The trials arent THAT bad, everyone makes them seem unbearable. Its just after you take off the blur and them turn them back on, you see how big of a difference it is.
When you turn them off for awhile then turn them back on it makes you want to clear your eyes, like you cant see strait or your half-way drunk or something. But it does make the scenery look a lot less distracting to the eye when the blur is off.
