Smartphones Cause Shortsightedness*
If you don’t use it you lose it!
The eyes have muscles which have been designed to be used, something that has become less and less with the advent of the computer, and smear and smear screens. What happens when we use a screen is that eyes are locked into one position – straight ahead for long periods of time without looking left or right or into the distance.
The Daily Mail reports on an upshot in short sightedness among young people since 1997 according to leading laser eye surgeon David Allamby, founder of Focus Clinics, says there has been a 35% increase in cases of advanced myopia (short sightedness) since the launch of smartphones in 1997.
Dubbed ‘screen sightedness’ by Allamby Britons spend an average of two hours a day on smartphones in addition to computers and watching television – the result permanent damage to their sight. When we read a newspaper/book according to research it is held at 40cm away from the eyes. A smartphone is held at 30 cm – 18cm away from the face.
Myopia used to stop developing in people’s early 20s but now it is now seen progressing throughout the 20s, 30s, and even 40s. Allamby believes today’s children are most at risk of myopia – with children as young as seven being given smartphones.
Researchers at the University of California found that the problem is the demand on the eyes to focus on the screen and simultaneously adjust to the distance of the content.
The phenomenon is known as ‘vergence-accommodation’ and experiments found people suffered discomfort when content from mobile phones appeared in front of the screen rather than behind it.
