| multifocal lens | A lens with segments providing two or more powers; commonly, a trifocal lens. (05 Mar 2000) |
| plus lens | A converging lens. Synonym: plus lens. (05 Mar 2000) |
| contact lens | A lens that fits over the cornea and sclera or cornea only; used to correct refractive errors. (05 Mar 2000) |
| contact lens solutions | Sterile solutions used to clean and disinfect contact lenses. (12 Dec 1998) |
| convex lens | A converging lens. Synonym: plus lens. (05 Mar 2000) |
| convexoconcave lens | A minus power lens having one surface convex and the opposite surface concave, with the latter having the greater curvature. (05 Mar 2000) |
| convexoconvex lens | A lens with both surfaces convex. Synonym: convexoconvex lens, double convex lens. (05 Mar 2000) |
| corneal lens | Contact lens of plastic without scleral portions. (05 Mar 2000) |
| cortex of lens | The softer, more superficial part of the lens of the eye that encloses the central part or nucleus; its refractive power is less than that of the nucleus. Synonym: cortex lentis. (05 Mar 2000) |
| positive lens | <physics> Any lens with a positive focal length. Such lenses are thicker in the centre than around the circumference. There are three types of positive lenses, double convex or biconvex, planoconvex, converging concavoconvex or converging meniscus. (05 Aug 1998) |
| posterior pole of lens | The central point on the posterior surface of the lens. Synonym: polus posterior lentis. (05 Mar 2000) |
| posterior surface of lens | The posterior surface of the lens of the eye. Synonym: facies posterior lentis. (05 Mar 2000) |
| crystalline lens | <physics> A transparent optical element, so constructed that it serves to change the degree of convergence or divergence of the transmitted rays. (05 Aug 1998) |
| cylindrical 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) |
