When did Johannes Kepler invent the eyeglasses?

Johannes Kepler did not invent eyeglasses; they were developed in the late 13th century, well before his time. However, Kepler made significant contributions to optics and vision, particularly with his work on the laws of planetary motion and the improvement of the understanding of how lenses work. He is often credited with the invention of the Keplerian telescope in 1611, which utilized a convex lens to enhance magnification.
