A simple subjective telescopic refraction system has been custom designed and built. The telescopic refraction accommodates a range of refractive errors from +0.62D to -9.37D, which is skewed towards the various amounts of myopia due to the prevalence of myopia in Asia. This range can be modified in order to capture the specific distribution of refractive errors of a population.<\/span>

In using the calibrated 2.4X telescope for subjective refraction, the length of the telescope and the position of the stenopaic slit are adjusted by the examiner while the subject focuses a target on a distant visual acuity chart. The slit\u2019s size and position can be changed easily thus enabling the examiner to obtain the refractive error findings easily by changing the length of the telescope. Refractive error can be measured in a few minutes. Since it is subjectively determined, it is generally more reliable than those findings obtained with objective refraction techniques.\u00a0<\/span>

Special Features and Advantages<\/span><\/strong><\/p>\n

\u2022 The device is developed based on advanced \u00a0 \u00a0designation which is small in size and cheaper.<\/span>
\u2022 With short period of training it can be easily \u00a0 \u00a0used.\u00a0<\/span>
\u2022 Efficient, reliable and accurate assessment of refractive error.<\/span>

Applications<\/span><\/strong><\/p>\n

\u2022 The device can be used as a portable subjective refraction system determining the refractive errors of patients who cannot access the services of an optometrist or ophthalmologist.<\/span>
\u2022 The device can be used as a pair of full field binoculars without the stenopaic slits.<\/span>
\u2022 The device can be used as a low vision aid for the partially sighted.<\/span><\/p>\n
