Christine Svensson, Helle Vedø og Michala Mathiesen started the company Ballast CPH in 2016 after finishing their master's degree in Sustainable Design from AAU CPH.

Their shared thesis project became a stepping stone towards creating their own business. With the goal of empowering people with low vision and improve social equality, they developed a pair of vision simulation goggles called Perspectacles. Later on the learning board game Indsigt (in English: Insight) has been developed and in he beginning of 2018 an Augmented-Reality APP will be a new tool.

The three female entrepreneurs use their design and engineering skills from their studies on a daily basis, and through Ballast CPH they offer consultancy and workshop facilitation within user involvement and accessibility optimization.

Our vision
Our vision is to remove barriers and ensure that people with low vision is included equally to people with high vision at work and in society. Using enlightenment and education with sight simulations we ensure a better understanding about people with impaired vision. .

Perspectacles Simulation Goggles


Perspectacles simulation goggles make it possible to experience different kinds of low vision with your own eyes. As a sighted person it can be hard to understand what it really means to be partially sighted, e.g. having tunnel vision, blurred vision or spotted vision. Perspectacles help create empathy and a bodily understanding of partial sightedness. The simulation goggles add valuable insight in the daily challenges that partially sighted people meet.

The simulation goggles come with an adhesive vision filter to simulate a particular condition. The original vision filter can be replaced with other filters to simulate different conditions. These filters can be combined as needed for personalization of the simulation experience. Sheets of additional vision filters can be bought separately.

Perspectacles are easily adjusted to different head sizes, and the foam lining makes sure that the simulation experience is comfortable. The simulation goggles are developed in close collaboration with The Institute of the Blind and Partially Sighted (IBOS) in Denmark and with partially sighted users and their relatives.


Indsigt (in English: Insight) is a simulation game, which guides the players through the day of one of two main characters Ingrid or Osman. While wearing simulation goggles that matches the main character's vision they complete different everyday tasks. Indsigt adds valuable reflections about the daily challenges that the main character meets and leads to a collection of concrete solutions that can ensure better accessibility for those with low vision.

The game is currently only in Danish but will be translated.

Three men wearing Augmented Reality goggles


Ballast CPH is currently working on an Augmented Reality-app that will digitize our analogue Perspectacles. In the beginning the app will have three kinds of filters: cataracts, glaukoma and age-related macular degeneration. These three kinds of eye sicknesses have been chosen because they usually occur in older people. The plan is to have more filters added.

The first edition of the app is expected to be finished in the beginning of next year.
