I don't know what they are or if they will affect the photos. They were hard to photograph and are hard to see in the pics. The first pic shows them the best. Other than the spots the glass looks fine; no fungus or separation of any kind.Please look at the photos carefully. They are part of the description. I charge exact cost only with no add-ons.
