A computerised Test Chart to meet your exact requirements

In the mid-90s, a team from City University London led by Professor David Thomson, set about developing the software to exploit new developments in computer and display technology to provide eye care professionals with a powerful new set of tools for vision assessment in the consulting room. Test Chart 2000 was launched in January 2000 and was the first Windows-based computerised test chart in the world.

Since then, Thomson Test Chars have been installed in over 8000 consulting rooms including optometric practices, many major hospital eye departments, all the University Optometry Departments in the UK and many overseas, Diabetic Screening Units, Occupational Health Departments and Research Laboratories.

Today we offer a range of software options to meet your exact requirements. You can run this software on your own PC or we can provide a range of complete solutions which you can use "out of the box".

Whether you require a single Test Chart for your practice of a whole hospital eye department equipped, we have a solution for you.

Remote acuity testing using Thomson Test Charts

Outline instructions:

Create a meeting and send the patient a meeting invitation link.
Add the patient to the meeting when they log in. You can then welcome them and explain the procedure by video link.
Run the Thomson Test Chart software on your computer and select Share screen in the video-conferencing app
Select Options ... Screen calibration within the Test Chart software. This will display a large letter E on the patient's screen which they should measure on their screen using a ruler. You then enter this value into the Test Chart software along with the longest viewing distance that they can achieve from their computer (e.g. 250 cm). The letter size will then be correctly calibrated for the patient's screen size and viewing distance.
The patient then stands (or sits) at the required distance from their screen while you display an appropriate test chart. The patient can be given appropriate instructions and encouragement via the videolink while you can monitor that they are following those instructions.

Trials have shown that the accuracy and test/retest repeatability of this approach is similar to that for measurements taken in the clinic.

Current guidelines on Social Distancing have made it difficult (or impossible) for patients to attend a clinic to have their visual acuity checked.

The good news is that the Thomson Test Chart may be used in association with video-conferencing software (e.g. Zoom or Teams) to assess the vision of patients in their homes or other remote locations.
