HOW TO FILL YOUR PRESCRIPTION

IF YOU HAVE QUESTIONS ABOUT READING AND FILLING OUT YOUR PRESCRIPTION, THE FOLLOWING IMAGES CAN HELP YOU UNDERSTAND THE PROCESS.

This is what you’ll likely see. The top and/or the left side of the form usually include terms such as OD, OS, SPH, CYL, etc., either printed digitally or handwritten by a doctor or optometrist.

[ OS/OD ] OS: Oculus sinister, meaning left eye; can also be represented by “L”. OD: Oculus dexter, meaning right eye; can also be represented by “R”.

[ SPH ] SPH is short for sphere. It shows your degree of myopia/hyperopia, in other words, nearsightedness/farsightedness. A negative number here indicates myopia, therefore, -5.50D means 300 degrees of myopia. A positive number here indicates hyperopia, therefore, + 2.50D means 250 degrees hyperopia.

[ CYL/AXIS ] CYL is short for cylinder. It indicates your level of astigmatism, a condition where the cornea is irregularly shaped and causes blurred vision. AXIS, the axis, describes the direction of astigmatism. -1.00 means 100 degrees of astigmatism. 100 means that the astigmatism direction is 100 degrees.

[ PD ] PD refers to pupillary distance, or the distance between your pupils.

HOW TO MEASURE YOUR PUPILLARY DISTANCE(PD)

WHAT IS PUPILLARY DISTANCE?

Pupillary distance (PD), or interpupillary distance (IPD), is the distance between the centers of the pupils when both eyes are looking straight. It is measured in millimeters. The average PD for adults is between 54mm to 74mm, and for children, between 43mm to 58mm.

WHY MEASURE PD?

Pupillary distance (PD) has a huge influence on our comfort level when we wear glasses. You must provide your PD when filling out the prescription form on our website.

The pupillary distance (PD) between your eyes should match the distance between the center of your lenses, and the image should be clear.

< THE SUITABLE PAIR OF GLASSES >

The PD of the eye deviates from the distance between the centers of the lenses. If PD is small, wearing large-frame glasses will cause focus deviation between the pupils and the centers of the lenses.

< OVERSIZED FRAME >

HOW IS PUPILLARY DISTANCE MEASURED?

Your eyeglass prescription will usually come with pupillary distance (PD). What if you don’t know your PD?

MEASURE YOURSELF FIRST, YOU NEED A RULER AND A MIRROR.

Step 1 ↓ ↓

Stand upright and face the mirror, then align your face horizontally with the center of the mirror.

Step 2↓ ↓

Place the ruler above your eyebrows and make sure they’re parallel to your eyebrows and to the ground. The distance between your two pupils is your pupillary distance (PD).

IF YOUR FRIEND HELPING YOU MEASURE YOUR PUPILLARY DISTANCE

1. Please open your eyes, look straight and don't tilt your head. 2. Ask your friend to place the 0 scale on the scale above the center of one pupil and note its distance to the center of the other pupil.
