Smartphone overuse could damage eyes, say opticians

People who are so addicted to smartphones they may be increasing their risk of eye damage. Opticians warn that overuse from phones and other devices such as computers, tablets, and flat screen TVs can lead to long-term damage. Andy Hepworth, a UK-based optician said: “Blue violet light is potentially hazardous and toxic to the back of your eyes. It’s the combination of not blinking enough and bringing the device closer than you normally look at objects, it strains your eyes, Hepworth added. “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.”
