Smartphone overuse may lead to cataracts, say Taiwan scientists

Here's one more proof that too much use of smartphones, tablets, and other mobile devices with tiny screens may harm the eyes: a Taiwan-based opthalmologist has noted a rise in cataract cases among heavy users of such devices.
A report from Taiwan's Central News Agency said Taipei-based Ho Yi-tao noted a rise in the number of young people suffering from cataracts.
Ho said this was possibly due to their long-term use of smartphones or tablets, most of which have small touchscreens.
The CNA report said that Ho noted an increase in the number of cataract patients between 30 and 50 years old.
One patient was a 30-year-old woman who he said was hooked on her tablet for up to nine hours a day. She would even do so while on public transport.
Eye fatigue, premature aging
Ho also noted most of his patients stare into their smartphones or computers even after work.
Such practices may lead to fatigue and premature aging of the eyes, he warned.
The CNA report said ophthalmologists have linked cataracts and presbyopia to biological aging.
In Taiwan, 40 percent of people aged over 65 are suffering from cataracts, CNA added.
But ophthalmologists also said that in the last five years, the number of cataract patients under 54 has increased by 20 percent, which may be related to the popularity of handheld devices. — TJD, GMA News
