Patents

As part of the innovation, we filed and received approval for patents for an “Apparatus and method for establishing and/or improving binocular vision. The patents cover the EU and USA. Our brain-eye coordination training uses our patents to improve the vision when using both eyes. And our patents cover an eye-motor movement that has individual impact on each eye, for all types of screens and images. The patents also protect individual manipulations of the image for an eye, related to changes in colour, toning, blurring and movements.

Collaborations

During the development, several studies have been done in collaboration with Karolinska Institutet in Stockholm, within the field of Neuroscience/Optomertry, Linné Universitet in Växjö, within the field of Pedagogy, and Högskolan i Gävle in Gävle within the field of Neurological measurements. We are continuing our collaboration with academia going forward.

Vergence problems, reading disabilities and dyslexia

Background
Vergence problems are common, with approximately 10% of the population being impacted. Some claim that more than 25% are affected, and that the increased use of mobile devices has a negative impact on specially children.

Vision and Reading
A few visual skills are required for reading. These are: accommodative, oculomotor, binocular, and processing. Vergence problems are linked to binocular vision.

Accommodation is the ability of the eye to change the focal length of the lens by changing the curvature of the eye lens. Accommodation allows the eye to automatically adjust focus from seeing things at a distance and “tune” it to seeing nearer objects. Disorders place a strain on the binocular system.

Oculomotor skills can be defined as the eye’s ability to locate and fixate on an object in the field of vision. This focus is the result of a smooth, coordinated movement of the eyes, to attend and follow objects and people. The oculomotor system must provide accurate, fast control for reading to allow the reader to maximally extract visual information from text. Small eye movements called saccades are incredibly fast. Most saccades move the eyes along the text in a forward fashion (left-to-right in English text for example), however, about 10-20% of saccades are in the backward direction (regression). Poor oculomotor control may lead to a substantially higher number of regressions.

Binocular vision is the ability to maintain visual focus on an object with both eyes, creating a single visual image. Lack of binocular vision is normal in infants. Adults without binocular vision experience distortions in depth perception and visual measurement of distance. Binocular disorders can often be more problematic in the middle and advanced stages of reading. Any condition that disrupts clear, single, comfortable vision has the potential to impact reading ability. Common binocular vision disorders may negatively impact reading ability and produce similar symptoms such as: blurred vision, double vision, headaches, eye ache, or eye strain, fatigue, or tired sensation.

Computerized vergence training

Manual vergence trainings have been in place since the 1950ies. These methods work but are not very practical due to the very high effort required in terms of motivation and supervision with daily trainings and weekly visits to a clinic during a period of six months.

RetCorr’s computerized training with a desktop computer and a 3D-screen and 3D-glasses improved both the efficiency and effectiveness compared to the manual methods. For full article press link. Our new training, imvi read, is delivered using a mobile app with VR-glasses. imvi read is based on the same patents as the RetCorr solution, with a preliminary study showing that imvi read is somewhat more effective than RetCorr. A comprehensive study is ongoing at Karolinska Institutet.

Neurological drain

Research done at Gävle Högskola, led by Professor Hans Richter, shows that the vergence system will be able to drain the frontal cortex for up to 90% of its energy by stimulating eye movements as little as 5-10 minutes. A minor vision-related vergence problem can thus drain the brain from the needed energy to perform other tasks, with a negative impact on tasks such as reading. For full article press link.

Reading

Professor Christer Jacobson has in his research concluded that for people with reading and writing disabilities or dyslexia, vision could have an impact. And that vergence training could have a positive effect on reading for people with vergence problems: For full article press link

In studies involving our solution, results show a positive development for reading speed and concentration skills among persons with reading and writing disabilities or dyslexia as well as ADD and ADHD.

Factors behind reading disabiliteis and dyslexia, adapted from Christer Jacobson

Our method has been used in several studies showing:

  • Its effectiveness and efficiency for improving eye-coordination, i.e., the vergence function.
  • Its results on improving reading speed and stamina
  • Its results on decreasing common symptoms like headaches, eye ache or strain, concentration issues, fatigue etc.

And doing so for both:

  • People with vergence problems
  • People with reading problems and dyslexia
  • But also, for people who do not have vergence problem, but still can further improve their eye-coordination
