Additionally, diving goggles are not necessary for swimming laps or recreational swimming in a pool with clear water. The use of diving goggles in a swimming pool can also create a safety hazard if the wearer dives into shallow water thinking it is deeper than it actually is. **

Using a diving mask instead of swimming goggles can provide a wider field of vision and better visibility underwater. Diving masks are designed to create a watertight seal around the eyes and nose, preventing water from entering. They also typically have a nose pocket for equalizing pressure while diving. However, diving masks may be bulkier and less streamlined than swimming goggles, which could affect comfort and performance while swimming laps. **
