Do you need Blue Filter?
Digital eye strain can be an issue, although there's no scientific evidence that blue filter lenses can help with this. Indeed, we get more exposure to blue light from the sun than we do from computers and smartphones. It's not the blue light that's making your eyes feel bad, it's staring at the screen for hours without a break.
One of the main causes of eye strain is actually glare, so it's important you have lenses with an anti-reflective coating. Thankfully all Cubitts’ lenses come with this as standard. Blue filter lenses can potentially be useful at night when blue light from screens can disrupt natural sleep patterns. Our bodies associate blue light with daytime, so being exposed to it when you're trying to go to sleep can push our internal clocks later, meaning it's harder to doze off. Our advice is that if you have trouble sleeping it might be worth trying blue filter lenses, this isn't dissimilar to ‘Night Mode’ on an iPhone, so we do suggest trying that first. Or even trying (brace yourselves) to reduce your screen time before you go to sleep.
