Dear Chanel63,
I would not recommend that you use visine. It is a medicine which constricts blood vessels. When the medicine wears off, sometimes, the eyes can become redder. I would recommend that you seek the care of an eyeMD to determine the cause of the discoloration. It might be related to sun exposure.

And what do you think the brown spot is?
