Smart phones overuse may damage eyes
A survey of 2,000 people suggests that under-25 check their phones 32 times a day. Statistics also suggest that 43 percent of under-25s experience genuine irritation or anxiety when they can’t check their phones at will.
According to the international survey, opticians are concerned that overexposure to light from electronic devices could increase the risk of eye problems.
They are warning that overuse of smartphones and other devices like tablets, computers, and flat screen TVs can lead to long-term damage.
The survey, commissioned by a group of independent opticians, found that on average an adult spends nearly seven hours a day staring at a screen, with nearly half feeling anxious when away from their phone.
It also found that 55 percent felt the amount of screen time they’re exposed to affects them, with eye discomfort the main problem.
According to optician Andy Hepworth: “Blue-violet light is potentially hazardous and toxic to the back of your eyes. “So over a long period of time it can potentially damage your eyes. “When you’re looking at a smart phone, the light peaking out of that is blue-violet.”
Hepworth says that tests have found that over exposure to blue-violet light has the potential to put us at greater risk of macular degeneration, a leading cause of blindness.
Opticians note that although “good” blue light (blue-turquoise) is needed to help regulate biological clocks, it is also thought that extensive exposure to blue-violet light can disrupt sleep patterns and affect moods.
“Although we don’t know if there’s a direct link with it creating eye problems, there is strong lab evidence it can potentially do that,” Hepworth added.
“It’s the combination of not blinking enough and bringing the device closer than you normally look at objects – it strains your eyes.”
Amanda Saint, another optician, says the advice is simple. “Get your eyes tested regularly and take regular breaks from your computer and hand held device.”
