Quality - Value - Service


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.  

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. 


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.  There is no break-in or adaptation necessary for Sightline. Having said this - there are fitting guidlines, and since we use mostly optical quality frames there are adjustments that can be made to improve performance.
