Portable Ophthalmic Refractometer to Witness High Demand Due to Its High Accuracy and Emergence of Covid-19

 

Portable Ophthalmic Refractometer

An ophthalmic refractometer is a device used for measuring the refractive error of a patient's vision. This is done by passing an invisible beam of light through a very tiny sample of the patient's eye and capturing the results. The results are shown on a computer screen, and this device is widely used in clinical and lab tests.

Uses

Ophthalmicrefractometer can be used in diagnosis of myopia (nearsightedness), hyperopia (farsightedness), and astigmatism. In Germany, the prevalence of myopia is 13.3% for the age group 3 to 17 years.

Automated Refractometry

Automated ophthalmic refractometers save time, reduces costs, and improves operational safety. These computer-controlled machines provide an objective measurement of a person's refractive error and prescription for glasses or contact lenses. The main components of these automated systems include instrumentation and computer software. The instrumentation consists of both coupler and lens forms that are using to get clear images of the different parts of the eye. Lenses are used to focus light into a scanner that takes a detailed photograph of the eye. The camera, scanner and instrumentation then allow the physician to create an image of the patient's eye and get important details about the health of the retina, lens and other optical components.

Portable Ophthalmic Refractometer

Smartphone-based refractometry is an emerging trend, which allows to conduct refractions and collect the basic measurements required for glasses anywhere. A portable kit may include, auto-refractors, auto-lensometer/focimeter, phoropter/trial lens kit, and a smartphone. A portable refractometer is capable of simultaneously measuring the refraction of both eyes (binocular) at one meter distance. With the emergence of Covid-19, the demand for such refractometers is expected to increase as they provide measurements at one meter distance without any contact.
