Yellowish spots onthe eyes

I’ve noticed on various people yellowish (fatty-looking) flecks on the whites of the eyes. What are they–just fatty deposits? And what causes them? They are raised, but still under the outer layer of the eyeball tissue.

Any ideas???

Is it this?

Sometimes you get those yellow spots and it doesn’t mean anything. Sometimes you get them and it’s a symptom of something more serious.

Sounds like textbook cases of pinguecula.
