yes picture would help, however cloudy eye in a baby could mean one thing ( 99% probability) - infection, the next thing would be is to figure out why it has happen, so please post your answers to "the trouble in the enclosure" here.
for eye infection that is what you need to do:
- place a frog in a hospital set up - wet paper towels covering all 4 sides of the enclosure and a bottom.
-make sure that temps are still staying in a correct range, but humidity a bit lower then usual.
- get melafix ( sold in fish section), prepare the solution according to the instructions on bottle, use it for everything, pepertowels, soak a frog in that too, 2 times a day (warm water up to a frog chin). While melafix works very well for mild eye infections, often it is not enough, so i would use it for a few days and see what is happening, if you see infection is progressing or not getting better in 2-3 days, plan on seeing vet asap. I'd schedule an appointment for Monday, you can cancel it if a frog is all better by then.
