Cloudy eyes are usually caused by something in the water irritating the frog. She seems to be retaining fluid in her body and that could be an internal problem.
You can try doing a 75% water change and gravel cleaning the substrate every day for a week and see if that helps.
Make sure any new water is free of chlorine/ chloramine before it's added to the tank.
The pH is a bit high for them but if the pH has been the same all the time you have had the frog, then that is not the issue.

Any idea what the GH (general hardness) and KH (carbonate hardness) of your water supply is?
This information can usually be obtained from your water supply company's website or by telephoning them. If they can't help you, take a glass full of tap water to the local pet shop and get them to test it for you. Write the results down (in numbers) when they do the tests. And ask them what the results are in (eg: ppm, dGH, or something else).
If the water is really hard, she might have kidney problems due to the high mineral content in the water.
That's about all I can offer. Hopefully a herpetologist will see this and be able to offer more advice.
