Swimming goggles are necessary safety accessories for the swimmers or those involved with other water sports. The goggles protect the eyes from the chlorine or other chemicals present in the water and provide a clear vision. Few models of goggles also protect the eyes from harmful UV rays and sunburn. Swimmers can comfortably see through the goggles and open them underwater. Swimming goggles also prevent the eyes from any pathogens such as bacteria, pond scum and algae from outdoor water. Swimmers generally prefer clear lenses such as amber, yellow and blue lenses for better visibility. However, the blue lens maximizes the underwater visibility.
Lens - The clarity of lenses is crucial for the vision of the swimmers a lot. The clear lenses don’t provide any protection against the sun but are ideal for indoor swimming. The lenses also come in various colours from darker shades like blue, black and grey to other rainbow colours. The mirrored and polarized lenses, on the other hand, have the reflective metallic coating in silver, gold or multicoloured. They are ideal for outdoor swimming and provide clear underwater vision to the swimmers.
Straps - The straps function in holding the lenses in the right position. They are classified as follows -

In the 14th-century, swimming goggles were first invented in Persia. The traditional goggles were constructed with polished tortoise shells having good transparency. The pearl divers primarily used them and further used and gained popularity in the Middle East and other countries.
Later, the Polynesian skin divers manufactured wooden goggles with deep frames. The modified goggles can trap air to maintain visibility. In the 1950s, the first rubber goggles with double lenses were used by some open water swimmers. In 1969, modified new versions of goggles produced by Tony Godfrey came into light. The goggles were regarded as "Godfrey Goggles" and were made of polycarbonate being light-weight and shatter-resistant.
In modern times, the goggles are entirely revolutionized. The modern swimming goggles provide better hydrodynamic drag, UV protection, anti-fog and are available in a plethora of sizes and colours.
