The Folding Phoropter is aiming to rural low-income communities.The phoropter appears like a telescope and is measured using the most common refractive error ranges. The test on the device was carried on 100 people and it showed a strong correlation between its reading and those taken with a clinical setting with the usual ophthalmologist tools. The device is easy to assemble and anyone can build their own following the instructions.
USAGE OF FOLDABLE PHOROPTER
The lenses require being located in their assigned positions and folded along the lines. The two parts line up inside one another, resembling a telescope. The patient needs to look through the device from the fixed distance and move the outer chamber inwards until the image just comes into focus.
