I got a few that I seemed to notice all at once like 4-5 years ago. Just woke up one day with them very noticeable. They really freaked me out for those first few months. I went to an ophthalmologist every 3 months for like 9 months. I think subconsciously I was just panicking about my vision maybe going to crap. Fast forward to now, knock on wood, and I don't think about them too often. I did start buying prescription sun glasses though, very distracting in bright environments and when driving. The sunglasses really help.
The ophthalmologists are very against doing anything. Had 1 tell me there is a surgery, but he wouldn't touch me with a 10 ft pole regarding that procedure. It's for people whose vision is almost completely blurry, severely blocked in their center of vision, and ideally the patient is much older. They can dilate your eye, shine a light, and look with a magnifying glass to see them.
Again, good news is you get used to them, and I don't get bothered much by them when looking at my computer screen. I am also something of a cinephile (screening room and all), and because of how dark TVs and projectors are lit, I never see them.
When I told my gf, she got mad at me because she had several and had literally never noticed them before. I do think people that have bad vision notice them easier.
