You may not believe this but Sparkles was given a tongue depressor by the nurse at the eye clinic, told to go home and cut out a bright pic from a magazine, stick it on the tongue depressor, and use that to exercise her eye.
She had to hold it about 18 inches from her face and concentrate on the pic.
When her vision started to go out of focus she had to blink, and then refocus her vision on the pic again.
Apparently, this strengthens the muscle behind
Surprisingly it did help, she found that her vision did improve. Unfortunately she left it too long before getting treatment (she thought it would right itself) and it weakened her other eye, so she needed different treatment.
But try the eye exercises, they may help. Best to get an eye test done, just to make sure it's not something more serious.
Best to be safe than sorry.
Hope this has been of some help?
