Visual Acuity Test Device for Eye Specialist Doctors

Overview

Headless Technologies Limited designed and manufactured 1,000+ digital visual acuity tester devices for eye specialist doctors across Bangladesh. These devices are produced exclusively for Lasso Enterprise, who market and distribute them nationwide. The solution modernizes traditional eye charts by offering reliable, standardized, and clinic-ready digital vision testing.

Challenge

Eye clinics in Bangladesh often rely on printed Snellen charts that degrade over time, lack flexibility, and are difficult to standardize across rooms and distances. Lasso Enterprise required a cost-effective, durable, and scalable digital alternative that could be deployed in diverse clinical environments—from small chambers to large hospitals.

Solution

Headless Technologies engineered a custom visual acuity testing system available in 19-inch, 20-inch, and 32-inch form factors, optimized for different room sizes and viewing distances.
Key features include:

• Multiple test modes (Snellen-style E chart, color vision test, Bangla characters, anatomical visuals)

• Remote-controlled operation for hygienic, hands-free use

• High-contrast, medically appropriate display calibration

• Robust enclosure suitable for long clinic hours

The system was designed with simplicity in mind, allowing doctors and assistants to operate it with minimal training.

Manufacturing & Scale

We handled end-to-end manufacturing, including hardware sourcing, firmware configuration, quality control, and batch production. Over 1,000 units were delivered with consistent performance, enabling Lasso Enterprise to scale sales rapidly without technical bottlenecks.

Impact

• Adopted by hundreds of eye specialists across Bangladesh

• Improved examination efficiency and patient experience

• Reduced long-term maintenance costs compared to printed charts

• Strengthened Lasso Enterprise’s product portfolio with a locally manufactured medical device

Outcome

This project demonstrates Headless Technologies Limited’s capability to design, manufacture, and scale medical-grade electronic devices tailored for emerging markets—combining affordability, reliability, and real-world usability.
