There has a certain thing fallen in ny eyes. what can i do. should i put milk in my eyes?

If you believe you have a foreign body in your eye best would be to have examined by your doc or at a local urgent care. They might be able to identify the problem or further coordinate through an ophthalmologist (eye doctor) office. Putting milk in your eye would not be a good idea.

Best thing to do is flush with clean water. Many times foreign bodies get trapped under the upper lid. So gently lift up upper lid and flush with clean water underneath the lid. If foreign body sensation persists go to emergency room
