They do look like some animal's eyeballs! How interesting! What is the texture like? I'm guessing a gelatinous exterior. Is the dark inner part a hard seed, or more like a crunchy nut?
These had been peeled of their brownish papery skin. The 'eyeball' is a hard, inedible seed and is surrounded by the slightly transparent flesh.
I would describe the texture as grape-like. They are related to rambutan and lychees and similar to them too. More like lychee in flavour. But smaller.
Should you find any, the seeds are relatively easy to sprout and you can grow your own tree.
Here are the unpeeled longan.
