How do I order online with my prescription?

When you have chosen your frame, click the 'Add Optical Lenses' button. You can then enter your prescription details manually.

Alternatively, you can select 'I Will Upload My Prescription' which allows you to select or take a photo on a mobile phone or tablet, or select an image from your computer. If you are still unsure you can select 'Please contact me regarding my prescription' and we will get in touch and talk you through it.

How do I get a prescription?

Once you've had an eye examination at your Optician/Optometrist, you should be handed your prescription by law. If your Optician does not give you your prescription as standard, you should ask for this.

If you require an eye test, please contact us and arrange an appointment with our optician:

153 Howard Street, G1 4HF
Contact Number: 0141 552 2030


982 Argyle St,   G3 8LU
Contact Number: 0141 248 8884

183 Crown St, G5 9XT
Contact Number: 0141 429 4290

You may already have a prescription from a previous sight test, and providing it is still valid you can use that (prescriptions are normally valid for two years from the date of the eye examination).

If you have any difficulty please contact us and we would be happy to assist you further.

How do I measure my PD?

You can ask the store where you last purchased glasses for your PD [pupil distance] measurement as they will have measured and noted on your records. Unfortunately, as your request for this information is an indication that you are purchasing glasses online they may be reluctant to provide the PD. If this is the case please visit, call or email our practise at info@i2ioptometrists.co.uk and we will help you measure your PD manually.

We ask that the PD is provided for prescriptions greater than +/- 3.00 whilst lower prescriptions can be dispensed with an average value.

What size of glasses should I choose?

You may notice that in the product pages of our site you have the option to choose multiple sizes, quite often 47mm, 50mm or 53mm. However, glasses can come in all shapes and sizes and it can be a matter of personal choice what size of frame you go for.

The lens diameter is the width of the lens in millimeters measured from the bridge. If you currently wear glasses, you may find the size of your current frame imprinted in the inside arm. You will see values such as: 52 18 135, the first number lens diameter.

The bridge width is the gap above your nose and between the lenses, it is important this is comfortable for you to wear [not too tight where it may pinch your nose, and not too loose where it may fall off your face]. The second number in the example above informs us the bridge is 18mm.

The last number refers to the length of the side of your frame. This is usually 135mm, 140mm or 145mm. The side should be long enough to sit comfortably over your ears.

How do I know what lenses to choose?

We offer 4 lens options from standard to super-thin options. The stronger your prescription the higher index package you should choose.

All of our lenses come with an anti-reflection and anti-scratch coating as standard however we recommend that you can also upgrade your lenses to the Kodak Clean and Clear option which is clearer, tougher and easier to keep clean. Is also comes with a 24 month no quibble damage replacement promise - if you damage your lenses for any reason we will replace them. If you are unsure which lens to order please call our office and we will give you honest advice.

Can I buy glasses without prescription lenses?

We understand that glasses can be the perfect fashion accessory so all you need to do is select 'Buy with Prescription', then 'I'll call or email my prescription'. Please alert our team of your purchase and let us know by phone or email that you will not require prescription lenses. You should choose the standard lenses since you have no prescription.

Note that if you choose 'Frame Only', you will receive a dummy demo lens which often includes the brand logo which can obscure your vision.

Do you sell varifocal lenses?

Yes, however, we ask that you please get in touch or visit us before ordering so we can discuss your requirements.

Do you supply prescription glasses for children?

Supply of prescription glasses to those under 16 is not possible online due to regulation set by The General Optical Council [39.11 Statutory Regulation]. This regulation states that the dispensing of prescription glasses by an unqualified person is not permitted by law to dispense to children under 16 and patients who are registered as severely visually impaired or visually impaired (blind or partially sighted).

However, you may purchase the 'frame only option' and have prescription lenses fitted in person in our practise or by a registered optician in their practice. Sales of spectacles to those under sixteen or with serious visual impairment can only be made by, or under, the supervision of a registered practitioner.
