Then it was likely a glare I was seeing over her pupil. I would still recommend a visit to a vet. You can take a "wait and see" approach, but if it is an infection, a frog's health can go south very fast. Even if it's only an injury, it may get infected eventually. How you approach this issue is up to you. As a safeguard, try to locate a vet in your area who can see frogs and get some costs. If you can't find one that frankly states it sees frogs, find one that will see reptiles and inquire if they're comfortable examining amphibians. That way, if your frog starts displaying causes for concern, you don't have to worry about finding one. Best of luck, I hope her eye gets better.
