Reduce this if the highlights are to importent.

If you reduce this value, the highlights will get sharper.

Adjust the first value to set the minimal reflective value. That valus 
is used when the surface is viewed perpendicularly.
Adjust the second value to set the maximal reflective value. That value 
is used when the surface is vewed at a grazing angle.

You can add an optional "exponent Float" here. It will affect the 
falloff of the reflection.

Important. Keep that.

If you change the interior, the reflection will change as the fresnel 
reflection is ior dependent.

You can try with: reflection{0.05, 0.7 fresnel}

This will gives you a notably less reflective glass.
