| silicone | Any of many polymers made up of alternating oxygen and silicon atomscombined with other organic groups. Silicone can be an oil, grease, gelor plastic, but all forms are resistant to heat, water and will notconduct electricity. It is used for a huge number of uses in industry (lubricants, paints, adhesives, coolants, etc.) Silicone is used inmedicine to replace body parts, and its use in breast implants has comeunder fire because there is evidence that these appliances may leak, andfurther evidence that leaked silicone may cause autoimmune disorders. (09 Oct 1997) |

| silicone elastomers | Polymers of silicone having properties similar to those of vulcanised natural rubber, namely the ability to be stretched to at least twice their original length and to retract very rapidly to approximately their original length when released. (12 Dec 1998) |
| silicone implant | Implant composed of silicone; common form of breast implant for augmentation. (05 Mar 2000) |
| silicone oils | Organic siloxanes which are polymerised to the oily stage. The oils have low surface tension and density less than 1. They are used in industrial applications and in the treatment of retinal detachment, complicated by proliferative vitreoretinopathy. (12 Dec 1998) |
| achromatic lens | A compound lens made of two or more lens's having different indices of refraction, so correlated as to minimise chromatic aberration. (05 Mar 2000) |
| acoustic lens | In ultrasonography, a lens used to focus or diverge a sound beam; may be simulated by electronic manipulation of signals. (05 Mar 2000) |
| anterior pole of lens | The central point on the anterior surface of the lens of the eye. Synonym: polus anterior lentis. (05 Mar 2000) |
| anterior surface of lens | The anterior surface of the lens of the eye. Synonym: facies anterior lentis. (05 Mar 2000) |
| aplanatic lens | A lens designed to correct spherical aberration and coma (q.v.). Synonym: periscopic meniscus. (05 Mar 2000) |
| apochromatic lens | A compound lens designed to correct both spherical and chromatic aberrations. (05 Mar 2000) |
| asphenc lens | <physics> A lens made aplanatic by grinding the outer zones to a greater radius than the inner zones. Aplanatic condensers can be made in this way. A simple aspheric lens is widely used as a lamp condenser because of its efficiency in converging light rays to one focal plane. (05 Aug 1998) |
| aspheric lens | A lens with a paraboloidal surface that eliminates spherical aberration. (05 Mar 2000) |
| astigmatic lens | A lens in which one of the surfaces is curved in one meridian and less curved in the opposite meridian; e.g., a teaspoon or a football. Synonym: astigmatic lens. (05 Mar 2000) |
| axis of lens | A line connecting the anterior and posterior poles of the lens of the eye. Synonym: axis lentis. (05 Mar 2000) |
| back lens | <physics> In any compound lens (a lens system composed of more than one lens element), the last lens through which the light passes is called the back lens. It may be a single simple lens, a doublet, or triplet. See: front lens (05 Aug 1998) |
