Photos with red eyes are caused by the reflection of red color of blood in the eye. The natural black color of eye lenses is almost lost through the effect of the red eye. Pictures and images with red eyes of people or shining eyes of animals often look scary, demoniacal and unattractive. Gimp is a good software to retouch, correct or remove red eyes in a photo, image and picture.
Choose a fuzzy brush with a right size for the eyes that you retouch. Paint with a black color on the red eyes to bleach the red color. Keep the mouse key pressed while you paint to avoid loss of details in already painted spots.
