Expert Opinion

"At the moment, those undergoing the treatment are between 16 and 53. On average, after only 10 sessions, not only is there great improvement in vision but it is also maintained for at least two years."
Prof Donald Tan, Director Singapore Eye Research Institute and Deputy Director, Singapore National Eye Centre
"This treatment helps the brain to better understand the images the eyes are sending it, rather than altering the images the eyes receive by using corrective lenses or surgically altering the eye itself."
Dr Chan Wing Kwong, Senior Consultant and Head of Refractive Surgery Centre, Singapore National Eye Centre
"For example, select an item in your house that you cannot see clearly. After that, every five sessions, take a look at the object again and you will notice that your vision has become sharper. These are testimonials from patients who have experienced this."
Prof Donald Tan, Director Singapore Eye Research Institute and Deputy Director, Singapore National Eye Centre
"Vision is dependent on two things, how your eye receives the image and how your brain interprets the image. NeuroVision helps the brain to interpret sharper images."
Dr Chan Wing Kwong, Senior Consultant and Head of Refractive Surgery Centre, Singapore National Eye Centre
"Naturally we were quite skeptical about the whole thing, because traditionally, ophthalmologists thought that apart from glasses and surgery, other methods wouldn't work for myopia. But we tried it out, and it did work."
Dr Chan Wing Kwong, Senior Consultant and Head of Refractive Surgery Centre, Singapore National Eye Centre
