There is nothing that will prevent glaucoma, but you can slow down its development with early treatment. Therefore, it is very important that you have regular eye exams. Your doctor will perform a series of painless tests -- eye pressure measurements, dilated eye exams, and sometimes visual field testing -- to check for any changes in your eye or in your vision.
