At Butterflies Healthcare, we try to make sure our customers are always 100% happy, not only with the products they buy but also the service we provide. However, buying online can seem more difficult for certain products. We want to reassure you that we offer you an easy and trustworthy online service. As we are owned by a qualified optometrist, we really understand your visual needs.

Our customer service team are always happy to offer advice and guidance for product selection or any enquiry you may have. We can offer expert advice on the best prescription goggles for your needs and are able to supply prescription goggles to suit most people.

You have the right to cancel the contract at any time up to the end of 14 days after the day on which you receive the goods (30 days in the case of faulty/damaged goods). To exercise your right of cancellation, you must give written notice to us by post or e-mail giving details of the goods ordered and (where appropriate) their delivery.

Off the shelf goggles

If you purchase any ‘off the shelf’ goggle from us, so long as it has not been used in the water you can return in the original packaging for a full refund or exchange.

Custom made goggles

Custom made products, such as the Swimvision II, can only be returned if there is a fault with the goggles. For this reason we offer a trial fitting service where we can send you an empty goggle to try on first to ensure the fit is suitable. Please contact us for more details.

Should you find any fault with your goods then simply return them to us explaining the problem. We will then either rectify the matter or offer a full refund. Please bear in mind the following:

  • When you receive items you have ordered, we recognise that you may want to try them on to ensure the fit and feel is as you envisaged. In the case of swimming goggles do this before using in the pool, for swimwear wear underwear underneath.
  • Please remember, we can only issue you with a refund or exchange if the returned product concerned is in a fully re-saleable condition. This means that they must be unused and in the original packaging.
  • Return postage and packing costs will be met by the customer (except for faulty/damaged items) but no postage and packing charges will be added for exchanged items.

I purchased a basic mask for snorkelling over coral reefs and have not had a chance to try it in full action, but it seems from a cursory test that it is just what I wanted.

Very satisfied with my mask and the added prescription to the goggles was great. Quality is very good and the price was much better than I could find anywhere else. I paid close to 70% less than at an eyewear store. I again recommend.
