HI,
First off, your care isn't quite up to par.
You aren't feeding the right types of bugs, supers and mealies are ok, butthey aren't supposed to be staple/daily feeders.
You NEED to switch to crickets or roaches. these are not easy animals, if that's what youre looking for, you bought the wrong pet.
Your supplements are wrong as well. you need a calcium with no d3 for EVERY feeding, a calcium with no d3 for twice a month, and a multivitamin for twice a month.
If the tongue is injured, then you NEED to see a vet.
I just experienced this with my nosey be about a month ago. He had to have the tongue amputated because it spat the tongue out and it would not go back in his mouth.
You need a good vet who can help you determine the eye thing and this tongue thing, asap.
The eyes could be several things, infection, injury, vitamin a deficiency, etc.
Please go see a vet.
