3rd International Symposium on Visual Physiology, Environment & Perception in Tallinn, Estonia

On behalf of the organising committee,

we are pleased to welcome you to the 3rd International Symposium on visual physiology, environment, and perception.

The Symposium is a collaborative project of scientists from three Baltic countries – Latvia, Lithuania, and Estonia, to make vision science more recognisable in our region. 

Hosting institutions: Tallinn University & Tallinn Health Care College 

Venue: Tallinn University on 13-14th November 2020 

Extra treat: workshops for optometrists at Tallinn Health Care College on 12th November 2020 


We welcome participants from any country involved in various fields of vision science. The main aim of the Symposium is to promote cooperation and communication between eye care professionals and researchers from various fields of vision science. 

  • Clinical studies (clinical studies in optometry – clinical cases, diagnostics, and treatment); 

  • Visual physiology (accommodation, binocular and monocular eye movements, pupil physiology); 

  • Environment (lighting, visual fatigue, technology of visual stimuli); 

  • Visual perception (visual attention, colour perception, spatial vision). 

We look forward to welcome you at VisPEP2020 in Tallinn! 


Additional information will be added shortly!





2nd International Symposium un Visual Physiology, Environment, and Perception successfully organized in Vilnius

In 2018, the symposium was held in Vilnius, Lithuania. It was jointly organized by the Lithuanian Neuroscience Association, the Department of Optometry and Vision Science (University of Latvia), as well as the University of Tartu (Estonia), bringing together the 10th Conference of Lithuanian Neuroscience Association and the 2nd International Symposium on Visual Physiology, Environment, and Perception (the conference webpage: http://www.neuromokslai.lt/en/conferences/lna-conference-2018/).

176 researchers and students took part in the event representing 15 countries (Lithuania, Latvia, Estonia, Finland, Poland, Russia, Hungary, Germany, Switzerland, France, Israel, United Kingdom, Saudi Arabia, USA and Japan). In total, there were 23 oral reports and 50 poster presentations at the conference. The authors of three best poster presentations received the awards.

In 2020, the symposium will be held in Tallinn (Estonia).

Early registration – 1 September 2016

The program of the symposium is now being prepared. We have participants from Latvia, Lithuania, Germany, Switzerland, Russia, Poland, Brazil, UK, USA. There will be oral presentations and posters about illusions, comfortable brightness, colour vision, fixation disparity, binocular functions, amblyopia, myopia, orthokeratology, keratoconus, visual grouping, mental rotation, coherent motion etc.

Our main sponsor HOYA will present Hoya EyeGenius, a completely new system for full vision examination with a unique method for measuring and correcting fixation disparity. It is the fastest solution on the market today, delivering the ideal prismatic prescription in under ten minutes. Essential background information about the new system will be presented to explain its functioning.



The early registration is still available up to 1 September 2016.

For those having no possibility to attend the symposium in Riga, we offer possibility to follow the lectures and presentations via videoconference.

We are still working to ensure that videoconference participants can take active part in discussions.

Hope you will enjoy the symposium.
