cornea <\/a>scratch can lead to red eyes. The cornea is very sensitive and fragile. While your eyes are meant to blink and protect the eyes from injuries, they can still allow foreign objects to enter the eyes and scratch the cornea. Even tiny objects that you can\u2019t see can cause damage to the cornea. The longer the object remains in the eye, the worse the scratch can become. <\/p>\n\n\n\nEyes can be flushed with water to try to wash away the object. In some cases, it may be necessary to have the object removed with surgery. As long as the cornea is scratched, the eyes can remain red. Even after the object has been removed, the eye or eyes may stay red. Once the scratch heals the eyes should start to heal and the redness will go away. On rare occasions, the eye may stay red for long periods of time.
