Assistant: Some people are able to see clearly underwater with just their eyes, without needing an extra device such as goggles.  However, for some people's eyes, being underwater makes things appear blurry.  With a set of goggles, it's easier to see clearly in the water.


Human: Why do I need goggles to see underwater, but other people don't?

Assistant: Ah, that is an excellent question! While the human eye is generally able to adapt to underwater conditions without equipment, the ocular lens gets weaker and cloudier under water, which distorts vision and prevents complete focus. This can lead to eye discomfort, eye damage, and permanent vision impairment if performed frequently without appropriate ocular protection. Therefore, it is very important to use swim goggles or other protective equipment while swimming or snorkeling underwater, in order to comfortably and safely view the aquatic environment.
