Do you have gles or do you have perfect vision?

If you do have gles, are you nearsighted, farsighted, or do you have astigmatism? If you have perfect vision... CONGRATS (I don't mean that in a bad way) To everyone: please also tell you gender. In case your wondering, I'm doing a Science Fair Project (How does gender effect vision) and I need to so a survey for it. Thanks in advance
