price.

The color of the lens
The colour of the lens can be more important than you think. It's not just about appearance, but also about light transmission and contrast enhancement. When it comes to light transmission, you should always check the VLT, which shows the percentage of light that passes through. The higher the number, the more light the lens lets through.
For example, if it's cloudy, foggy, or the weather is changing, you should have ski goggles that let through a lot of light but also enhance contrast. Generally, clear, yellow, pink, or light blue are colours that are usually well-suited for these weather and light conditions. In these types of weather and light conditions, a lens with a light transmission (VLT) between 60–90% is usually good.
If it's very sunny, your lens should have lower light transmission. Overall, lenses that are brown, grey, black, gold, or orange are preferable in these weather and light conditions. These lenses often also have some form of mirror treatment on the outside. In this type of weather and light condition, a lens with a light transmission (VLT) between 5–20% can be good.
If you want to buy a lens that can serve as an all-round lens, generally speaking, dark pink and orange lenses are best for this.
You can either have different lenses to switch between, or you can have two different pairs of goggles to use depending on the weather. How you go about it is a matter of taste. An extra lens is more convenient to carry but is more cumbersome to remove and attach than simply changing goggles. When you buy certain ski goggles, you get two lenses included, which can be good to know.
