Abstract/Introduction

Purpose

This study evaluated the effects of short term and extended viewing of virtual imagery using the Binocular Viewer (new generation bi-ocular viewer) on the visual system of children, and compared these effects with that of viewing a high definition television (HDTV) display.

 

Methods

Sixty children aged 5 to 16 years viewed 30 min of virtual imagery using the Binocular Viewer and a HDTV display on two occasions. Sixteen subjects, aged 13 to 16 years, completed a third session of extended viewing (80 min) with the Binocular Viewer. Oculomotor function and symptoms were assessed previewing, immediately postviewing, and 10 min postviewing.


Conclusion/Results

Results

Thirty minutes of Binocular Viewer use resulted in symptom increases (p < 0.05) immediately postviewing (“feeling tired,” “feeling sleepy,” “difficulty concentrating,” and “sore/aching eyes”) however most symptoms had dissipated by 10-min postviewing. There were no significant symptom differences between viewing with the Binocular Viewer and the HDTV display at either time point. An increase in symptoms (p < 0.05) immediately postviewing was recorded after 80 min of Binocular Viewer use (“feeling tired,” “feeling bored,” “feeling sleepy,” and “tired eyes”), however only “feeling tired” and “feeling bored” remained significantly increased (p < 0.05) 10-min postviewing. Near unaided visual acuity demonstrated a significant and consistent reduction immediately (p < 0.01) and at 10 min (p < 0.05) following 30 min of Binocular Viewer use and immediately following 80 min of use (p < 0.01). Near unaided VA was also significantly reduced (p < 0.01) immediately after 30 min of HDTV display use.

 

Conclusions

Virtual imagery viewing with the Binocular Viewer in children aged 5 to 16 years had few additional adverse effects when compared to viewing a more conventional HDTV display. The Binocular Viewer was comfortable to wear for up to 80 min of viewing. The consistent reduction in near vision for both viewing durations with the Binocular Viewer requires further investigation.


Testimonials


  • Such a nice optician. My grandson is only 4 and needs glasses. We were so sad, but he explained the issues, and we will follow up as he suggested.

  • I had such a good experience with the clinic. Very friendly staff and doctor, did not have to wait for long to be called, and was treated respectfully. Thanks, American Family.

  • Dr. Zurcher has gone above and beyond what any other eye doctor has ever done to figure out what is going on with my eyes. Very happy with American Family Vision.


    Christine R.

  • Family Vision Clinic changed our lives! My daughter was frequently car sick, and she was getting headaches every day, often painful enough that they brought her to tears. We saw a string of doctors and therapists, but we made no progress. Finally, we found Dr. Levi Zurcher and his eye therapist Rain. After ten weeks of eye therapy my daughter no longer gets headaches, and she no longer gets car sick. Daily tears are a thing of the past. I really can’t say enough about this clinic. It was fascinating to watch Dr. Zurcher work. For the first time, someone who knew what they were doing was intently studying my daughter, really trying to figure out all of her eye issues, and his therapist Rain is one of the most patient and lovely people that I’ve ever had the good fortune to meet. We’re finished with eye therapy—yay!—and I have switched to American Family Vision Clinic for all of my family’s other eye health needs.

  • Very professional, yet kind and helpful. They do what they can to make the appointment comfortable. I was running a bit late, I made sure ti call. They were able to switch me with a patient who was already there, they treated me with respect, and helped my son have confidence by getting him the eye care he needed that day. Thank you so much! Would recommend to anyone. It's a blessing that they care enough to work with people who have all different types of insurance from work to state coverage.
