VISUAL ACUITY CHECK

Visual Acuity check is the test initiated to examine patients' potential eyesight problems. After detection, it is then rectified under the guidance of a professional (ophthalmologist) with appropriate solutions. This test usually includes expensive instruments which make the setup bulky and immobile. Due to the limited resources and high cost, people residing in remote areas do not prefer to undergo this test which makes them ignorant concerning their visual health. So, to turn their attention towards visual health and help them avail this test, we are trying to propose a set-up namely Visual Acuity Check with minimum instruments. The key components of this setup are a standard Snellen Chart, a system that uses a Speech-to-text converter, and a node MCU for remote automation. This system includes pre-defined standard formulae and conversions for diopter calculations. This test does not necessarily require any professional handling. Thus, this movable setup will offer high efficiency at a very low cost. Key Words: Snellen chart, Node MCU Module, speech to text converter system.
