Quick Answer
Your improvised goggles should have a diameter of approximately 7-8.5 inches to provide maximum coverage for your eyes, protecting them from snow blindness caused by UV radiation.
Measuring Your Goggles
To create effective improvised goggles, measure the distance between the centers of your pupils. This distance is approximately 4-4.5 inches. To account for the size of your face and the space for the gasket, add 2-3 inches to this measurement. This will give you a rough estimate of the diameter of the goggles.
Materials Selection
For the lens, use a clear plastic sheet or a piece of transparent polycarbonate. You can use a plastic container or a piece of plexiglass as a base. Attach the lens to the base using a strong adhesive, such as hot glue or epoxy. Make sure the lens is centered and securely attached.
Assembly and Fit
Apply a thin layer of petroleum jelly or lip balm around the edges of the goggles and attach a gasket or a piece of cloth to create a seal. This will prevent snow and wind from entering the goggles. Place the goggles over your eyes, ensuring a comfortable fit. You can adjust the gasket or the goggle’s size to achieve a snug fit.
