Dear chuckbw65,
Double vision and blurred vision can indicate serious disease, even if transient. I would recommend that you see an eyeMD immediately.

Maybe yes, maybe no. I work on computer all the time and have never experienced this. More realistic causes include fatique, wrong glasses prescription, dry eyes, or strabismus.,and even mysathenia gravis can cause transient double vision. You need to be more observant and describe it better. Did it go away if you covered one eye. Did you truly see double? One on top of other or side to side? Did you see double out of just one eye? Was vision just blurry and not double. Make an appointment with an ophthalmologist to go over your problem. Good Luck.
