Vision is usually recorded by having a person read a chart of various letters, which vary from being large at the top to small at the bottom. Near the bottom of the chart, there is a line of letters called the 20/20 or 6/6 line. More precisely, each element of a letter on this line (eg the width of the vertical part of the letter T) subtends an angle of a minute of arc at the nodal point of the eye. 20/20 or 6/6 vision merely means someone can read the letters on this line of the chart.
The brown spot is most likely a nevus (mole), and as far as I know there is no non-surgical method to remove such a nevus on the conjunctiva of the eye. For your information, the surgery is relatively minor anyway, and is conducted as day surgery under local anaesthesia. It involves removing the spot and patching the area with a free graft of adjacent conjunctiva to minimise scarring. Most of the time, surgery is only cosmetic in nature and so is not absolutely necessary.
