It's been hard for me to take care of my two RES turtles, but I've tried. And I recently got some extra stuff, like a new waterfall filter, this aquatic plant which is supposed to help control algae in the tank and an extra lamp for my Exo Terra 100W Daytime Heat Lamp
So, anyway, I only had one lamp for a couple of months and I've been trying to keep my Repti Glo 5.0 and the Exo Terra 100W on for a couple of hours a day each. Then yesterday, when I got all of this, I noticed one of my turtles wasn't really paying attention. He keeps bumping into everything, can hardly see the food and his left eye is now blank. He's always basking, btw, all the time. The other one is almost always swimming.
Now his left eye has a redish/white tone to it, it is definitely not the eyelid, and he doesn't seem to get any kind of response from that eye.
Reading a bit I saw something about UVB bulbs burning turtles' eyes in the long run, specially if they're not good anymore. And I didn't know most of them are even harmfull after 6 or 12 months =/ I've had this bulb for about 16 months now, so I don't turn it on anymore
Is there anything I could do for my turtle? I can order anything from Amazon/eBay but there are no Reptiles Vets near my area, nobody knows anything about turtles here.
I'll include some pics, both eyes, and also my tank so you can see it


This is his other eye, which seems fine

This is the set up. I have some medium sized rocks but they're getting cleaned. The Heat lamp goes on automatically at 2pm and goes off at 8pm.

Bonus pic. I just got this tattoo on saturday. Left turtle (Dark one) is the little one who's always jumping when I get the food. Right side turtle is the one I made this post about, he's always chilling enjoying some sun
