Maureen answered on 14 Nov 2018:
Your eyes already have a protective layer of tears. These tears are salty but less salty than the sea. A process called osmosis sucks the water away from your eyes when you open them underwater in the ocean, which drys them out and irritates them. That’s why it hurts!
There’s a cool video about it here: https://www.youtube.com/watch?v=y4jdLtPLi2E
