There are plenty of reasons to be worried about the length of time we spend staring at screens each day. While companies like Apple introduced features like iOS 12's Screen Time counter, a new Kickstarter campaign offers a more radical way for screen-addicted folks to kick the habit: Block them out altogether.
Inspired by the superpowered, ad-blocking sunglasses from John Carpenter's 1988 cult movie, They Live, IRL Glasses promise to turn LCD and LED digital screens black. They do this by using horizontal polarized optics. By flattening and rotating the polarized lens 90 degrees, light emitted by these screens is blocked, thereby making it look like the TV or computer in front of you is switched off. At present, this effect works with the majority of televisions and some computers, although it won't help with with your fancy new OLED smartphone or on digital billboards. That may change in the future, though.
As ever, we offer our usual warnings about the potential risks inherent in crowdfunding campaigns. However, if you want to support Cash's mission, head over to the IRL Glasses project page to pledge your, err, cash for a pair of the first-gen glasses. Prices start at $ 49, with an estimated delivery date of April 2019.
