A person is farsighted and has near point of 50 cm. Retina is at a distance L = 1.7 cm. When wearing contact lenses and reading a book 30 cm in front of the eye, what is the object distance for the lenses? What is the desired image distance? Is the magnitude of the image distance a minimum, maximum, or the only acceptable image distance? Find the focal length and refractive power of the contact lens that will fix this vision. Draw a ray-tracing to show the formation of the image by the contact lens.

The uncorrected eye. For the following questions, assume that the distance between the eye lens and the retina is 1.70 cm. In other words, since the image is always formed on the retina, the distance between the lens and the image is always 1.70 cm. Also note that, as is seen in the ray diagram, since the eye lens is converging and the image is on the opposite side of the lens compared to the object, the image is always...

Contact lenses are placed right on the eyeball, so the distance from the eye to an object (or image) is the same as the distance from the lens to that object (or image).

A farsighted eye is corrected by placing a converging lens in front of the eye. The lens will create a virtual image that is located at the near point (the closest an object can be and still be in focus) of the viewer when the object is held at a comfortable distance, usually taken to be 25.0 cm.25.0 cm. If a person has a near point of 49.5 cm,49.5 cm, what power reading glasses should be prescribed to treat this...

A. The human eye 1. Whenever a normal eye forms an image, the image distance will always equal the distance from the cornea and eye lens to the retina (~25 mm), regardless of how far away the object is located. Explain why the image distance cannot change. 2. If the image distance must change, then what intrinsic property of the eye lens must change in order for the eye to focus on objects at different distances? Hint: read the Introduction....

2. Correcting vision: quantitative. Corrective lenses work because the lens bends light such that it, combined with the eye itself, light forms a clear image on the retina. Another way to think about this is that the corrective lens (glasses) form an image of the object at a location where the eye can see clearly without corrective lenses. For a nearsighted person viewing an object very far away (object at infinity), the lens corrective lens creates an image at the...

A patient's far point is 135 cm and her near point is 15.0 cm. In what follows, we assume that we can model the eye as a simple camera, with a single thin lens forming a real image upon the retina. We also assume that the patient's eyes are identical, with each retina lying 1.95 cm from the eye's "thin lens." (a) What is the power, P, of the eye when focused upon the far point? (Enter your answer in...

A concave lens has a focal length of magnitude 10 cm. It is placed a distance of 25 cm from a concave mirror with a focal length of magnitude 15 cm. An object is set a distance of 22 cm in front of the lens. The observer is at the same location as the object, so the light from the object goes through the lens, reflects off the mirror, and comes back through the lens to the observer. Draw the...

Q2. Lenses and the Eye An object O is positioned 3.5 m from a lens of focal length f = -1.5 m as shown: Copy the diagram and draw in: the path of a parallel ray from the top of the object through the lens; the path of a ray through the centre of the lens; and hence the location of the image. Calculate the image distance di from the lens. Mark this distance on the diagram in a). A...

1a) Prove that, for a concave mirror, the ratio of object to image distance is the same as that of object to image height 1b) The normal human eye can focus on objects at distances ranging from 25 cm to infinity. The distance from lens to the back of the retina, where the image needs to be formed, is about 1.7 cm. What is the range of focal lengths of the lens of the eye?
