Oh okay so, apparently the way contact lens prescriptions in the US work is that you get a scrip not just for a lens power, but for a specific brand and model of lenses.
How does the optometrist figure out what to prescribe? You try on a couple options and tell them which one you like. It's literally preference.
You can't just tell a company "oh I need this brand and this power" and have them ship it to you. You need a specific prescription that's less than a year old.
Bullshit.
@starkatt if you photoshop the date off the script and send it that works too <3
Like okay sure getting up-to-date lens strengths is good.
But I am confident that the which particular lenses optometrists have you try on and then write a prescription for is more a function of marketing than anything else.
