Each of your eyes has a lens in it. This lens can change its shape and hence its focal length. By changing the focal length you are able to focus on an object based on how far away it is from you. For this problem you will determine the maximum focal length of your eye. A. To determine the maximum focal length of your eye you need to establish how far you can see under ideal conditions (no fog, an...

Each of your eyes has a lens in it. This lens can change its shape and hence its focal length. By changing the focal length you are able to focus on an object based on how far away it is from you. For this problem you will determine the minimum focal length of your eye. A. Hold an object out in front of you at arm's length. Close one eye and bring the object towards your eye and determine how...

There are three types of conditions by which the eye can not focus properly; myopia, hyperopia and astigmatism. Here we will explore only myopia and hyperopia. In myopia (for various reasons) the image within the eye focuses on a point in the vitreous humor and not in the retina. This causes the eye to be unable to correctly focus on distant objects. In hyperopia (for various reasons) the image focuses on a point farther away than the retina outside the...

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...
