AIBU to object to relentless upselling at my child's NHS eye test?

I took my young teen for a NHS eye test yesterday at a branch of a national optician chain. The NHS eye test for children is free. My AIBU is the "upselling" that was relentless from the minute we arrived. I understand shops need to make money but playing on parental worries about kid's health does not seem the right way to do it. Examples:

1. On arrival child was seated for the eye photos bit of the test. The staff member said they could do better photos to check more of the eye and potential health issues with a different photo. Cost £25! Setting aside the fact that the free test has been fine for years and presumably considered clinically adequate by the NHS, I did not like the inference that without the better option a serious issue might be missed and would be my fault for not paying up.
2. Child has very mild short sightedness in one eye. Usual outcome is to recall in 6 months. However yesterday we were offered very expensive "myopia management" glasses to slow down any potential worsening. Again subtle but strong pressure to buy these glasses despite my child's prescription not even needing glasses at the moment. Certainly fine to wait 6 months .
3. At the end of the test offered expensive Optegra (?) plan to monitor and predict child's eventual prescription for glasses as an adult. I did not really understand the purpose of this but she was relentless in selling it.
4. Child mentioned eyes occasionally get dry / sore after gaming / screen time. The optician suggested a warm compress held on the eyes for a few minutes. This is sensible advice but somehow I was talked into buying an eye compress mask costing £20 when google tells me a warm, clean flannel would be fine!
