How do I order online with my prescription?

When you have chosen your frame, click the 'Buy Frame or Add Prescription' button.
ou can then select 'Single Vision Lenses' for if you require glasses for reading or distance. 'Fashion Accessory' if you do not require prescription eyewear & 'Frame Only' if you would like to get your lenses fitted locally.

If you chose 'Single Vision Lenses' then you will have the option to upload your prescription which allows you to select or take a photo on a mobile phone, tablet, or select an image from your computer. Or if you would prefer, you can select 'Enter Manually' which will allow you to input the details for your OD + OS, we will also ask you to upload your prescription just so we can double check all the details in our lab. Your final option is to 'Email Later', this way you can
get in touch with our highly-trained customer service team via email. We'd recommend this method if you have any questions or special requests, our team can talk you through the ordering process.

You can find further information about ordering prescription glasses here.

How do I get a prescription?

Once you've had an eye examination at your local 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.

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 much will my glasses cost?

Once you have chosen the frame you would like, click 'add prescription lenses' then select your lens package from TruOptics, Essilor and ZEISS [which ranges from +£20.00 to +£800.00] and any additional coatings you may require such as anti-reflection, blue control and Drive. You can also add transitions if you wish to have your clear lenses turn brown or grey when you move into bright light.

You will then be quoted a price based on your prescription and package selection.

Please be aware, if you have a more complex prescription we may have to surface your lenses at an additional charge. A member of our qualified customer service team will be in touch once we have received and read your prescription to notify you of this cost [in most cases, this is approximately an additional £30 charge].

How do I measure my PD?

You can ask the optician or store where you last purchased glasses for your PD [pupil distance] measurement as they will have measured and noted on your records.

However, if you'd prefer not to ask then you can measure using a number of smart phone apps.
We recommend: 'EyeMeasure' [for Apple iPhone] or 'GlassesOn' [for Samsung/ Android Users].
Both of these apps take advantage of latest camera technology resulting in measurements as accurate as any in store/Optician measurement devices.

What size of glasses should I choose?

Glasses can come in all shapes and sizes and it can be a matter of personal choice what size of frame you go for.

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. These numbers refer to the lens width - 47mm recommended for those looking for a smaller, more narrow frame, where as 53mm or above will provide you a much larger eyewear design.

The above graphic displays the four most common sizes that you will come across while browsing for frames. However, if you have a specific sizing question or request then please feel free to get in touch with our qualified team who will be able to assist.

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 second is the bridge width and the last is frame length. We have them listed in the 'DETAILS' section on the right hand side of our product pages.

The first number in the above image refers to the lens width. As explained above, many of our brands design their frames in multiple sizes, quite often 47mm, 50mm or 53mm. This measurement is dictated by your eye size and is the horizontal width of the lens in millimeters. If you are measuring a current pair, then please ensure you measure the inside of the frame rather than the outside.

We often add the lens height to our product details, but this is less commonly featured on the inside leg of your frame, this is the vertical height of a lens and it is measured from the top to the bottom of the lens excluding the frame.

The second number on your glasses leg will tell you the bridge width. 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. Most commonly brands create their eyewear designs in 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.
Our lenses also come 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.

You can learn more about each of our brands, coatings and packages here.

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 'Add Prescription Lenses', then 'Fashion Accessory'.

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, you can select 'Varifocal/Progressive' when you click 'Buy Frame or Add Prescription' on the product page.
Please be aware, we may get in touch with you before creating your custom lenses so we can discuss your varifocal requirements further.

Our varifocal lenses are only available to UK-based customers. You can find more information about Varifocal Lenses here.


Do you supply prescription glasses for children?

Supply of prescription glasses to those under 16 is not possible 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 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.

Can I return prescription glasses ordered with free lenses?

If you choose a free lens option then your return refund will be reduced by a minimum £20 plus further deduction of any lens upgrades. Prescription eyewear is a custom item and will require further work and lens refitting before we can restock.

What is the maximum prescription that you dispense?

We will cater for single vision prescriptions in the range to +/- 8.00, however only where we can obtain accurate centration values for both monocular PD and heights. This range is reduced in the case of Varifocal Lenses where the maximum prescription is +/-6.00.

I have ordered prescription sunglasses. Will I get original plano sunglass lenses?

We do not normally supply original sunglass lenses if we are fitting prescription sunglass lenses to the frame. If you have a special request for the lenses to be supplied please request in advance as we are unable to supply after delivery.


What is RE-LENS?

Re-Lens is our re- glazing service. We can take your current frames and add any lenses from our portfolio.

Re-lens is a great option if:

  • Your prescription has changed and you need new lenses for your existing glasses.
  • You damage, scratch or chip your current lenses and wish to replace them.
  • You would like to upgrade or change your current lenses with a different type lens or added coating.
  • You have purchased a new frame and require us to fit your lenses.

Not only are you saving money by choosing to re-lens, but there is also a positive environmental benefit to keeping your existing glasses.

Why consign your older glasses to a drawer when you can let us fit new lenses!
Let us prolong the life span of one of your favourite frames.

How much does it cost to have new lenses fitted to my old frame?

