Nope, not true at all. Go to eyebuydirect.com, enter any random prescription and buy those glasses. I've done this like 20 times, mostly because my prescriptions were from doctors outside United States.

It's an American company. AFAIK there is no regulation in the US that requires prescription from a doctor to get the glasses.

Yes me too! This is amazing for reading glasses -> computer glasses. Converting a normal distance -> reading means adding 1.15 to one column of numbers. But it was too strong for me, so I used eye buy direct to try a sweep from 100%, .66%, and .33% and each are great for different situations

.33 of 1.15 was amazing for computers, comfortable but I can still look at distance somewhat

Maybe in the US. You can just order glasses globally (friends use HK, I'm in Europe) and nobody gives a damn about any prescription.

This thread was a reminder that I needed some prescription sunglasses.

There was an option to upload my prescription, so they could auto-detect the values from it. But there's a button just below that for "manually enter". I never saw any other prompts, on the way to checking out.
