Exposure to blue light

I intend to make an experiment on how your eyes are affected by blue light. And how we can take this blue light and somehow deflect or make the light darker than it was in its glow. I will be revealing the experiment soon. Sunglasses will be used in the experiment as the object that will dim the blue light. I will moreover experiment on how blue light can be deflected as a side experiment.lastly, The experiment is about what your eye looks like after exposure to blue light and we can decrease blue light to see a different result.
