How does staring all day at digital devices screen affect our eyes?
Almost 70 % of adults suffer from eye strain and blurred vision after using in excess computers, tablets and smart phones, American researchers have shown in a study presented Thursday at the CES Electronics Show in Las Vegas, according dailymail.co.uk.
People using for two hours without a break, an electronic device that requires the use of their eyes face back pain, blurred vision and headaches, and extensive research have shown that exposure to light emitted by monitors can cause macular degeneration and cataracts.
“The eyes are not equipped to view digital screens for long periods of time. These experiences may be common, but are not normal“, said Justin Bazan, optician and medical consultant for the Vision Council, which conducted the study.
The Vision Council found that Americans spend on average between 6 and 9 hours a day in front of a digital device, and the number of adults that spend over 10 hours per day in front of these devices grew 4 % last year.
“Focusing on objects at an intermediate distance – like a computer or smartphone – ultimately fatigues the eyes”, said Justin Bazan.
However, there are ways to reduce the effects of eye strain caused by digital devices. These methods include positioning the monitor in the arms, maintaining portable devices below eye level to mitigate the strong glare. Also recommended are regular breaks to rest the eyes.
Also currently developing optical solutions for these problems.
“Ocular tension due to digital devices has become a serious concern. Fortunately, the optical industry has made significant progress in recent years to develop manufacturing technologies targeting lens that causes less eye strain. Like other glasses to read and view, computer glasses are transforming the way we look at computer screens and portable devices”, said, in turn, Ed Greene, executive director of the Vision Council.
