I too am sorry for your loss, but going through your posts you seemed to have handled him too much, ran out of crickets at one time, and then did not get him to the vet. He may not have even had an eye problem, but just may have been in the process of dieing. I am no expert, but do realize the time and money it takes to maintain most any animal. Let it be a learning process and plan carefully both time and money before taking on another responsibility.
