My 7-year-old son just asked me this.

Because it's tough for dry eyes to blink.
The water acts as both a lubricant and an irrigating rinse to flush out any dust or trash that may get into our eyes.

the moisture is lubrication and also it brings oxygen and nutrients to our cornea which is the clear bump on the eyeball, if you look at one from the side. In order to be clear, our corneas do not have any blood vessels so it needs a constant supply of tears to oxygenate and feed it nutrients. The tear fluid is also loaded with antibacterial agents to minimize infection.
