“Is it permissible to see blurred inappropriate images?”
That almost sounds oxymoronic. If the images are truly blurred and you really cannot see without your glasses, then you are NOT seeing inappropriate things. The question is if you are permitted to go there altogether! Are you going into the water where there may be females swimming nearby? Ask a shailah.
I think your best bet is to get that thing that horses wear on their heads to prevent their peripheral vision from seeing something distracting. Oh yeah, they are called Blinders.
