When we are looking through a magnifying glass from a position far away from the focus , a real image is formed which is inverted.This inverted image cannot be obtained on the screen.Hence we see the image upside down. However if we look through the magnifying glass at a position between the optical centre and focus a virtual,erect and magnified image will be formed.This can be obtained on the screen.

Why don't you see things upside down if that how it enter your eyes?
It is true that the images formed on your retina are upside-down. It is also true that most people have two eyes, and therefore two retinas. Why, then, don't you see two distinct images? For the same reason that you don't see everything upside-down. One of our most remarkable tools - the brain - is hard at work for us at this task. Processing visual information is a complex task - it takes up a relatively large portion of the brain compared to other senses. This is because your brain performs several tasks to make images 'easier' to see. One, of course, is combining the two images, which is helped by the corpus callosum, the tiny part of your brain which joins the two big hemispheres. The other part is handled in the optic part of your brain itself, and part of its job is to make images right-side-up. It does this because your brain is so USED to seeing things upside-down that it eventually adjusts to it. After all, it's a lot easier to flip the image over than it is to try and coordinate your hands and legs with an upside-down world! As a result, though, it is believed that for the first few days, babies see everything upside-down. This is because they have not become used to vision. Your brain CAN be retrained though. In one psychological study, participants were asked to wear inverting lenses - lenses that invert the image BEFORE they get to your eye, so that when your eye inverts it, it's right-side-up. At first, everything appeared upside-down to the participants. But, after a few days, people began to report that everything appeared right-side-up! As a second part of the study, the people were asked to take the glasses off. Because they were now used to the lenses, their NORMAL vision appeared upside-down!! Within a day, though, their vision returned to normal. The reason you don't see everything upside-down, then, is simply because it's easier to think about right-side-up!
What part of the eye focuses the light that comes through the eye?
The answer to this question is the retina .......... It's the retina because everything is upside down, bends, goes up to the brain and flips it around........and that is why the light is always focused on the retina

How do you build telescope?
To assemble your telescope, do the following:Get the two magnifying glasses and a sheet of printed paper.Hold one magnifying glass (the bigger one) between you and the paper. The image of the print will look blurry.Place the second magnifying glass between your eye and the first magnifying glass.Move the second glass forward or backward until the print comes into sharp focus. You will notice that the print appears larger and upside down.Have a friend measure the distance between the two magnifying glasses and write the distance down.Cut a slot in the cardboard tube near the front opening about an inch (2.5 cm) away. Do not cut all the way through the tube. The slot should be able to hold the large magnifying glass.Cut a second slot in the tube the same distance from the first slot as your friend wrote down. This is where the second magnifying glass will go.Place the two magnifying glasses in their slots (big one at front, little one at back) and tape them in with the duct tapeLeave about 0.5 - 1 inch (1 - 2 cm) of tube behind the small magnifying glass and cut off any excess tube remaining.Check to see that it works by looking at the printed page. You may have to play slightly to get the exact distances between the two glasses right so that the image comes to a focus

What is the custom of turning a glass upside down on the table?
Can you be more specific as to who does this?If you mean glasses already on the table when you are seated in restaurants, having them upside down keeps dust from falling into the glass and allows them to drain if they weren't QUITE dry when placed there.
When might you think you're upside down?
When your nose runs and your feet smell. Also, originally when your eyes see things, they first see it upside down, then through a process turn it into the way you see it. However, one of the reasons people might need glasses can be because the process in which the eyes turn what they originally see into what you see works differently.
