salcada tortoise

Question
eyes are swollen and shut. He can not open them at all

Answer
This can be due to...

Illnesses, such as Respiratory Infections, Herpesvirus, etc.

Injuries from dust or bad substrates

Infestations of fungi

Bad diet, short on vitamin A or trace minerals

Dehydration



Without further information, I cannot guess which of these is the likely cause, and without knowing what caused it, I cannot guess at the treatment.

On the other hand, most of the time, eye infections like this need a vets care to deal with the multiple issues that tend to be involved.
