Map Turtle seems to have issues opening his eyes.

We have six turtles in a large pond inside our house. Several of them are painters, one is a red ear and then we have Bowser, the map. She seems to be eating fine and we have proper basking areas for the turtles, but for some reason her eyes look swollen. It's like she can't open them and she tries so hard especially when we pick her up. She can get a peek open but then closes her eye again. It looks like she's blinking with her eyes closed... I don't know what to do for her. It seems like she is in pain and I want to help so bad.. does anyone know how I can help her? The eye looks like it has a white/clear lid over top that she has trouble opening.. not sure how else to describe it.
