that sounds like a classic "pinguecula"...a benign inflammatory condition usually caused by long term UV exposure.
when it gets red around it, i call that an "inflamed pinguecula" or "pingueculitis".
it is not usually dangerous, but if it gets much worse/bigger you may elect to have it surgically excised. it will not go away on its own.
FYI the brown part of your eye is the "IRIS". the intersection between the white part of your eye ("sclera") and the brown iris/cornea is called the "LIMBUS".
A related discussion,
White bump / spot next to the Iris was started.
Good question Jon,
I'm having diff. tracking down the answer.
I just noticed those small white satellite spots that look like moons at my Limbus are (reflective) and are more pronounced than I ever noticed before (now I'm middle-aged and less optic).
I think everyone has them, but can't quite nail down the terminology. The eyes have so much nomenclature, and seem complex to me, but most eye doctors are all over & around them!?
LOL, wondering why I can't get a simple answer to a common thing?
It must be the internet because I know most eye-docs are good?
Alper
also i found a great description and diagram of the eye,
however no pointer or definition of the white spot to the immediate left of the pupil?

Ok, done a bit more research and Pinguecula could possibly be it, but somehow I'm not quite sure.
