My minecraft is blurry and it won't let me click Super Secret Settings?

My minecraft is blurry and when i break blocks it looks extremely weird. I'm currently using 1.7.4. I was told it was Super Secret Setting but to top this off, it won't let me click on Super Secret Settings. All it makes is random noises!

The random noises shows you your using it. After restarting Minecraft It should go away

The "Super Secret Settings" button doesn't actually bring you any options. In fact, the random noises will happen every time you click on it, and it will also change the current filter. If you press f3, you should be able to see the shader/filter being used. Just keep clicking that button until your back to normal! Hope this helps!
