Choosing a Bifocal Lens
What is the difference between Standard Bifocals and Progressives? A Standard Bifocal has your distance prescription on the top half of the lens, and a magnified version of your prescription on the bottom half for reading. A Progressive Bifocal has both distance and reading like a traditionl bifocal, but with the line blended.
I realized how few visual examples of this concept exist on the internet. This diagram illustrates how they both have magnification on bottom, distance on top; note the difference between the line on the standard bifocal and the progressive.

I have a few questions.
If I order the PRIME S59 can I get the progressive bifocal which I already know my strength is 2.50
. Can I just order the glasses with just a bifocal not a prescription?
My other question is… I get headaches from the changes of extreme light from bright to dark. So would you recommaend not the polarized but the anti glare. Because I believe my migraine are triggered from the glare. Would I need both even though I prefer the sunglasses not be so dark.
Thank you much,
Caryl
