Focometer

Focometer

Fokometer minangka instrumen sing ngukur kesalahan-kesalahan refractive lan dimaksudake kanggo nyedhiyakake resep-resep kacamata spherical pedesaan utawa ekonomi sing mbebayani tanpa perlu protokol rumit, peralatan larang, utawa listrik. Fokometer punika monocular lan tangan-tangan, lan biasane digunakake ing cahya alami. Pasien muterake ikatan ing fokometer nganti fokus paling apik. Daya refraktif individu kasebut banjur maca ukuran skala dioptre. Fokometer iki dikembangake dening Drs. Ian Berger lan Larry Spitzberg ing Universitas Houston Optometri ing Houston, Texas, kanggo nyedhiyakake sarana sederhana, murah kanggo ngukur kesalahan bias ing sesanti manungsa. Instrumen portabel, tangan-tangan banget cocok digunaake ing wilayah sing adoh lan kurang. Focometers ngukur kasalahan refractive spherical. Astigmatisme uga bisa diukur nganggo "target jam" karo piranti kasebut. Nanging, panaliten ngerteni yen fokometer kurang efektif kanggo ngenali astigmatisme tinimbang autorefractor, lan akurasi sumbu sawijining diwatesi dadi 15 °.

A focometer is an instrument that measures refractive errors and is intended to provide rural or economically disadvantaged populations spherical eyeglass prescriptions without the need for complicated protocols, expensive equipment, or electricity. The focometer is monocular and hand-held, and is normally used in natural lighting. Patients rotate a collar on the focometer until the best focus is achieved. The individual's refractive power is then read off a linear dioptre scale. The focometer was developed by Drs. Ian Berger and Larry Spitzberg at the University of Houston College of Optometry in Houston, Texas, to provide a simple, inexpensive means for measuring refractive error in human vision. The portable, hand-held instrument is highly appropriate for use in remote and poor areas. Focometers measure spherical refractive errors. Astigmatism can also be measured using a "clock target" with the device. A study has found, however, that the focometer is less effective for identifying astigmatism than an autorefractor, and that its axis accuracy is limited to 15°.