New lenses start from only £30 (plus postage).
You can see all available lens options and prices as you move through the order process. Please visit RE LENS for further information.

If you need any help with pricing please get in touch.


Do you RE-LENS all frame types?

Yes, we can fit new lenses to all types of glasses including rimless frames [this includes brands such as Lindberg and Silhouette].

We also fit lenses to brands such as ic! berlin, which not every optician can...
This is a highly-skilled process therefore there is a small additional charge for special frames to cover extra lab work.

My frame is quite old, is that a problem?

No, this not a problem. However, we do reserve the right to refuse an order if we consider there is chance that the frame may break during the re-lens process. If this is the case, we will refund your payment and return your frame to you free of charge.

What happens if my frame breaks during the re-lensing process?


All orders are accepted on the basis that the process is at your risk.
We will refuse & refund orders if we foresee breakages as a potential outcome.

However, if we accept your glasses to fit new lenses and they break during the process then we cannot accept responsibility. Our acceptance of your order, or notification that we consider the frame to be at high risk [susceptible to breakage] during process, does not make any damages our responsibility.

If a breakage does occur then we will try to arrange a replacement at cost price. However this may not always be possible.


Can you measure prescription from my old glasses?


Yes, we have accurate lens meters which can measure your prescription.
We can also measure where your varifocal [progressive] lenses are fitted within your frame should you wish for us to replicate in your new lenses.


How can I tell if my frame is suitable for RE-LENS?


We recommend that you take a close look at your glasses and consider if they are worthy of new lenses? In particular, please check plastic frames for presence of small cracks or white marks which may indicate that the material is likely to break when undergoing the relens process.

If you are unsure and require a second opinion, please feel free to send us some images of your frames [you must ensure your images are clear, sharp and well lit. Your images must capture any wear and tear on the frame].


Can you fit new nose pads to my glasses?


Yes we will replace nose pads with silicon pads. Please note, we will not be able to replace designer branded nose pads. If you send a frame with designer logo nose pads please let us know if you will be satisfied with non branded pads. If so, then we will replace your nose pads free of charge.


How can I order varifocal lenses?


Yes, you can order varifocal lenses in the same way as our single vision lenses.

However, we may require some extra information from you in order to accurately re-lens your varifocal glasses. Once you have placed your order, our advisor may call and ask for some photographs of you wearing your glasses. These photos will allow our team to accurately measure your eye position within the frame.

If you already have varifocal lenses in the frames you are sending for re-lensing then we can measure the optical centres when we receive your glasses at our lab.


How long does the process take?

This service can take between 4 to 10 working-days in total. Our advisor can give you a more appropriate estimate when they call to discuss your order.

Our standard free post label is sent with Tracked 48 hour post. Once your glasses are at our lab, it can take 2 working-days to process your new standard lenses. Varifocal lenses and lenses with special coatings can take up to 5 to 7 working-days to arrive with us at our lab.

If you do require an express service then do ask and we will do our best to get your glasses to us and back to you as soon as possible.


I have rimless glasses, do I need a special lens material?


Yes, rimless glasses require a slightly tougher material. We strongly recommend that you choose either a 1.6 or 1.67 index lens material. As the lens edge is exposed in your rimless frame, it is best to fit rimless glasses with a tougher lens material.

A standard 1.5 index lens is more brittle and susceptible to edge chipping. Also, as our lab will need to drill holes into the lens to fit your lenses, the 1.5 lens can be a little too soft allowing the holes to widen leading to the lenses loosening within frame.


Do you reglaze Lindberg frames?


Yes, we can re-lens all Lindberg glasses.

We send all Lindberg frames to a specialist lab who have extensive experience fitting lenses to Lindberg frames. This requires special equipment, and most of all a highly skilled technician.

If your optician is not used to fitting new lenses to Lindberg glasses then the quality and security of the lens fitting may be less than perfect. Therefore this specialist service with extra care and attention does necessitate a small added fee. Please contact us for a quote.


How can I send you my prescription?


You have multiple options to provide us with your prescription. You can upload a photo, enter your prescription manually into our online form or email us a photo of your prescription values. Alternatively, you can ask us to replicate the prescription currently in your glasses by sending your glasses to us.


How can I give you my pupil distance (PD) measurement?


You can provide your pupil distance in the prescription form on our website. There is an space for you to enter this alongside your prescription.


If you do not know your pupil distance, you can contact your optician and ask. Your PD value is something that all UK opticians note on your prescription. In most cases, your optician will give you this free of charge as it should already be on file [if you have previously ordered glasses from that specific store].

However, if you are unable to contact your optician or they do not have this information available, there are now smartphone apps which you can use. The app will take an incredibly accurate measurement of your PD in just a couple of minutes. For iPhone users we recommend ‘EyeMeasure’ and for Android users we recommend ‘GlassesOn’. Both these apps are free and only takes a couple of minutes to download and use.

If you are struggling to download or use either of the apps, or if you have any further questions about your pupil distance, please contact our team. We are more than happy to talk you through the measurement process and assist where we can.

Once you have your measurement, please share the figure with us via the online prescription form or by email.
