Officially, it has always been there, to check prescriptions. I’m not convinced it is a real change in any regulations in the US as I have only seen this message from Vision Direct so far.
But we will find out in a few weeks I guess…
Actually there is a website called https://www.contactlensesplus.com (same as contactlenses.co.uk).
They say you will need your prescription. But then in the customer help section you will see:
Getting your prescription
Your prescription can be found on your existing contact lenses box. Grab them. Once you have this and the name of your lenses, it is easy to find and order them online.
Alternatively, ask your Optician or Eye Doctor for a copy of your
Contact Lens Prescription. You will find on it all the details to enable you to order online. Make sure you get a contact lens prescription and not a spectacle prescription, as they are different!
We do not require to see your contact lens prescription when you order contact lenses. When you order from us, you will need to agree to our Terms & Conditions which indicates acceptance that your prescription is current and suitable for you. It is important to have an annual contact lens checkup with your eye care practitioner to ensure that your eyes stay healthy.
So maybe it’s possible to order lenses without Optician prescription, too? Maybe they just want to make sure you know what you are doing?
