Yes even when you have great or perfect vision it's still a good idea to go to the eye doctor at least every 5 years or so just to make sure your eyes are healthy.
Some people go to the eye doctor every 2 years when they are under 60 but for me I go to the eye doctor every 5 years or so just to be sure my eyes are actually healthy.
Once you're over 60 years old it's recommended to have year eye checkups at an eye doctor and see the eye doctor every year.
Unlike your other parts of your body and seeing a regular doctor yearly or every 6 months or so there's no need to actually see an eye doctor as often if you have good vision.
But if you want to see an eye doctor more often you can do so.
Every 5 years for an eye doctor visit is enough for me and I pay out of pocket for the eye doctor visit.
