How To Buy Prescription Glasses Online

We at Frames Foundry care about your glasses buying experience. We want to make sure you are well informed to purchase your perfect glasses from us. We have created this guide to show you what information you will need and how you can easily go about selecting your next best glasses.

1. Usage

The first step is to decide what you need the glasses for.  Do you need the glasses for driving and watching television?  Are they for reading the daily paper?  Are they just for computer use?  Would you prefer a pair of glasses that did all of these?

Given below are some of the common uses of glasses:

Single Vision
These glasses are either for distance everyday wear and are good for  driving, watching television or they are for near vision tasks like reading, sewing, viewing your mobile phone etc.t.

These glasses are set specifically for you to view the computer screen at arms length comfortably.  We have specially designed lenses that reduce glare and improve visual comfort at the screen.

These are glasses which allow you to see both far and near and are seperated by a slightly visible cut off line/ semi -circle.  These are typically what our grandparents would have worn later in life.

These glasses are designed to allow you to see well at all distances from driving a car to reading a book in all in one set of glasses.  These lenses will have no lines in them and blend all the zones, seamlessly.

These are tinted glasses made to your prescription to allow you to wear them on bright days or you can get them made up to read comfortably on the beach.

2. Prescription

To make it easier for us to get you your perfect pair of glasses we do need your latest prescription.  It is a legal requirement for businesses to view your latest spectacle prescription issued by a qualified optician before we can glaze the order.  You can either email us the prescription or upload it while placing your order. 

Your prescription will depend on the usage of your glasses:

  • Single-vision lenses are typically prescribed for people who are either near-sighted or far-sighted, but not both. Single-vision lenses only have one corrective power.
  • Multi-focal lenses are usually prescribed for people who need spectacles to see things up close and far away at the same time. These lenses will have more than one corrective power.

To understand the prescription issued by your optician, please follow our Prescription Guide:

Pupillary Distance (PD) Measurement

Your PD is the distance between the pupils of your eyes. PD is measured in mm and determines the ideal spot on your lenses that you will look through. You can measure your PD by using our online tool.

3. Frame Style

Face Shape A pair of glasses should flatter your face shape. Knowing what style of frames would suit your face shape will help you select frames that will not only look good but also complement your life style.  To make the right choice, we have created a guide that will help you determine your face shape and the style of frames that will compliment it.  To view the guide, click on the button below: Face Shape Guide

Frame Shape
There are generally 3 major frame shapes around. The popularity of the frame shape is usually dependent on the fashion trends that season and manufacture releases.  However, to find the right style that is trendy yet flattering, you have to bear in mind your overall face shape.

A round style frame, will not suit roundish faces, likewise, an edgy, rectangular frame shape may not suit a wide chiseled jaw face shape.

Frame Size
Getting the right pair of glasses that fit well is important to both looking and feeling good. An ill-fitting pair will look bad and may cause you headaches. The important measurements are your eye size, bridge size and temple size.  These will affect your choice of frames. For a guide on how to find out your frame size just click on the button below:

4. Lenses

The lenses available with our glasses are described below.  


These are standard plastic lenses available for seeing things in the distance, driving, working on a computer or reading a book. The standard lenses are available in various thicknesses and our system will recommend the ideal lens to you based on your prescription.


Bifocal lenses have two distinct optical powers, one for seeing thiings in distance and the other for near distance or reading. There is a very clear distinction between the two powers often separated by a line where the top half is used to see things in the distance and bottom half for near distance.


Varifocal lenses, also known as progressive lenses help you see things both far and near including your middle vision. They are better than bifocals as there is no line visible on the lens. You can use varifocals for seeing things in distance (driving, watching TV, theatre, etc), seeing things near to you (reading a book and writing) and also to see things in the middle vision (working on computer, reading the dashboard of your car and more).

Note: The lenses used in your glasses can depend on a number of factors such as prescription, usage and frame dimensions whether the frame is full rim, half-rim or rimless.  If you have any questions, please feel free to give us a call or drop us an email.
