How to Read Your Prescription

 1.What does my prescription (Rx) mean

 ‘+’ or ‘-‘

 ‘+’ – Shows if you are long sighted (longsightedness)

 ‘-‘ – Shows if you are short sighted (shortsightedness)

 If your Sphere (SPH) is ‘+’,you are farsighted,please tell us that after you put on the glasses, do you see further clearly or see near clearly compared with not  wearing glasses.

 Each row of an Rx has three main sections: Sphere (SPH), Cylinder (CYL), and AXIS. The SPH section corrects nearsighted or farsighted vision. The CYL and AXIS sections correct  an astigmatism.

 There may also be a fourth section on the Rx , NV-ADD (for Near Vision-Reading ADDition), which could be used to order a pair of bifocal or progressive glasses with a close-up   vision section in the bottom part of the lens.

 The SPH, CYL, and NV-ADD numbers will always have a plus or minus sign.

 

How to Measure Your PD

   PD stands for Pupillary Distance, which is the measurement from the center of one pupil to the center of the other. Your PD is an important factor and tells you where you look through the lens of your glasses and should be as accurate as possible. For people with strong prescription, this is especially important. You can normally find your PD on your prescription. Generally speaking, the PD numbers for adults stays the same. The average PD range for adults is 57-72 mm and for kids is about 43-58 mm.

 

 Your pupillary distance (PD) is the measurement of the distance between your pupils.

 This is needed for the manufacturer of the eyeglasses to know where to place the optical center on each lens, so you can see well with the glasses.
