You should have regular eye checkups. Things like glaucoma, macular degeneration, detached retinas and cataracts can sneak up on you.
Without a professional exam, you will just not know and you can end out blind.
The professionals can offer options and help deal with issues if you are seen early and often.
One additional note: I had very bad astigmatism in both eyes, and after LASIK, they are gone. Not all have this option, but it worked for me.
