if convex lenses projects upside down images on the retina how come we dont see things upside down?

yes. this is a interesting question. the same process happens in you eyes which is also a lens that convex lenses projects upside down images, your eyes then after getting this Image it is transformed in the form of wave impulse and then sends to the spinal cord. this image is carried out again as a form of an object to be researched in your brain as a new object or an object that you old knew. Reason why when you see some thing for the first time you do take much time finding it position and what it is by changing position and recording as much information as you can for the next time you meet the same object .so when you get to know that this object is positioned this why then automatically it is recorded in you mind. so Then Images is really upside down after being returned in the normal position by your main commander( impulse receiver and impulse record)as it is in you hand or it applies in front of you.

It's nearsightedness.  The convex lens formed by the eye's own lens and the curvature at the front of the eyeball determines the focal length.  A concave lens corrects the problem by increasing the focal length.

3D movies can be made using polarized light.  The projector is actually showing two frames, one polarized vertically, and the other polarized horizontally.  When you where the polarized glasses your right eye sees only the frame that is polarized for the right eye, and the same with the left eye.  This allows them to project two images (as your brain would see them naturally) at the same time and have you be able to properly interpret the 3D perspective.

If you're talking about a lens in the shape of a contact: distortion or "pincushioning" of the center of your field of vision. It increases the peripheral range somwhat.\n\nif youre talking about with a microscope: severe limitation of view range, and the item you are focusing on has much sharper focus, and you can see details of its surface...

a double convex lens will magnify, i can't remember which ones reduce size, but i'm guessing some sort of concave lens, and lenses REFRACT light, while mirrors REFLECT light.

You can really only see images that are focused onto a small little center on the back of your eyeball.  When your lens becomes distorted, the light is reflected onto the wrong area.  Normally all light converges on this area and you see 1 image.  The images you are seeing are overlapping and appear blurry to you.

There are actually 2 ways to see Magic Eye pictures (also called random dot stereograms).  One way is with your eyes crossed and the other is with them uncrossed, but I don't remember which way gives you which image.  It's usually easier for people to do it one way over the other.  And then there's people like me who have to work really hard to do either.

An upright microscope looks down at the stage, slide and specimen, and transmitted light travels upward from a mirror located below the stage. An inverted microscope does the opposite. Its optics include a prism so that a person looking down into the microscope sees the view from below the stage. An advantage of the inverted microscope is said to be the ability to view live specimens in a deep covered container (see ref.). The short working distance of the typical objective lens prevents such viewing in the upright microscope. (However some change in the inverted microscope's objective is needed to accommodate container thickness.)

A conver mirror is diverging in nature.Ligh rays incident at its extreme corners gets diverged following laws of reflection.Hence if we draw the diagram we can clearly understand that the reflected rays follow a wider path.While in case of a plane mirror the divergence is not so large.The credit to this can be given to the cuvature in convex mirror

It does neither. It just reflects a laterally inverted image which has nothing to do with left-right or top-bottom.

The image which is formed on the retina through the lens of the eye is very similar to a pin-hole camera, the image is reversed both horizontally and vertically. The lens of the eye is purely used to focus this images.

The lens in your eye may be too strong and thus focus the image of the outside world in front of your retina, or it may be to weak and focus the image behind the retina.  By placing a lens (glasses) in front of the eye, we can compensate for this by ensuring the image falls exactly on the retina, which allows for good vision.

The same reason why a pinhole camera works.  As light passes therough the pinhole, it refracts and is focused.

It's not reversed, you only think it is. The left side reflects to the left side, the right side reflects back to the right side, same with top and bottom.

Jayboo what the heck are you talking about?\nI think you must have totally skipped the day that your junior high biology class was studying the eye.\nDo a search for cones and rods.\n\namateur astronomers call looking a bit to the side of a dim object "using averted vision" but there is more to it than just rods -vs- cones. http://vegas.astronomynv.org/Tutorials/avertedvision.htm\nThis website has a nice article detailing  averted vision.\nhope that helps.

sorry but havent got an answer for you however you did succed in making me laugh for a second so thank you. i guess you could say the same about bats, they are blind but only come out at night....Whats the difference lol. Do you think they are also aware that they hang upside down????

As you know, the 'bending' of light changes its direction.\nSame thing happens to sounds - you can hear sounds from around a corner.
