The sunsceen idea is good because it's specifically designed to stop UV light. You can also go to a junkyard and 'borrow' a tinted window or get a piece of glass tinted at one of those car shops.
I'm not sure about this problem, some eyewear manufacturers developed orange/yellow/brown lens and claim they all can filter UV and blue light.[attachment=18774]
I'm not sure about this problem, some eyewear manufacturers developed orange/yellow/brown lens and claim they all can filter UV and blue light.You need to detect that using sophisticated apparatus. As an programmer who stares at multiple computer screens 8-10 hours a day, I bought a pair of computer glasses from Taime Optics a few weeks ago, they claim that the eyewear can filter 97% of blue light and 100%, I'm still not sure I really need this, but feel much better when staring in front of the computer.The images belows are the test results(with or without the bluelight protection glasses)
