Not really: If its from pigment, it could be because your skin is dark (we call that racial melanosis). That tends to be pretty chronic. Can't really do anything about that. If you have a new onset focal area of brown pigment, i would get it checked out by an eye md. It may have to be removed.

Sun exposure...: Sun exposure is likely the most common cause of pigmentary changes in the clear membrane of the eye called the conjunctiva. Other causes of this problem may be due to the fact that people of color may develop a non-sight threatening condition called melanosis. There is no real cure for either condition. Other causes are from a pingueculum or ptyerygium.

Can be: Contact lenses should only be prescribed by an ophthalmologist or optometrist (even if your vision is normal without them). You should never just go buy them on their own. They have to be fit properly on your eye and you need to be shown how to care for and clean the lenses in order to prevent infection. These lenses can be safely worn if they are fit properly and cared for properly.

No: Infrared cameras record light in the beyond red end of the visible spectrum. Fires, heat lamps and the sun put out far more infrared than such cameras and many of them emit no light at all but only record the image. It is the short wavelength end that is a problem such as uv light.
