BVD: The Clinical Frontier of Vitamin A Diagnostics

Medical Innovation

Bright Vision Detector

Thousands suffer from Vitamin A deficiency leading to blindness and related complications.

But here’s the opportunity:
You can detect it early AND build a profitable business.

With BVD, you can:

Problem

Vitamin A deficiency has a high prevalence in India (~15% in kids, ~7% in adults).

The deficiency leads to preventable blindness, lower immunity, reduce eyesight, complications during pregnancy, high maternal and child mortality, various infections affecting skin, respiratory, urinary tract, genital organs, gastrointestinal tract, eyes etc. Vitamin A deficiency also leads to more road traffic accidents as well as industrial accidents etc. Growth retardation, infertility, reduce productivity and circulatory problems are also added problems due to Vitamin A deficiency

Existing test methods for determining the deficiency of Vitamin A require blood samples and are resource intensive (cost, time, facility etc.). Less than 1 % of laboratories are having facility for Vit A level and that will cost 4000 to 5000 rupees.

The lack of a quick, efficient, and inexpensive testing instrument for the Vitamin A deficiency may lead to lack of treatment as well as prevention.

There is no device in existence that can test for night blindness. Night blindness can occur due to several causes and mostly it requires expert opinion of ophthalmologist. Hence early detection of night blindness can be helpful to early detection of its underlying causes. This will prevent complications due to cataract, glaucoma, diabetes etc.

Solution

Night blindness and dark adaptation time are massively impacted by the concentration of Vitamin A in the body.

A digital instrument prototype has been created to evaluate the presence and extent of night blindness as well as dark adaptation time.

With a specific procedure being followed, this instrument can be used to predict the existence of the Vitamin A deficiency. This can be confirmed by giving dose of Vitamin A and retest after 1 week to see the reduction of light required to identify the object.

This instrument enables the formation of a solution which is portable, fast, cost effective, reliable, and can be used for a diverse set of applications.

Key Features

Non-Invasive Testing

Eliminates the need for blood samples, making the assessment process more comfortable for individuals.

Immediate Results

Provides quick evaluations, facilitating prompt intervention if necessary.

Cost-effective

Reduces expenses associated with traditional blood tests and related medical procedures.

Early Detection

Enables timely identification of Vitamin A deficiency, helping to prevent associated health issues such as night blindness and weakened immune function.

Ideal For

Hospitals

NGOs

Schools & Colleges

Private Clinics

How It Works

The Bright Vision Detector uses cutting-edge technology to assess the eye’s ability to detect objects in low-light conditions. This is based on the principle that the eye’s sensitivity to light is directly related to the level of Vitamin A in the body. When Vitamin A levels are adequate, the eye can detect objects in low light conditions. Conversely, when Vitamin A levels are deficient, the eye requires more light to detect objects.
