1. | A lens' focal length can be altered by: | ||
|
|||
|
|||
|
|||
|
|||
Changing the curvature of one surface. A lens with a higher angle of curvature will have a shorter focal length because the light waves are refracted at a greater angle with respect to the optical axis of the lens. As the refractive index increases or becomes more curved, the focal length of the lens decreases. Coating the surface of the lens will only change the properties of the surface not the focal length and changing the diameter while keeping the curvature of the surfaces of the lens the same, does not impact the angle of curvature or how light waves are refracted.

Minus lenses correct for near-sightedness or myopia which means a person can see objects close but cannot see far away. Lenses used to correct this are flatter on the front surface and more curved on the backside making the thinnest point in the center of the lens. A lens which has two spherical curved surfaces, concave on one side and convex on the other side is called a meniscus lens. When both surfaces of the lens are concave, therefore having the same focal length, it is called an equiconcave lens. Flat concave lenses have a flat surface on one side and a spherical surface on the other. Equiconvex, flat convex and meniscus are types of plus lenses. A meniscus lens can be either a plus or minus lens however, concave refers to minus lenses while, convex refers to plus lenses.

Domain IV - Instrumentation |
|
||
18. | Which instrument measures vertex distance? | ||
|
|||
|
|||
|
|||
|
|||
Distometer. Vertex distance is the distance between the front surface of the cornea and the backside of a corrective lens mounted in a frame to be worn by the patient. Measuring the vertex distance with a distometer for prescriptions greater than 4 diopters ensures the accuracy of the necessary power. When plus lenses are moved toward the eye, perceived power is lost; when moved away from the eye, perceived power is gained. For minus lenses, it is the opposite: when lenses move toward the eye, perceived power is gained and when they move away from the eye, perceived power is lost. A lensometer is an instrument used in dispensaries to determine the diopter powers of a lens. A vertometer also measures the diopter power of a lens but is more precise and is used in laboratories to locate and mark the optical center of a lens for edging and mounting. A polariscope is used during the lens inspection process to detect stresses or defects in different types of lens materials.
