Why does Antonio specifically cite young people? “They have very clear lenses”, he explains. For now, it’s yet to be seen in clinical practise.” Using Devices at Night Maybe in 20 years we’ll start seeing patients – young patients I’m afraid – who’ve been using phones and computers, with some damage that we’ve never seen before. “This kind of damage is not going to happen overnight. “We’ve only been using mobile phones and tablets for the last 10 years”, Antonio begins. And while some recent studies suggest this exposure will have detrimental effects on our eyesight, Antonio Uceda-Montanes, Consultant Ophthalmic Surgeon at Optilase Eye Clinic, says that at this stage, it’s too early to tell what that damage might look like. We’re exposed to it through technology smartphones, tablets and computer screens, for example.

There’s been a lot of talk in the media lately about blue light its potential to harm our eyes and even cause eventual blindness.
