Digital Life Line, a privately held associate company of catalist-listed Disa (Digital Safety) 532 has signed a tri-party licensing agreement with the National University Hospital (NUH) and National University of Singapore (NUS) on June 19 to commercialise the Automated Visual Acuity Test device (AVAT), which measures eyes' ability to distinguish shapes at a distance and Smart, User-friendly Portable Reliable Automated perimetry device (SUPRA), which tests visual fields.
The technology was developed at a unit of NUS' Medicine faculty, and refined after testing in the clinical setting at NUH.
These are portable devices that are able to "decentralise" the current care model of conducting eye screening and monitoring of eye diseases.
"Community deployment of such devices will allow people to get eye screening more regularly and conveniently in primary care settings such as polyclinics or optical shops," the Disa announcement says.
"A minimum of 6 meters between the patient and the Snellen chart is required to conduct the visual acuity testing, where not all polyclinic or optometrist have the privilege of space to conduct the eye screening," Disa says.
AVAT relies on optical components that are able to shorten the distance between the individual and the display, while ensuring comparable results of that with a Snellen chart which has a minimum requirement of distance.

The AVAT device can fit on a desk that is about half the size of an office table and also incorporates an interactive interface that displays test characters after analyzing user input.
SUPRA is an AI-based portable visual field-testing device that allows diagnosis of perimetric glaucoma, retinal or neuro-ophthalmological diseases.
Disa closed at 0.3 cents on June 20.
