AVAT is an self-automated visual acuity testing device that addresses the needs across public hospitals for fast and accurate screening measurements with smaller space occupancy.

AVAT (Automated Visual Acuity Testing) aims to decentralize eye screening and disease monitoring, meeting the rising demand for accessible care. By automating visual acuity tests, AVAT efficiently scales up testing, minimizes costs, and optimizes manpower resources. The device addresses current challenges by providing a streamlined, cost-effective, and accessible solution for widespread visual acuity testing. 


Increasing Demand for Vision Screening Market

According to PharmiWeb.com, the vision screening market is anticipated to exceed US$815.2 million by 20291.

Population growth, digital eye strain, rising prevalence of diabetes, and ageing are expected to increase the risk that more people acquire vision impairment, highlighting the urgent need for early screening to slow down vision loss and blindness


Singapore – Approximate number of people aged above 60 who have visual impairment. This number is expected to double by 2030.

2.2 billion

Global – Approximate number of people who have vision impairment, with at least 1 billion (50%) in which vision impairment could have been prevented with early detection. This is estimated to cost the global economy over US$3 trillion every year in lost productivity and health and social care2.

Existing Infrastructure Cannot Cope with Increased Demand

Problem: Current vision screening devices are costly, require large spaces for use, and need to be supervised by trained staff, which limits testing productivity and creates long wait-times. With worsening manpower shortages, existing infrastructure does not have a saleable approach to meet the increased demand for vision testing.


Screening equipment is bulky and expensive
→ costly to expand vision testing to more sites

Visual acuity test requires space
→ limits testing output in small clinic space

Manual vision screening
→ more manpower is needed to support greater demand for tests

Deployment Strategy



  • DLL vision screening devices are accurate and complement existing vision screening workflow by:
    • freeing up space, manpower resources
    • allowing self-administered testing with no supervision
    • require small footprint
  • Ideal for deployment in community for early detection and regular monitoring to prevent irreversible vision loss.
  • Demonstrates high levels of satisfaction and useability.
