No, strongholds do not naturally have Eyes of Ender.
Strongholds are generated structures in Minecraft that contain portals to the End dimension. While they are essential for accessing the End, they do not contain any Eyes of Ender themselves.
Eyes of Ender are used to locate strongholds. They are crafted using an Ender Pearl and Blaze Powder and are thrown to reveal the direction of the nearest stronghold.
You will need to obtain Eyes of Ender beforehand to find a stronghold, which can be done by defeating Blaze mobs in the Nether.
Once you have located the stronghold using the Eyes of Ender, you can enter it through the portal and travel to the End dimension.
