Since many of us already have jobs or small children to which we cannot take our eyes off of, I suggest that whenever you DO NOT need your eyes, close them.
If you are stirring a pot to cook, close your eyes and focus in on the smells and sounds of cooking. If you have a moment to write, try writing without the aid of vision. Try typing or blogging through key memory alone. If you are on the phone and do not need to see (don't do this in a car!) then close your eyes for a moment and just picture the person's face, really hear their voice and try to pick up background sounds behind them.
Every small moment you have today which doesn't necessitate vision should be used to take in the other senses. Listen more. Smell more. Touch and Taste more. Just the simple task of closing your eyes while you eat will surprise you. Enjoy. :)
