The invention claimed is: 1. A vehicle windshield comprising: first and second glass substrates laminated to one another via a polymer inclusive interlayer; a low-E coating provided on the first substrate, the low-E coating including from the first glass substrate outwardly at least the following layers: a layer comprising a metal oxide, a contact layer, a layer comprising silver, another contact layer, a layer comprising a metal oxide, another contact layer, another layer comprising silver, another contact layer, and a layer comprising silicon nitride; wherein the first glass substrate is an ion beam milled glass substrate where the ion beam milling eliminates fish-eye blemishes so that the windshield is free of fish-eye blemishes, wherein at least an interior surface of the first glass substrate located under said low-E coating is ion beam milled; and wherein the windshield has a visible transmittance of at least 70% and a haze value of less than or equal to 0.3. 2. The vehicle windshield of claim 1, wherein each of the first and second glass substrates are heat bent. 3. The windshield of claim 1, wherein the windshield has a haze value of less than 0.2.
