How to Order Glasses Online With Confidence

Yes, you can order glasses online with confidence if you know your measurements, pick a frame size that matches a pair you already wear, and shop somewhere that offers a clear return window. At IGIOO, orders over €99 ship free and every pair comes with a 14-day fit & style guarantee.

Start with what you already know

Most ordering mistakes come from guessing. Before you open a product page, gather three things: a current prescription, your pupillary distance, and the size printed on the inside of your favourite old frames.

• Prescription: if the abbreviations look confusing, our prescription guide explains each column.
• Pupillary distance (PD): the distance between your pupils in millimetres. See how to measure it at home.
• Frame size: usually three numbers, such as lens width, bridge and temple length. Our frame size guide shows where to find them.

Choose the frame by comfort first, colour second

A frame that looks great in a photo can still pinch behind the ears. Compare the measurements on the product page with your reference pair, and pay attention to material: acetate feels solid and holds colour well, while lighter materials suit all-day wear.

If you are unsure of your shape, the face shape guide narrows the field quickly. Then browse the full eyeglasses collection and filter by shape.

What to expect at each step

Lens choices without the guesswork

You do not need to be an optician to choose lenses. Decide how you will use the pair most: distance, reading, computer work or a mix. Single vision covers one distance; progressives blend several. If you are weighing add-ons such as blue-light filtering or a driving lens, pick the one that matches your longest daily activity rather than buying everything.

Many people find a quick note of their daily routine helpful: hours at a screen, night driving, time outdoors. That list usually points to the right options within a minute.

Double-check before you pay

1. Prescription numbers match your paperwork, including plus and minus signs.
2. PD is entered in millimetres, not centimetres.
3. Frame colour and size are the ones you intended.
4. The delivery address and phone number are correct.

Two minutes here prevents most remakes and delays.

When the first pair arrives

Wear the glasses indoors for a few hours before judging them. Look straight ahead, then at something close, and check that the frame sits level and does not slide when you look down. A new prescription can feel different for a day or two, which is normal. If the fit or style is not right, the guarantee window gives you time to decide.

Common mistakes to avoid

Three slips cause most disappointments. First, choosing a frame purely on colour without checking the lens width, which can leave the glasses too wide or too narrow for your face. Second, entering a PD estimate instead of a measured value; a small error matters more with stronger prescriptions. Third, ordering a style you have never worn without looking at how it sits on a face similar to yours.

A simple habit helps: open the product photos, look at the model shots, and picture the frame next to your usual outfits and hairstyle. If the shape feels like a stretch, choose a close cousin of a pair you already love, then explore bolder styles on your second pair.

Keep your paperwork handy

Save your prescription and PD in your phone notes, along with the frame size of any pair that fits well. When you reorder, or want a sunglasses pair with the same values, you will have everything in one place and the lens selector takes only a couple of minutes.
