What does plano mean on my eye prescription?

[Curtis]

I saw my left eyes sign written as Plano on my prescription. What does Plano mean?

[Hugo]

First, as a person who has strong description of my double eyes, I would like to say congratulations to you. At least, one of your eyes is healthy and no strong or even moderate description at all. So, your glasses with no dioptric in your left eye, there's no myopia or hyperopia with it. I don't know the circumstance about your right eyes. I hope it's nothing wrong at all too!

[Reece]

When there is the mark of plano on your eye prescription, it means that your eyes are healthy with neither myopia nor the hyperopia. Based on this explanation, your left eye is healthy. However, what about your right eye? If they are both OK, there is no need for you to wear the eyeglasses to adjust the vision.

Well, as to what you have asked, and according to what I know, plano, here means that the lenses of your left eye are plain, and the surface is smooth. To be sure, you gotta check it out yourself. If you still doubt there are differences between the right and left lenses. You might as well visit the store where you bought your prescription glasses that would be great.
