Making any diagnosis from a photo is often challenging. Photos sometimes do not fully represent all the features of the lesion in question.
An important question to consider is when the lesson was first noticed? Very commonly, long-standing pigmentation on the conjunctiva as seen on the photo can simply be a nevus, or “mole”. Spots that require closer medical attention are those that are of recent onset and progress rapidly (few weeks and months) as this may indicate the presence of a tumour instead.
Quite frequently, there is no need to remove the nevus, as it is often harmless. But one can still choose to have it excised for cosmetic purposes.
Do see your ophthalmologist if the above lesion gives you cause for concerns.
