Is it too late to change my career to be an Optometrist?
I dont think it's never to late for anything...
Do your research and see if it's something you would really enjoy.
Do you have a passion for it.? Can you live on your savings as you go through the training.?
Sure it's worth it if you think it is...
If you think it's a rewarding field then go for it..if you don't you will never know.
