Answer 1

fill in the blank with theses words: concave longer larger curved convex length clearly object thick shape lens retina less refracting virtual cornea astigmatism

Lenses are made of transparent material and have a _________ surface. A convex lens has thin edges and a _______ middle. Another type of lens is thicker at the edge than the middle and is called a ________ lens. All lenses work by _________ light. Parallel rays of light are refracted toward each other and brought to a focal point in a ____________ lens. Light is refracted both when it enters and leaves a ________. The amount of refraction depends on the change of speed of light as it passes through a material and on the _________ of the lens. In a convex lens, the type of image formed depends on the position of the ______ and the focal length of the lens. When the object is more than twice of the focal length from the lens, the real image is smaller than the object and ________. If the object is between one and two focal lengths, the image is ______ than the object and inverted. When the object is between the lens and the focal point, the image is larger and upright but is a ________ image. Concave lenses are not able to produce real images and are used with convex lenses to create a __________________ focal length.
The light we see enters our eyes through the transparent covering of the eye called the _______. The light then passes through the pupil and converges on the back part of the eye called the ______. Images are properly focused on the retina by the convex lens in the eye, which is controlled by eye _________. To focus images of distant objects, a longer focal ________ is needed. To do this, the muscles relax allowing the lens to be___________ convex. People are farsighted when they can see things far away________ but have fuzzy vision at close range. To correct this problem, a ________ lens is used. A ____________ lens is used to correct the vision of a nearsighted person. And eye problem caused by an unevenly curved cornea is ____________.
