The answer is yes. If you have a perfect vision, it just means you don’t need to wear glasses. However, it doesn’t mean you don’t have any other eye issues such as glaucoma, cataract, etc.
My mom always told me that eye is the window into our health. Many diseases could be reflected on our eyes. For example, cardiovascular health issues could be apparent during an eye exam. You should check your eyes every now and then.
I also have a perfect vision and never wear glasses, but I do eye exams once a year at least. Your eye doctor will offer you some advice on how to protect your eyes. So trust me, it is necessary indeed.
