I'm not really sure what you're getting at. You can get glasses now and not put PFAS in your eye and have improved vision. Some people don't like wearing glasses and would prefer contacts. Maybe they can make an informed decision between long term discomfort and the very low increased possibility of a future eye disease? People aren't good at long term thinking though.

re laser eye surgery, there was a story pretty recently about the number of post surgery issues being downplayed and under-represented. If you had a full and true picture of the risks then you might avoid laser eye surgery, but people running laser eye surgery clinics don't want you to have all the information.
