Oh no what is this white eyes?

I was wondering if anyone can help me my betta went from being fine to his eyes turning white any ideas thx.

Cloudy eyes usually mean one of two things. Either it is a bacterial/fungal infection or their eye got injured somehow.

For both cases, usually doing a few extra water changes and keeping the tank extra clean will clear it up (for me anyways). Sometimes meds are needed though. Something that treats bacterial+fungal infections should do the trick.
