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 cornea is the transparent, dome-like structure on the front part of the eye. The cornea gives the eye two-thirds of its focusing or refracting power. One-third is produced by the internal crystalline lens. The cornea functions like a camera lens, helping to focus light coming into the eye onto the retina. The cornea is also filled with nerves that alert us to irritations that could potentially harm our vision and eye health. The cornea is a remarkable piece of tissue made up of specialized cells.
