How to Measure Your Glasses

Why we ask you for measurements

Every Odian pair is made to order, so we build your glasses to the measurements you send us rather than to a fixed size. Two things matter: your prescription data, and the fit measurements from glasses you already wear comfortably.

1. Read the numbers on your current glasses

Almost every pair of glasses has three measurements printed or engraved on the inside of one temple arm. You may see something like 52□18-145. The format is always the same: lens width, then bridge width, then temple length, in millimetres.

• Lens width (the first number) – the horizontal width of one lens.
• Bridge width (the second number, after the small square or dash) – the distance between the two lenses across the nose.
• Temple length (the third number) – the length of the arm from the hinge to the tip.

If your current glasses are comfortable, send us these three numbers and we will build to the same fit. If they are not comfortable, tell us what feels wrong – too tight at the temples, sliding down, or pressing on the nose – and we will adjust.

2. Measure your pupillary distance (PD)

Your PD is the distance in millimetres between the centres of your pupils. It is usually written on your prescription – look for “PD” or “Pupillary Distance”. If it is not there, ask the optician who examined you for it.

3. Send us your prescription data

We need the full prescription for each eye: SPH (sphere), CYL (cylinder) and AXIS, plus your PD. If you have an “ADD” value for reading, include that too.

Submit it on our prescription page or email sup@odianoptics.com. We start making as soon as your prescription arrives.

If anything is missing

We check every order before production. If a value is missing or looks inconsistent, we email you before we start. That is the most common reason an order takes longer than the usual 15–20 days. You can also send a photo of your prescription and we will read it for you.

Before you order

These glasses are made to the prescription you provide. They are not a substitute for a professional eye examination. Please have your eyes examined by a licensed optometrist or ophthalmologist, and have your prescription checked whenever your vision changes.
