How can I help my fish which was exposed to UV light?

Question

I have installed a UV lamp in my aquarium and had it on for 12 hours.
After that my flowerhorn fish seems to turn pale in colour and his eyes seem to have turned blind. How can I cure my fish? Is the blindness permanent? Please help.

My recommendations
I would highly recommend turning off the UV lamp and replacing it with a LED light that is on for the daylight hours. In nature, the atmosphere cuts most of UV light and gamma radiation that is hurtful to animals.

The explanation
The issue of blindness is I’m sorry to say is incurable. The UV light has already damaged the fish’s eyes so it cannot be undone. I am very sorry for your flower horn fish.
In general, for any creature, UV light is harmful for the eyes, even for humans (this is why humans also shouldn’t look at UV light directly, same goes for the sun).

Conclusion
The fish’s blind eyes are incurable and that UV light is not needed but LED lights are needed. Only have lights on when outside is bright.
