Diving goggles are not allowed in the swimming pool because they are designed for use in deep water and can obstruct peripheral vision, increasing the risk of collisions with other swimmers. 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. **

To change the tip of your pool cue, you will need to first remove the old tip using a tip tool or a sharp knife. Once the old tip is removed, you can sand the ferrule to create a smooth surface for the new tip to adhere to. Then, apply a small amount of glue to the bottom of the new tip and press it firmly onto the ferrule. Allow the glue to dry according to the manufacturer's instructions before using the cue again. It's important to ensure that the new tip is securely attached before playing with the cue. **

It's important to note that these changes are temporary and normal physiological responses to the environment. **

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.
