yes. tell your sister to visit an eye specailists as soon as possible. I could be caused by a condition called a thinning retna or a detached retna. Either one can cause spotting in the eye. If this problem is not fixed it can lead to blindness.
Welcome to the MedHelp forum!
What your sister has is probably floater in eye which can also be a black speck. Floaters in the eye are a sign of retinal detachment, ophthalmic migraine, a blow or fall on the head or due to some inflammation. Please consult an eye specialist for this.
Hope this helps. Please let me know if there is any thing else and do keep me posted. Take care!
