I was told yesterday by my eye doc that it is called Pinguecula. I just cant understand what that really means...
The doctor explained but it is not quit clear to me,, maybe its better if its a short and clear message for me to read.

It is a fleshy growth on the white part of the eye usually near the nose
and it invades the cornea(The cornea lies in front of the colored part of the eye (iris). It is not a serious problem, so nothing to worry that much.
There is no exact cause, but it occurs more often in people who spend a great deal of time outdoors especially in sunny climates. Long term exposure to sunlight.

It is believed that the primary cause of Pinguecula is exposure. We consider exposure to toxic vapors, salt water spray, exposure to the sun (ultraviolet radiation,) and damage to the conjunctiva from insufficient moisture and lubrication (tears) to be the primary causes. Sometimes, the causative factor can be related to computer use, or other intensive near vision activities. We tend to blink less when concentrating on near vision tasks which may contribute to poor tear exchange and dry eye. Pinguecula can appear after only a brief exposure to damaging chemicals or irritation. The tissue damage increases with continued exposure. It might take only a day or two to notice a new Pinguecula but weeks to resolve it.
