Image of object formed by a lens on the screen is not in sharp focus suggest a method to get clear focusing of the image on the screen without disturbing the position of the object lens or the screen?
You could insert a second lens in the focal path, between the object and the first lens. The second lens can be designed (or moved) to focus the image on the screen. This is the same function that eyeglasses do for people with poor vision. The second lens, the eyeglasses, are inserted between the viewed object and the lens of the eyes. The second lens is designed to correct the distortion of the eye lens, thus creating an in-focus object on the "screens" of the eyes.
Convex lens uses?
The uses of convex lenses are It is used in microscopes It is also present in our eyes.
Does the thickness of a lens affect the image?
If the lens are thicker it affects the image distance.
What are the Lens that can create a real or virtual image?
Convex lens. Concave lens would give only virtual image for real objects.
Does convex lens produce real image?
No, convex lens does not produce a real image. It reflects the real image
Why do not we see inverted image though eye lens is convex?
our optic nerves invert the image and our brain reads it
Why microscope produces inverted image?
The reason a microscope produces an inverted image is simply due to the number of lenses within it, or more specifically, the number of focal points it has. A microscope with a single lens will have a single focal point. Each focal point will invert the image once, meaning that a microscope with a single lens will produce an inverted image. If you were to add another lens to the microscope and align it the proper distance from the first lens, it would be possible to reorient the image to be right side up. As a side note, our eyes work the same way, the images coming into our eyes are inverted by our own lenses, its up to our brain to flip things right side up.
What is the lens of the eyes?
the lens is what the eye uses to focus an image on the retina.function of the eye lense is is to adjust the focal length of the eye so it can make a real and sharp image of object
Why is the image in your eye produced upside down before it is flipped by the brain?
if there is an object before a lens at a distance more than its focal length and is surrounded by a rarer medium it always forms the image on the other side of lens and is inverted w.r.tobject. our eye lens will simply act like a biconvex lens whose focal length is around 2.5cm . there fore images formed on the retina will be inverted and they are made upright by the brain system.

How does the image form in the eyes?
The cornea and the lens focus the light on the retina - but the "image" you see is formed in the brain from just parts of the light image that exists in the eye.
Why are today microscope called compound scopes?
Because the magnification of image = magnification of eyes piece * magnification of lens.
Convex lens uses?

Does the thickness of a lens affect the image?
If the lens are thicker it affects the image distance.

Explain why an inverted image is seen under a compound microscope?
The microscope you are using is probably old, and it has an odd number of convex lenses between the object and your eye. in addition to enlarging (or reducing) an image, an optical convex lense also inverts the image. If you were to invert the inverted image again, using another lense, then the resulting image will appear upright. So a microscpope with three lenses (most likely the number of lenses in the microscope you are using) inverts the image three times, resulting in an upside-down image. A microscope with four lenses shows an upgright image. That is why modern microscope manufacturers use an even number of lenses in a microscope (and in binoculars).
What is a negative lens is the same as?
If the lens equation yields a negative image distance, then the image is a virtual image on the same side of the lens as the object. If it yields a negative focal length, then the lens is a diverging lens rather than the converging lens in the illustration.
