Hi. I'm online and happy to answer your question today.
Is this little cyst on her eyeball itself?
I see you are offline, we can use the Q&A system to work on your question
This is a change in the skin around the eye (conjunctiva) from a lifetime's worth of exposure to sunlight. It is not a cancer. It also can become irritated and red at times.
Here is a link to a picture of a small pinguecula. You can find many other pictures by going to Google images:
This is link to a picture of a pterygium. As you can see one of the major differences between a pterygium and a pinguecula is that a pterygium grows across the clear part of your eye (cornea):
If you are bothered by your pinguecula it can be surgically removed fairly easily by your ophthalmologist using local anesthesia. One word of caution however.....they have the nasty habit of growing back, sometimes with a vengeance.
Does this make sense to you?
For the redness do not use visine or any drops that are for "getting the red out" as this will just irritate things more. Use natural tears to soothe and protect the eye.
Let me know if there is anything else you would like to discuss on this topic
The best treatment for this condition daily lid scrubs combined with warm compresses. I like to use baby shampoo for lid scrubs. In the shower, place the shampoo on your index fingers, close your eyes, raise your eyebrows (to stretch the skin on you eyelids) and scrub back and forth along your eyelashes for 3 to 5 minutes. The hot water in the shower helps to soften the plugged oils in the glands while the mechanical scrubbing with your soapy fingers removes the oils.
