Not at all, although you lose the advantage of stereo vision which is the fastest way to transfer between targets. This is only .05 to .1 of a second per shot time lag. Try just placing a piece of transparent tape over the dominant eye and leaving it open. This will take some getting used too. When you close one eye you tense up your facial muscles and the other eye will have more of a tendency to blink .
Most shooters tend to prefer transfering left to right.
I think this is based on the English language. We have read left to right for so long that its just more natural and our eyes are more accustomed to it. It is worthwhile to determine which eye is the strongest and has the greatest visual accuity. This is not always the dominant eye. I tape my right eye and find that when using the isosceles stance my head is barely tilted at all.
