Digital device guidelines

Digital devices 2015

Binocular problems have occurred in the population before digital devices but the addition of these has increased the symptomatic reporting of headaches, light sensitivity, soreness around eyes, blur at all distances and double vision.

 

Cases presenting at Lincoln Eye Optometrists were infrequent in the past have become prevalent in recent years.

Findings

Frequently, patients have no refractive error or no change in refractive error but are very uncomfortable because of their symptoms.

Typically, the binocular vision performance is impaired.

 

Solutions

The vision exam results provide the option of glasses for focus and binocular alignment of the eyes; coloured lenses; binocular vision therapy.

 

Additionally, I require each patient to consider the guidelines below as an essential part of reducing or resolving the symptoms presented.

 

Comment 
The origins of the binocular vision problem may be the accrued time viewing and interacting with the mini-ipad ( or small digital screens) at school, home and throughout the year.  This includes viewing images on instagram and not limited to reading print.

Guidelines that I am recommending to patients of all ages are:

 

  1. Increase the size of all tool bars
  2. Enlarge the size of all active screen text fonts
  3. Enlarge images and articles whenever possible
  4. Consider back colour and text font style
  5. Be able to alter the brightness setting to be the minimum needed and consider this throughout the day and evening
  6. Holding distance should be no closer than the length of the forearm from nose to surface.

 

  1. View images and content on screens at least full ipad or full tablet size but with a preference for the lap top and PC screens for reading articles or completing online activities.

  2. View with good posture seated or standing (not lying on the stomach with the view in upgaze, not with the screen on the chest, nor lying sideways).

 

  1. Ensure a side lamp, at least, is on at all times when viewing any digital screen, including phone, ipod, pads, laptops, PCs, and TVs.

 

  1. Regular breaks are required considering the age and tiredness of a child.

Data entry studies for adults recommended 50minutes viewing time, then 10 minute break in the workplace for an 8 hour day.
Childrens visual development is occurring throughout childhood and is not performing as adult visual systems do until growth has settled (growth settling for most boys over age 20 yrs and late teens for girls).

 

The above recommendations are provided to assist patients who are seen at our practice. The need to have children at school able to learn and for adults to be at work safely, with clear single sight, has caused me to provide the best advice I can from the cases that I have seen in the last two years. I am not aware of any scientific studies that support all of the above at present.
