Orders & Payment

So you’ve decided to order! Want to know anything about the process? Rest assured, we’ll be doing our best to get your sunglasses to you safely.

How can I pay for my order?

We accept payment by Visa, MasterCard, Maestro, American Express and PayPal.

How can I cancel or amend my order?

For standard sunglasses and ophthalmic frames without prescription lenses we’ll be able to cancel your order and payment transaction if you get in touch with us prior to dispatch of your parcel. Orders for prescription eyewear are put into production almost immediately after receipt of the order, but we can normally cancel an order if you let us know less than an hour after ordering.

How long will my order take?

This will depend on what you have ordered. If your order is for a non-prescription pair of sunglasses then your order will be dispatched immediately and will arrive in the length of time indicated by your delivery option. Your prescription order will take longer, indicated by the length of time quoted on the product page when you added the purchase to your basket.

Why do prescription orders take longer?

Prescription eyewear is bespoke, made to precise specifications to ensure you receive accurate corrective vision. When we receive your order, your prescription is checked by us to verify its accuracy and suitability for your selected frame. Production work for your prescription lenses is handled externally by one of several leading glazing labs. Once your lenses have been produced, they are shipped to us for a final quality check before being forwarded on to you.

Fitting & Style

We love shopping online, but sometimes it can be hard to know if you’re picking the right frame for you. If you want to know anything more about the frames we offer then these questions should tell you all you need to know.

Which frame size is right for me?

Frame sizes on Tortoise+Black are standardised, and take into account the width of the lenses and the bridge. We list frame dimensions on every product, so if you already own a frame and know its frame dimensions then you have a great point of reference! For more detailed help with frame sizing you can consult our handy Size Guide.

Which frames will look best on me?

If you’re struggling to set on the right frame for you, or feeling completely lost as to what would work, then try our Personal Shopper service to narrow down our selection based on your preferences.

Can I try frames before I buy them?

We offer a Home Trial service, allowing you to try on up to three frames at home to make sure the fit and feel is to your satisfaction. Alternatively you can visit our Store and try on as many frames as you please!

Can I adjust my frame to improve the fit?

Many of the frames on Tortoise+Black are designed to accommodate a wide range of face shapes and sizes. Some frame materials allow for a degree of adjustability but this is not something we recommend the customer perform as it may lead to irreversible frame damage. If you’ve bought a frame and feel like it could do with a tweak then contact us for further advice.


We consider prescription eyewear our speciality, collaborating with some of the world’s leading optical labs. Got a question before you place your order? Maybe you can find the answer to it here!

How do I read my prescription?

If there is anything you are unsure about, please get in touch and we will be more than happy to help.

Do I need extra measurements for varifocal (progressive) lenses?

We’ll need a few extra pieces of information in order for you to order varifocals.

  1. NEAR/ADD measurement. This should be part of the prescription given to you by your optician.
  2. Pupillary distance or PD. This may or may not be part of your prescription. If you require a PD measurement then you can contact your optician who is obliged to supply this information to you.
  3. Height measurements. This will not be on your prescription, but is essential for accurate varifocals. We establish this by sending out a disposable demo frame, which will arrive in the post shortly after ordering. You will need to follow the instructions we will email, and then send a photo back to our dispensing opticians. They will then work there magic, and then get the glasses into production. Because of this, please allow a couple of extra days for varifocals, as we can only start production once we have your photo. Read More

How do I add my prescription to my order?

You can add all your prescription details using the form available when adding your prescription in the basket. You can attach a photo or PDF or you can select to send later, if you select send later you can then email your prescription to us using lab@tortoiseandblack.com and quoting your order number.

My prescription is more than two years old. Can I order?

We require that your prescription is no more than two years old in order for you to place an order.

I have a strong prescription. Are you able to accommodate it?

No problem. Nonetheless, we recommend contacting our team if you have any concerns about the strength of your prescription. We can tailor solutions if required, and all orders will be overseen by our in-house dispensing optician.

Product Care & Warranty

A little TLC can help your frames give a lifetime of sunshade service. Find some pointers within. Alternatively, if you’re feeling let down by the quality of your purchase then we’ve also fielded some questions on warranties.

How can I take better care of my eyewear?

All of the eyewear we sell is typically supplied with one of either a microfibre bag or hard case, or in some cases both. We recommend always storing your eyewear in either its bag or case when not being worn to stop the accumulation of dust. If your lenses are dirty, only clean them with the bag or cloth supplied with your eyewear. If marks are stubborn, warm water should help to lift the most stubborn smears. Never use detergents or abrasive materials when cleaning your eyewear!

My eyewear is damaged. Is it covered by warranty?

All of our eyewear is normally covered by a 1-to-2 year warranty period covering manufacturing defects. Warranties will typically never cover accidental damage, including lens scratching. If you’ve encountered a problem with your product then don’t hesitate to Contact Us to explain your issue.

How long does the warranty last on my eyewear?

Warranty lengths typically vary from 1 to 2 years, covering manufacturing defects. Prescription lenses are also covered by a warranty period. To get more information on the warranty policy for your purchase or a brand you are interested in then get in touch.

Will my eyewear come with a case?

Your eyewear will always come with some form of portable storage, in the form of a microfibre bag, hard case or both.
