We wrote this How-To Guide to help you better understand the important questions you should know about before buying prescription sunglasses and prescription eyeglasses online.
Understanding/Reading Your Prescription
Understanding your prescription and what everything means can be very confusing. There are many different aspects that have to be taken into account for each prescription type. To better understand these aspects further and to gain a basic knowledge on popular prescription abbreviations take a look at our How To Read Your Prescription Guide.
Pupil Distance
Some prescriptions contain more than one pupil distance (PD). In some cases, two PD is due to different measures for the right eye (OD PD) and the left eye (OS PD). Another reason for more than one pupil distance is the need to correct both distance and near vision. In this case, your prescription will state either PD near or PD dist. Please contact your optician and decide whether you require progressive/bifocals or single vision eyewear.
In order to get prescription sunglasses, you must have the correct PD, and it should be a number in millimeters normally between 54 to 70 for adults and 41 to 55 for kids.
Bi-Focal or Progressive Lenses
If you need bi-focals/progressives make sure to include Segment Height. Segment height is a must for all bi-focal sunglasses or progressive lenses. You need to have the exact frame in order for your optometrist or optician to take correct measurements of segment height.
