They were the first devised by Benjamin Franklin in 1784. The first eyeglass frame temples were made by Spanish craftsmen in 1600's. They affixed ribbons of silk or strings to the frame and loop them over the user's ears. The new types of eyeglasses carried out to China by Spanish and Italian missionaries.
The Asteroid Belt is located between the orbits of Mars and Jupiter: so it can only be one of the two planets that is the closest to it. Mars is located approx 250 million km from the Sun and Jupiter - 750 million km from the Sun. Mars is closer: so the correct answer is: Mars is the planet closest to the Asteroid belt.
For reference, our own asteroid belt lies at about 3 astronomical units from the sun, and Uranus is roughly 19 astronomical units away. One of the two possible planets previously identified around Epsilon Eridani, called Epsilon Eridani b, was discovered in 2000. The planet is thought to orbit at an average distance of 3.4 astronomical units from the star -- just outside the innermost asteroid belt identified by Spitzer. This is the first time that an asteroid belt and a planet beyond our solar system have been found in a similar arrangement as our asteroid belt and Jupiter. Some researchers had reported that Epsilon Eridani b orbits in an exaggerated ellipse ranging between 1 and 5 astronomical units, but this means the planet would cross, and quickly disrupt, the newfound asteroid belt.
