I had recently seen a case like this where the lfs bought in 2 oscars 8-9" that had slime coats coming off and both eyes gone completely cloudy. They were kept in a 3ft tank with 2 other oscars and 4 blood parrots yup 8 fish in a 3ft tank. The tank was at the owners shop and he only fed the tank but dint do wc for almost 3-4 months.What the lfs told me was all the others died one by one and still the owner don't change water. When only these two remained he called the lfs to take them as he thought they got ugly and they were not dying yet so he just gave up on them.
Now for the treatment. The guy at the lfs gave them 60% wc everyday for almost 9-10 days nad he would add in some salt in the water. They are still not gully recovered but they now swim normally and eat like normal oscars. They sulked and stayed at the bottom for almost 2 days at the lfs .
So yeah until you don't find out the root cause , WC won't harm.

The requested information (maintenance routines, water parameter values) are needed.
Regardless, just from the looks and considering the info given, it seems clear that -
1- The tank is too small for those fish, if not currently (I think it is), then very soon.
2- Aquarium hygiene, including but no limited to frequency and volume of water has been insufficient.
There are serious bacterial/fungal infections on eyes and fins (one fish more than the other). Even if these started merely from physical injuries, secondary infections have settled in, particularly on the eyes. Any hope of permanent cure will have to include both medicines (not before additional information is available), and a major improvement in aquarium maintenance. I seriously doubt either one alone will do the trick. As bad as it may sound, much of the problem is almost certainly reversible, even if some scarring remains - so it is possible to save them. Good luck!

Yes the water is cycled at least once every hour, and we don’t know the PH yet, we have to bring a sample to our pet store. For now we are just doing a 25% water change, cleaning the filter and decorations
Yes they are nearing the point of outgrowing this tank, we were waiting a little longer though to move them into 75 gallon. Unfortunately my father slacked severely with cleaning the tank and water changes, last time a water change happened was well over 3 months ago. After this scare, he told me we will start doing it every 2 weeks. We are doing a 25% water change right now and cleaning the filter. Tomorrow we will test the water at our local pet store and I’ll get back to you guys with the results and try to seek further help/advice from there.
Oh, cleaning the filter is the first thing he did as it’s been months since it’s been attended to. He won’t do anything larger than a 25% water change because he said that more than that is dangerous
Tell him to do more Of a water change. It doesn’t do anything. He needs to use water conditioner. Did he clean the whole filter?
A tank with large fish like that needs more frequent water changes than every two weeks. I have a moderately stocked 150 gallon and I change 75% every 3 to 4 days.
