The Prince's relationship with Anne, Edward and Andrew has been at times loving and at times tempestuous-but, like any other family, their paths have diverged with age.omments. The baptism of Prince George last month was notable not only for a lack of royal godparents â Zara Phillips being the only one â but a lack of royalty in general. The ceremony was a tight affair, the Duke and Duchess of Cambridge having invited 22 guests, six of them from the Royal Family.
The lens, like the lens of a camera, opens and shuts to allow light to reach the retina to focus an image. With age, the lens loses the function to refract light to bring images into focus. Disease can rob the lens of its function to work with light. Many conditions can be corrected with surgery.
The Lens. The lens is composed of transparent, flexible tissue and is located directly behind the iris and the pupil. It is the second part of your eye, after the cornea, that helps to focus light and images on your retina. Because the lens is flexible and elastic, it can change its curved shape to focus on objects and people that are either nearby or at a distance. The lens provides 25-35% of your eye's focusing power. The ciliary muscles, which are part of the ciliary body, are attached to the lens and contract or release to change the lens shape and curvature. The lens becomes more rounded to focus on near objects (see Figure 1): Fig. 1: A more rounded lens can focus on near objects.
