If you can describe the terrarium and the conditions better for us, we can give you better advice.
It's a 20 gallon upright with frontal opening, front vent and wire mesh top. The eye is bigger today but he ate 2 crickets. Should I use some type of eye drop? the nearest reptile dr. is located about 2 hours away. The other frog in the tank is doing well though.
