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.
back toric contact lens A contact lens used to correct corneal astigmatism in which the surface of the lens facing the cornea is not spherical but toroidal in order to obtain a good physical fit on the cornea. To create better stability of the lens on the eye it usually incorporates a prism ballast. See ballast.
The lens is a clear part of the eye that helps to focus light, or an image, on the retina. The retina is the light-sensitive tissue at the back of the eye. In a normal eye, light passes through the transparent lens to the retina. Once it reaches the retina, light is changed into nerve signals that are sent to the brain. The lens must be clear for the retina to receive a sharp image. If the lens is cloudy from a cataract, the image you see will be blurred.
