Old One Eye

The combination of very unhealthy-to-hazardous air and the amount of time I've been spending at the computer has set my eye to twitching. My left eye is a little weaker than my right, and while my eye doctor says I don't need a new prescription, enough eyestrain and fatigue (and in this case dust and smoke) makes it start twitching. In order to get anything done at all, I dug out my eye patch to give my left eye a rest. Now I need to be careful not to run into things due to a lack of stereoscopic vision.
