How to fit glasses comfortably in snow goggles has always been a painful hassle for myopic people. Some people choose soft frame snow goggles that are compatible with frame glasses, but fog and discomfort can often ruin your skiing experience; some people choose contact lenses, but not everyone is used to wearing contact lenses, and the oncoming wind while skiing Also often blowing people uncomfortable.

OTG snow goggles

Over the Glasses (OTG), also known as OTG snow goggles, is a universal solution for people who want to wear both frame glasses and ski goggles. Compared with ordinary snow goggles, OTG snow goggles have a larger space between the lenses and the glasses, and the sponge at the frame is thicker, so as to avoid squeezing the frame snow goggles worn inside. In addition to wearing comfort, OTG snow goggles have to consider a more important issue - ventilation and anti-fog. To this end, snow goggle manufacturers will add additional ventilation holes for OTG snow goggles, and some have adopted fans or electronic heating and defogging systems.

How to avoid fogging when wearing glasses inside snow goggles

We must understand that the main cause of fogging of the lens is the air temperature difference inside and outside the snow goggles, so it is best to pay attention to the following points: 1. Do not pull the snow goggles to the forehead or helmet from time to time, otherwise the hot air will quickly pour in and cause fogging . 2. When going from indoors to outdoors, don't rush to put on snow goggles, let the face and snow goggles cool down properly. 3. Do not put the face protector on the lower edge of the snow goggles, otherwise the hot air breathed out will easily be poured into the snow goggles and cause fogging. 4. After daily skiing, take the goggles out of the protective case and let them dry in a dry place. 5. When the snow goggles are fogged, do not wipe the moisture on the inside of the lens at will, which may damage the anti-fog coating on the inside of the lens.

Snow goggles with built-in optics

If you find the OTG mode of wearing snow goggles too cumbersome, snow goggles with built-in optical lenses are also a solution. The optical lens is built into the inner side of the snow goggle lens, and a special anti-fog coating is used at the same time, just like the swimming goggles with prescription, it adopts a one-piece design. The advantage of this design is that you don't have to worry about the OTG goggles with few styles, any snow goggles on the market can be compatible with built-in optical lenses. The disadvantage is that the built-in optical lenses are more expensive, and when you take off the snow goggles, you have to replace the spare glasses, which is relatively troublesome.
