Mobile Phones Causing Presbyopia At An Early Age, say Doctors

The excessive use of mobile phones and other electronic gadgets is causing presbyopia at an early stage. The eye disorder typically occurs in middle and old age and is caused by loss of elasticity of the lens of the eye.

According to doctors, over 65 per cent of the people suffering from presbyopia, or long-sightedness, in their early 30s in India, were found to be heavy users of electronic gadgets, including tablets and laptops. 

“Presbyopia or loss of accommodating power of the lens, which mostly happened around the age of 40, has started occurring quite early among the people. Excess use of mobile phones causing it early by making the eye lens harder and making it lose elasticity. The result is a gradual worsening of the ability to focus on objects up close,” said Mahipal Sachdev, Chairman of Centre for Sight (CFS).

According to World Health Organisation, more than a billion people in the world were presbyopic as of 2005, while the number has doubled in 2015.

Stating that presbyopia is even seen among people in their early 30s, Sachdev said: “Surveys have proved that symptoms of presbyopia such as blurred vision, eye strain or headaches are more often seen among the youngsters too who use electronic gadgets such as mobiles for long hours.”

Presbyopia, an age-related eyesight problem, stems from a gradual thickening and loss of flexibility of the natural lens inside your eye. The problem is now occurring at an early stage due to use of mobile phones and other electronic gadgets in excess.

These age-related changes occur within the proteins in the lens, making the lens harder and less elastic over time. Age-related changes also take place in the muscle fibres surrounding the lens. With less elasticity, the eye has a harder time focusing up close.
Ritika Sachdev, a Delhi-based ophthalmic surgeon, said: “One cannot escape presbyopia, even if they have never had a vision problem before. However, the occurrence of presbyopia at an early stage can be prevented by avoiding the long-hour use of mobile phones and tablets.” 

“Presbyopia also cannot be prevented just by diet and exercise as they have no effect. Those who use near vision daily in their activities will notice and complain about it sooner. Which is why these days, with greater use of mobile phones and tablets, people need corrective glasses sooner, sometimes even at the age of 30-32 years.”

  Excessive use of electronic gadgets has led to a rise in cases of hunched backs among youngsters, health experts have said.
 
They said the problem initially begins as a mild case of bad posture when the children are comparatively young, but slowly begins to develop into hunched back and shoulders. 
 
"It all starts with a bad posture due to spending more time on small digital screens. The more they get addicted to the gadgets the more the children are comfortable in the bad position," said Dr Arvind G. Kulkarni, head of Spine Scoliosis and Disc Replacement Centre at the Bombay Hospital in Mumbai.
 
Hunched back is a medical condition of exaggerated curving of the upper back. Typically, head and shoulders shift forward, the chest curls inwards and the spine crunches from a healthy 'S' curve to a less healthy 'C' position as the pelvis tilts forward.
 
"Though associated with old age, hunchback is a condition commonly seen among the youngsters these days, especially those between 9-18 years old. The main cause is weak abdominal muscles from years of sitting in a hunched position. This places uneven pressure on the discs, the cushioning pads between the bones of the lower back, causing them to become compressed and painful," said Kulkarni.
 
Hyperkyphosis or excessive curvature of thoracic spine is more common among hunchbacks if not treated on time.
 
"Many people with hyperkyphosis suffer from shortness of breath and other breathing issues. It may also cause anxiety and depression, increased risk of cardiovascular or lung disease and Type 2 diabetes," said Kulkarni.
 
Talking about the treatment, orthopaedician Ronit Singh of Safdarjung hospital said: "With children and youth, it's important that they learn the correct way to sit, especially when using computers, mobile phones and tablets."
 
"For the youth and the elderly, exercises like stretching etc often help improve the spine flexibility. Youngsters can emphasise on strengthening abdominal muscles as it helps improve posture. Practicing yoga is considered beneficial for good body posture. Yoga also helps in improving balance; strengthening the core muscles and helping you maintain a proper body alignment," he said.
 
He said that surgical procedures are recommended and done only if the spine curvature is exaggerated and if it is pinching the spinal cord or the nerve roots. 
 
"Surgery helps in reducing hunchback curvature. The most common procedure is spinal fusion where two or more affected vertebrae are permanently connected. Understanding the importance of good posture at a very early age is essential to maintain a healthy mind and body," he said.
