As an optometry student, I'm having trouble trying to make sense of your question, and that's because it makes no sense at all. "Bad eyesight" does not affect the "brightness" at your retina; rather, it affects the accuracy with which light rays focus on it. Luminance is controlled by factors such as pupil size, not your prescription. And unless you put a tint in your spectacles, glasses will do nothing to affect "brightness at the retina" at all.
