Is this normal when getting your first contacts prescription?

Hi! So I went to the eye doctor and I told them I was interested in trying contact lenses (Glasses have been a hassle, I don't feel I'm getting used to them after many months of trying). They did many eye tests, taught me how to put them on and take them off, and gave me a prescription and a bunch of pamphlets.

I kept asking if there were different options, and they kept ignoring the question. They told me to go to the next room where I could buy the lenses. So I enter the shop that was connected to the clinic and when I ask them, they say that no, I can only buy these lenses.

Is that normal? They are daily soft lenses "PureUP", UV cut, I think the brand is SEED and they also say うるおいプラス. I don't know how much they should be, but one month will be 6490 yen.
