My progressive prescription eyeglasses give some double vision outside the sharpest zone, so I would have blamed it on the eyeglasses. When the Model X returns from it's week long vacation at the Service Center getting a tan in the parking lot, I will have to check it out with my sharpest long distance eyeglasses. I hope the younger drivers don't get too upset over this. Just wait until you reach your 60's! The vision artifacts start occurring with the slightest start of cataracts and the shrinking of the vitreous humour pulling at the cornea. If you ever see flashes of light in the dark, thousands of cells in your vision or ink like streams or a dark curtain effect, get to a retina specialist that day! Don't wait, a retina tear may cause blindness if ignored. Laser can be use to quickly repair the damage. A local hospital ER can put you in touch with a retina specialist 24/7.
