Special limits of human vision - How well do you see light changes?

An opportunity to take part in research on the limits of human vision.

  • Research Participant
  • Participate


The Institute of Neuroscience is looking at special limits of the human vision. Particularly in relation to changes in ambient light. The results will help inform strategies to improve specialised illuminations like the ones used in museums and medical surgeries.

This study is part of an EU cohort of international labs dedicated to “Dynamics in Vision and Touch – the look and feel of stuff” (, supported by the European Union’s Horizon 2020 research and innovation programme.


Volunteer Criteria

To take part you must satisfy the following inclusion criteria:

  • Aged over 18 years
  • Normal vision or corrected to normal (glasses, contacts, etc.)
  • No colour blindness or other colour vision deficiencies.
  • No epilepsy or any conditions sensitive to strong changing lights.
  • Generally healthy with no underlying medical conditions and no recent bouts of ill health

What will I be asked to do?

You will need to make 3 - 4 visits to the lab. In each visit, you will take part in computer tasks, which involve looking to changes in the ambient illumination and make decisions about them. We will also ask you some questions about your sleep habits. Each session will take about 1 to 1.5 hours depending of your response time and length of breaks.

When and where?

All testing will take place at the Institute of Neuroscience, Newcastle University. Full instructions will be given when you make your appointment.

Appointments will be arranged with each individual participant. Generally speaking, sessions will take place sometime between 7-9 AM and 7-9 PM, but out of hours arrangements can also be made upon request.

Will I get anything for taking part?

Participants will receive £45 in Amazon vouchers for their time.

    Perhaps someone could explain "Generally healthy with no underlying medical conditions and no recent bouts of ill health."

    It is a little confusing :(

    My availability is better after 10 a.m. I had intra-ocular artificial lens replacements in both eyes in 2011, after having worn spectacles for 60 years. Do I still qualify to take part?

    I would find this project very interesting and would enjoy taking part.
