FAQ

1.) Do Sightline multifocal reading glasses have magnification at the top?

Yes- and here is why: 

Sightline multifocal progressive power reading glasses have a lens designed for maximum comfort and easy user adaptation. 

A frequent problem with prescription progressive lenses is people have trouble adapting to progressive lenses.  Sightline lenses are unique - the lens production process is patented, and the design was developed with maximum comfort and ease of adaptation in mind.  In order to do this, we make the lenses with a very "soft" power transition.  We need the full height of the lens (the lens B-dimension) to allow for a smooth and comfortable power magnification transition.  (This is why none of our frame models have a B-dimension of less than 28mm.) 

So why no zero magnification at the top of the lens?  To design a lens with zero magnification at the top, we would need to have a much more abrupt transition to the section of the lens that provides the proper level of magnification for the task at hand.  In effect, you would have a lens that was not very progressive and would be closer to a bi-focal design.  Doable, but not comfortable.  

(Foster Grant used to offer a product called "All Day" (I think) reading glasses.  They had zero magnification at the top.  BUT, I cannot find these on the web or in stores anymore.  They seem to have discontinued them.  My guess is they were to hard to adapt to for most wearers. February 01, 2021.)  

Sightline multifocal readers maximize comfort for reading, working on a computer and near vision tasks.  We have nailed this tricky balance and have thousands of happy customers who feel the comfort of Sightline progressive power reading glasses.  Satisfaction guaranteed!

2.)  Is there a period of time where I need to get used to multifocal reading glasses. 

Nope! "If you have to adapt, send them back."  

Lots of our competitors will tell you the progressive lenses take some time to adapt to. We think this is poppycock.  We designed Sightline lenses specifically so you would not have to adapt to them.  The analogy is a pair of shoes:  If the shoes are not not comfortable in the store, they are probably not going to be more comfortable at home.  We do offer some fit guidlines, and since we use optical quality frames there are adjustments that can be made to improve performance.  

 3.)  I see Sightline Readers on eBay, are the multifocus?  

NO! 

We do not sell on eBay.  The reading glasses on eBay are not multifocus, they are regular reading glasses that were sold in a brick and mortar retail store chain that went bankrupt.  There are three ways to buy authentic Sightline Multifocus Readers - on our website, on Amazon, or Walmart's website.  The best selection and price is on this website. 

4.)  What about if I use a quarter diopter like a 1.75?

No worries.... simply round up to the next highest power.  

Since the lenses have different powers in them, you will find a comfortable spot for reading as you look through the lens.  What you don't want, is not enough magnification - hence, round up.
