Blindness And Night Vision Doesn't Create Complete Blindness Anymore

Ive Usually Made FNAF Maps On Minecraft, And Messing Around With Effects And Found Out That Blindness And Night Vision Create Complete Blindness, Perfect For Jumpscares And Effects For Map Makers, But After Updating Minecraft, The Combination Of Night Vision And Blindness Now Make This (Image 2). Why? What Happened? Why Do We Need Blindness WIth A Brighter Circle/Floor? Whats The Point?
It Would Be Awesome If You Could Fix That Bug And Bring Back Complete Blindness, Or At Least Have It As A New Effect For 1.9
Thanks So Much For The Support! This Really Helps!
