About the specific difference between 見えます and 見られます


I have a question about the specific usage of 見えます and 見られます.

As already explained on the net, 見えます is used when something is visible to the
speaker or comes into view. 見られます is used instead, when the speaker wants to
express that he/she "is able to see smth", like a movie in a theater. I hope I
did get that correct?

I'm now struggling with a small, but tricky sentence and I just can't wrap my
head around it. It is, translated from German into English:

From the (train) station, the fireworks can be seen, but from my house, they
can not be seen.

I have translated this into:

駅からは花火が見られますが、家からは見られません｡

I think this sentence is tricky, because the speaker both has the potential to
"be able to see" them, when the time comes, but he/she will also be able to
see them directly once they happen, so I am unsure of which form to use. If
they were happening right now (which I don't get the feeling they are), I
would have gone for 見えます, but as you can see, I decided for 見られます. I hope
someone can further explain why that is, or is not, the case and why the other
form can't be used.




I don't think your assumption about 見えます/見られます is correct. They are usually
interchangeable, and they both describe the ability ("to be able to see") and
the visibility ("to be visible"). See also: [「星が見えない＝Stars can't be seen」 but
「目が見えない＝Eyes can't see」,
why?](https://japanese.stackexchange.com/q/21516/5010)

When in doubt, you can stick to 見える, because 見られる is long and tends to have a
passive meaning today.

  * 駅からは花火が見られますが、家からは見られません。
  * 駅からは花火が見えますが、家からは見えません。

These two sentences are both perfectly correct, and mean the same thing.
Personally, I always say the latter. The
[ら抜き](https://japanese.stackexchange.com/q/36120/5010) version, 見れる, is also
common in casual settings, although it's nonstandard and must be avoided in
formal settings:

  * 駅からは花火が見れますが、家からは見れません。
