Because the lens and the seal that surrounds the lens give the protection, it's crucial to know what material swim goggles are composed of.
The materials used in swim goggles nowadays are far superior to those used in the past. In the 1960s, swim goggles were so unpleasant that they could only be worn for a portion of the workout. The rubber straps formed grooves in the swimmer's head and face, and the eye parts dug into their eyes. Swim goggles now come in a variety of materials that aid in durability, comfort, and speed.
Polycarbonate is commonly used for the lenses. While this material is shatter-resistant, it is not scratch-resistant. Polycarbonate lenses are shatter-resistant and UV-protective, making them an excellent choice for swimming goggles. Polycarbonate lenses are a fantastic choice for prescription goggles since they add no thickness while still correcting eyesight and reducing distortion.
It's a light-weight material with a lot of protection. Polycarbonate is ten times more impact resistant than standard plastic or glass lenses. Because the lenses are readily scratched, some have a scratch-resistant coating to keep them clear for as long as possible.
