Seurat was an impressionist painter who painted using little dots of color--- when an observer steps back away from the paintings, the colors of the dots "blend" in the eye and the observer perceives a continuous picture. Seurat's dots were about 2 mm in diameter, with a separation between the dots also about 2 mm. The color sensitive cells in your retina have a sensitive area with a diameter of about 1?m and you can assume they have a separation...

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...

1) The distance from the lens to the retina is 3.1 cm, what is the effective focal length of the lens when staring at an object infinitely far away? 2) An object is moved to 40cm from the eye. What must the focal length of the eye be to focus the image on the retina? 3) In the near sighted eye, images focus before hitting the retina. Suppose the focal length of the lens is 1.9 cm, while the distance...

1. Consider a 1 mm bug located at your nearpoint, 25 cm away from your left eye. 1a). Sketch the object, lens and image positions if the object is 1 mm in size and the image distance between the retina and lens in your eye is 1 cm. 1b). What focal length for your eye lens is needed to focus the bug’s image onto your retina? 1c). If you insert a convex magnifying glass 6 cm away from the bug,...

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....

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...

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...

Problem 1 What is the power of the eye when viewing an object 50.0 cm away? (52.0 D) Suppose a certain person’s visual acuity is such that he can see objects clearly that form an image 4.00 μm high on his retina. What is the maximum distance at which he can read the 75.0 cm high letters on the side of an airplane? (3.75 km)

Part (a) What is the power in D of the eyes of a woman who can see an object clearly at a distance of only 7.5 cm?

The maximum resolution of the eye depends on the diameter of the opening of the pupil (a diffraction effect) and the size of the light receptor cells (rods or cones) on the retina. The size of the retinal cells (about 5.0 μm in diameter) limits the size of an object at the near point (25 cm ) of the eye to a height of about 50 μm . (To get a reasonable estimate without having to go through complicated calculations,...
